Note that Bravo does not permit optical type sensors to be used to monitor its DoubleWall sumps at this time.
NO. Bravo’s stance on this is that because dispensers are not made air/water tight there needs to be open air where the concrete meets the paneling for the purpose of water drainage. There are several ways that water can enter the dispenser and it should not be allowed to accumulate within. If aesthetics is a concern or if you are asked to bead a seal by an owner/operator to help keep water out during spray-downs then our recommendation is to leave approximately 1″ of open edge centered on both ends of the narrow sides of the dispenser only. This should provide adequate drainage should enough water accumulate to need an exit. Absolutely zero edge-sealing should be done on Bravo CONV-B2000 conversion frames.
If you feel that sealing the conversion frame edges would be more beneficial than harmful, we encourage you to share your unique application with us so that we can advise and provide more focused feedback.
In regards to penetrations through the bottom of a 8600 series Above ground / Marina containment sump, this should not be done on a floating dock or a dock that will be in motion for the purpose of environmental protection and fire safety. Permitting bottom penetrations would encourage the design of fuel systems that have additional and unnecessary fuel line connectors located directly below the sump unit. The 8600 series containment sumps are designed for side penetrations only.
Bravo all-fiberglass entry fittings which are rated and warranted for full fuel exposure or submersion for 30 years are not permitted to be installed to a steel containment sump wall such as that of the B-8600 series. Therefore, only flexible entry fittings can be used. Due to the low fuel resistance of flexible entry fittings (some far more than others) and despite any claims by the pipe manufacturer regarding fuel resistance ratings of the exterior of the pipe being specified, flexible entry fittings and flexible pipe of any brand should not be installed in a system that would cause these components to be needlessly and directly exposed to accumulated fuel or a fuel / water mixture. To accommodate this on any Under Dispenser Containment sump, flexible entry fittings should be installed only to a vertical wall and planned to be appropriately elevated from the bottom floor of that unit. The reasoning behind is two-fold: A) For fuel & fire containment reasons. And B) To discourage 90° degree connections or any other below the containment vessel. Piping systems exist today specifically designed for end-to-end applications such as at marinas that allow a fuel run to have no threaded connections, couplers or connectors between the two containment vessels on each end.
Though it may be obvious, entry of the fuel line should avoid penetration through the side of the UDC that is facing the operator of the dispenser. Acceptable entry points are the sides and rear of the B-8600 unit.
For stationary docks: B-8600′s can be ordered with a flush-mount flange at the upper edge to accommodate insetting into a dock for piping connections to be made below the dock surface. The flush mount variant allows the dispenser to be mounted directly to the dock. Deeper configurations can be ordered as necessary to better accommodate side penetrations for piping running underneath the dock structure.
As a rule, Bravo recommends that any and all connections should be eliminated from a piping system design installed over or near a waterway of any kind, save those at the endpoints that are secondarily contained within products designed and third party approved for fuel capture and long-term exposure.
Because the interstitial fluid is an integral part of the VPH system and DoubleWall sump, it is considered tampering if someone not certified is adding fluid, and/or if any fluid other than Bravo brand Interstitial Fluid is added to the system.
No. The Bravo Conversion Frame (DCF) was developed to contain and control falling fuel spilled from a filter replacement, or small incremental leaks within the hydraulic cabinet area of a dispenser only. This area that we targeted when we started this Secondary Containment industry does not include the often spacious “vapor panels” that are common today.
It is true that in some cases the fuel line for the exterior hose has a threaded connection at the valance-level and runs partially or mostly within the vapor panel area but it is typically a solid, continuous line running to the connection point within the hydraulic cabinet area of the dispenser. This area or the connection(s) that happen there have never before been scrutinized or required to be secondarily contained. What is more, State Waterboard staff have relayed their opinion that the Bravo DCF accomplishes its function of funneling any fuel leaks from the hydraulic cabinet into the UDC and meets the intent of the law. So it is Bravo’s opinion that…
A) The likelihood of the fuel lines leaking from anywhere except a threaded connection is low and there should not be any such points between a primary connection within the hydraulic cabinet and the point that it transitions to the hose on the exterior.
B) Any leaks that might occur from the threads of these lines are going to follow gravity down the path of least resistance – all while evaporating – and if any liquid actually does run down the line into the hydraulic cabinet area it is collected by our Dispenser Conversion Frame (DCF – CONV-B2000). Leaks are not likely to fall from the pipe line within the vapor panel area.
C) By providing a capture mechanism in the vapor panel that directs potentially falling fuel into the UDC we would be bypassing the established and proven function of the water-splash lip by creating a point where water can be captured as well, increasing the risk of water accumulation and false alarms. We seek to first maintain our decades-old reputation of maintaining regulatory compliance in the pursuit of environmental and human safety. But this includes helping our customers avoid unnecessary and potentially costly false alarms.
D) There should be no requirement for Retroactive modifications. Simply put, Bravo does not condone or seek to bring about additional mandatory costs to our customers unless the environment or human health is at risk. In this case we do not consider the vapor panel area of dispensers to pose any threat to either.
FOR CALIFORNIA: State law prohibits anything that increases false alarms due to water intrusion and such alarms can result in full station shut-down which is directly associated with a loss of revenue.
BET YOU DIDN’T KNOW: The Bravo Dispenser Conversion Frame was first launched in 1991, some 16 years before the State of CA made a UDSCCS (Under Dispenser Secondary Containment or Control System) mandatory for dissimilar dispenser upgrades/change outs. We hope you didn’t think that our product was simply built to comply with the 2007 mandate.

Yes. Bravo permits this in any State if the following conditions are met:
> The sump must be installed by a DoubleWall Certified Bravo Installer.
> The sump wall may not be modified in any way or opened to the air.
> Only F-Series-D “full body” entry fittings for DoubleWall sumps may be used.
The integrity of the sump interstice must remain uncompromised so that it is ready for monitoring at any future time.
Testing and Maintenance Guidelines:
DoubleWall sumps intended to be used as SingleWall sumps must be installed and tested per each product’s respective installation manual, with the exception of liquid filling and the Advanced Leak Detection Procedure (ALDP) that follows it. (Sump interstice must remain dry until monitoring is required)
They may be water tested per local regulations. Note the frequency of water testing sumps varies per State or county. E.g. California’s SB-989 guidelines require water testing of a SingleWall sump every 3 years. Click Here to download the official Bravo testing guidelines for SingleWall sumps.
When not intended for VPH monitoring, options to test via pressure and vacuum are also permitted.
It is also recommended but not required that a pressure test be conducted periodically to ensure 100% integrity of the sump interstice.
The same goes for vacuum testing though this should only be done before the sump has been backfilled and only if it is completely dry on the exterior, free of any water, mud, etc…
Guidelines for converting Bravo brand Non VPH DoubleWall sump to VPH compliant:
In this case the DoubleWall sump should be pressure and/or vacuum tested per the recommended guidelines found in product installation manuals.
If it is to be Vacuum monitored, factory-approved vacuum components should be installed to facilitate this.
If it is to be Hydrostatically monitored, only Bravo interstitial fluid may be used to fill the sump, the Hydro-Vac filling procedure and subsequent ALDP test must be conducted per each respective products’ installation manual.
Yes. Our adhesives, lamination kits, epoxy kits, all F-Series family fittings for new construction or retrofits, retrofit tank sump covers and tank collars are all permitted to be installed to other manufacturers products. In most cases, all that matters is that our products are being installed to other fiberglass products. Consult all product literature and seek to verify product compatibility with your application.
NOTE: Bravo sumps and entry fittings come with a 30-Year warranty and other manufacturers sumps do not. While there is no immediate benefit from building an entire fuel site using Bravo products (we do not require it for warranty activation, extensions or product discounts), it would be wise to consider the long-term costs involved with using another product. With no paint or gel-coats, it is clear what you are buying when you choose Bravo. In other cases you may be paying more for less. Remember, not all Fiberglass is created equal.
Feel free to call or chat with us anytime and we will advise and assist.
A: The procedures approved by S. Bravo Systems, Inc. for the SB-989 (SingleWall) and AB-2481 (DoubleWall) sump tests are detailed within each products instruction manual. Expanded directions are available in the two documents listed below.
Bravo SingleWall Test Protocols.
Bravo DoubleWall Test Protocols.
Note: Always check with you local regulatory authority for additional guidelines for testing requirements that may be more stringent than those established by S. Bravo Systems, Inc.
A: Frequently, No. Adding fluid frequently should not be necessary. However, monitored DoubleWall systems are subject to various and varying physical and environmental conditions as outlined below. When these conditions are present, periodic observation and maintenance may be required, which may include topping off the interstitial fluid. The majority of these false-alarms happen in the Fall and Spring during seasonal temperature shifts.
It is recommended that a maintenance program be established to support the integrity, cleanliness and function of a containment system at any fuel site in an effort to proactively protect the environment from contamination. Each and every alarm caused by a fluid level drop should be evaluated and monitored. Sumps where an alarm occurs more frequently than every 6 months between seasonal shifts should be considered suspect due to a leak. Testing procedures for Bravo DoubleWall sumps as outlined in each respective installation manual should be followed to attempt to pinpoint the cause of a potential loss of interstitial fluid. This testing should be conducted only by a Bravo Systems DoubleWall-Certified individual or company.
NOTE: Repairs on sumps with major damage that constitutes a containment breach of any material component below grade are not allowed unless Bravo Systems Technical Support has been contacted, the situation is evaluated and a Letter of Authorization is provided on company letterhead detailing the specific issues and remedy’s.
If there is a drop in the fluid level to the point where an alarm is generated, you have one or more of a few common issues.
A) You have a breach. Most commonly a leak is caused by a Flexible entry fitting. This could also be caused by impact damage to the interior or exterior sump wall. Impact damage or bruising on Bravo Systems sumps may be visually identified by a concentration or spider-web of white color in the fiberglass. This is true for Bravo sumps that are a natural color on the interior. Our sumps have been paint and gel-coat free since mid 2006.
B) You have air in the interstice, and it is either a) Expansion and contraction of the liquid, expansion and contraction of the air trapped in the liquid, air in the system expanding within the propylene glycol during hot weather causing the fluid to spill out of the manometer, causing an alarm when the temperature drops and the fluid level falls. Alarms that frequently occur at night time or early morning hours are usually attributed to a fall in brine level due to a temperature drop and may happen because the level was already low. Most alarms due to fluid level fluctuations occur at night, and the majority of these types of false-alarms happen in the Fall and Spring during seasonal temperature shifts. and/or b) A DoubleWall sump that was not filled with interstitial fluid per our mandatory Vacuum-Hydrostatic filling procedure is burping air from being “gravity-fed” the fluid. After gravity-feeding fluid into an interstice it can take weeks or months for air to gurgle out of a sump through either the primary or atmospheric manometers.
C) Localized environmental and/or weather conditions may cause the interstitial fluid to evaporate at a more noticeable rate than other areas. In this case, you should determine whether the liquid loss is recent or if it has been occurring over a long period of time.
D) There also exists an issue with some Tank Sumps where the lack of an atmospheric manometer to equalize sump interstice pressures exacerbates the chance of a false alarm and/or fluid spillage. To minimize these alarms, you can install our new low-profile atmospheric manometer for the B400 Series DoubleWall tank sumps. It’s part number is “ATM-400-LP” and can be easily installed into the test port opposite the manometer to assist in equalizing the sump interstice pressures.
A: Yes and no.
NO: If the DoubleWall sump is continuously monitored via vacuum or hydrostatic fluid per California AB-2481 VPH guidelines, you will void the sump warranty if water tested per SB-989 guidelines.
YES: If the DoubleWall sump is installed and intended to be used only as a “SingleWall” sump, in addition to standard VPH testing procedures during initial installation, SB-989 periodic testing is permitted. In this case the decision is made by environmentally responsible fuel marketers to have sumps installed prior to the need for monitoring, which are capable of being continuously monitored per California AB-2481 guidelines.
Let’s educate ourselves. Download LG Letter 162-1 and browse to Page 6, to the latter of Part II: Section A.
The paragraph reads:
Pursuant to Section 2637(a)(6) of Title 23, CCR, portions of the UST system which are continuously monitored using vacuum, pressure, or interstitial liquid level measurement methods are exempt from periodic secondary containment testing. Therefore, periodic secondary containment testing is not required for secondary containment of tank and piping that are continuously monitored using vacuum, pressure, or interstitial liquid level measurement methods. Please note that annual certification of the leak detection equipment is still required.
Assembly Bill 2481 is specific to the State of California. These high standards far exceed the level of containment provided by the SB-989 standards.
As far as testing is concerned, testing per SB-989 is only valid for SingleWall sumps. It is not a practical test method for DoubleWall sumps which are already continuously monitored.
1) Sump ships from factory sealed under a continuous Vacuum test of 20″+ Hg.
2) Any breach in the wall, after sealed (Eg. penetration fittings, lamination) is pressure/soap tested at 4 psi.
3) A 4 psi air integrity test is conducted after all laminations / fittings have been installed (prior to any hydrostatic filling) for one hour to allow the pressurized interstice to acclimate, then level is recorded, and tested for another hour before recording result.
4) We also recommend that when DoubleWall sumps are left overnight, that they have a factory-level vacuum (20″+ Hg) applied to the interstice, so that they can be inspected the next day.
5) If the sump is to be hydrostatically monitored, it is Hydro-Vac Filled. This is a Bravo-Exclusive installation procedure that pulls a 20″+ Hg vacuum on the interstice, then allows the interstitial fluid to flow in from a multi-gallon source through a ball valve. That isn’t a test! You’re right. The Advanced Leak Detection Procedure (ALDP) depends on the sump being filled with our interstitial fluid first. The ALDP test pulls a high vacuum on the interstice after it has been filled with liquid. With no acclimation necessary, the inspection can be done right after the Hydro-Vac filling process. Any leaks in the DoubleWall sump will show up as trails of bubbles coming directly from the leak point(s), which can then be located and repaired without wasting time guessing.
Bravo Systems has been producing DoubleWall Containment sumps since August 2003 and has continued to be the Leader in reliable Secondary Containment equipment. Realizing that the last point of failure were the varied models of flexible penetration fittings, Bravo Systems engineered an entire line of Tank-Spec Fiberglass Fittings (F-Series) that allow you to install and forget while being compliant at the highest level. The F-Series provides unquestionable peace of mind as the fittings cannot deteriorate or fail since they contain no plastics, rubber, nuts/bolts, metals and do not need to be filled with caulks or mechanical sealants. We are also the only manufacturer that provides an all-fiberglass conduit penetration fitting. Take a look at our line of all-fiberglass fittings from the Products navigator at the top of the page.
A: No. It is not required as long as the installer, maintenance and / or repair technician follows the directions contained in our latest Installation Manuals. The most current Installation Manual from our website must be printed and used. See Installation Manuals here. Make sure that you have your paperwork in order and records are kept. Have the owner or other authority sign and date the Installation Manual that you download from our website. The most important things to know are these:
1) There can be no debris within the float cup so as to impede the travel or function of the float. Debris and dirt should also be removed from the entire containment sump so that none re-enters the float cup(s).
2) After connecting the ball chain to the shear valve retainer, testing the poppet shutoff must only be done by adding liquid (typically water) to the cup until it trips (remove all liquids after this test). You must never test this mechanism by physically pulling the float stem, arm or chain because you bypass the intended function of the float.
3) If the float does not rise or trip the shear valve when water is added to the float cup, ensure that the travel is unimpeded by debris or dirt. If the float has been broken in any way and allows fuel and or water to enter it, then it will not trip the shear valve poppet. To determine whether the float cup has been breached, trip shear valve poppet so you can physically pull the float up into the highest position. You should then have adequate room to shake the float and see if it feels/sounds like there is any liquid inside it. If it has any liquid in it, the float may be breached and a Bravo “FA-KIT” should be ordered which will require the overall float arm length. Please contact Bravo with any questions at (800)-AT-BRAVO.
The purpose of the Bravo Float Trip Mechanism is to minimize the amount of fuel needed to trip the shear valve and to maximize the amount of time a maintenance crew will have to get to the sump in question to repair it.
However, Bravo Systems recommends that the National Certification Test (primarily for SingleWall products) be completed by technicians in the field because it covers the installation and repair of our SingleWall product lines that feature Float Trip Mechanisms, but also requires the individual read through the Instruction Manuals, helping to educate and familiarize them with the products.
A: Yes. For each DoubleWall product, Bravo interstitial fluid is provided, with 1/2 to 1 gallon extra.
A: Yes. There is a monitoring manometer and an atmospheric manometer. Manometer = Fluid Reservoir. All accessories for the continuous monitoring and testing are installed. All Bravo DoubleWall sumps ship under a continuous 20″ Hg vacuum test. The larger of the two is used for visual inspection of fluid level and is the unit that a float-style electronic level sensor is installed in, when required. The atmospheric manometer is used to help balance the fluid level within the sump.
A: No. Bravo Systems Highly Recommends its B1 Vapor Shear Valve which is both UL and CARB Approved. Most Bravo UDC sumps also do not include the vapor shear valve stabilizer bracket.
FOR BRAVO-CERTIFIED CONTRACTORS / INSTALLERS ONLY:
When your Bravo products arrive via freight, inspect all components for visible damage. If there is any, record the damage on the bill of lading in detail and call Bravo Systems with your damage report details.
If the gauge appears to be damaged, call Bravo Systems to obtain replacements free of charge.
You need to verify if the leak is happening at the gauge assembly or the sump. Common procedure is as follows:
1. Pressurize the interstice to no more than 4 PSI max.
2. Submerge the entire Vacuum gauge assembly under water, such as a bucket or pail. Look for signs of air leaking.
3. Pressure / soap test each length of tubing and each test port at the sump wall.
4. If these tests are inconclusive, leave the suspect sumps overnight under 20″ Hg vacuum and observe gauges in the morning.
5. If your sumps held vacuum, proceed with the installation per the products respective Installation Manual. View them HERE.
6. If your sumps did not hold vacuum, call Bravo systems with the results of your testing so we can better help you.
If you are shipped replacement gauges: After you install them per the provided instructions, follow the overnight vacuum test outlined in # 4 above to conduct a factory test of a re-sealed interstice.
For B-18-3 Black Plastic Compression fittings leaking between gasket and pipe. Use WR-3 wrench to loosen seal between nut and donut gasket. Apply wet-dry grease between nut and gasket to allow nut to easily make a compression seal. If you cannot get grease between nut and gasket spray WD-40 between surfaces to lubricate hard to reach areas. Then compress nut to 1/4 to 1/2 turns past hand tight. If the bottom gasket seal of the B-18-3 black plastic compression fitting is leaking, the new (2014) Bravo B2000 Retrofit Kit includes a component to seal these as well as all other entries. Read below.
For Electrical or Vapor entries that do not have a seal or are leaking. Bravo has designed and packaged a “Kit” that includes Bravo Retrofit Epoxy along with custom FRP clamshells and reducers so that a contractor or service technician can retrofit these entry points to be water and fuel tight. Note that the new “B2000-Retrofit-Kit” should be ordered and installed to every 2000 UDC after appropriate cleanup as a retrofit operation to help ensure regulatory compliance and extend the working life of each UDC. Documentation on this kit can be found on the B2000 product page of this website.
For Shallow Pans with Divider Tabs – Required to electronically monitor each section? You are authorized to remove the liquid divider(s) or a portion of them if they exist. You need only to remove an area of a few inches from each divider to facilitate unrestricted liquid communication between the previously isolated containment zones. Bravo manufactures a composite plug that you need to epoxy into each float cup reservoir OTHER than the lowest point. An electronic sensor should be placed at the bottom of the single remaining float cup reservoir. All reservoirs in a sump should not be plugged. Documentation on this kit can be found on the B2000 product page of this website. Follow this procedure:
1) Remove all mechanical float trip mechanisms and their assemblies.
2) Remove any sealant at the divider area you wish to remove.
3) Using Tin-Snips, snip the divider vertically in two places and remove the loose piece.
4) Seal any metal that was cut, scratched or dinged with Vulkem sealant or PetroSeal to prevent against corrosion.
5) Use some water to determine which float cup reservoir is the lowest one.
6) Remove all liquids from the sump. Clean and dry the sump interior.
7) Lightly sand the float cup reservoirs that need to be sealed and epoxy the Bravo B2000-PLUG into them.
8) Install the sensor to the lowest point float reservoir.
Since a single cup would be left, any and all water can collect there even in amounts small enough to not trip the float so in most cases it is recommended to proactively convert that single cup to Fiberglass. The FAQ question below covers this.
What if there is only corrosion / rusting on or within the float cup reservoir?
This Q/A goes in hand with the use of PLUGS mentioned above to seal off float cups for electronic monitoring. Since a single cup would be left, any and all water can collect there even in amounts small enough to not trip the float. If the float cup reservoir shows signs of rusting through at any point below the floor of the shallow pan, the item number “FLOAT-CUP-RETROFIT-KIT” can be installed to retrofit a fiberglass float cup to the UDC so that it’s secondary containment integrity can be restored. Being a low point where water usually collects, converting float cup reservoirs to fiberglass via this retrofit kit also very effectively prolongs the working life of the UDC. Bravo is proud to still have these steel shallow pans in compliant operation today decades after installation even without these modern retrofits. Documentation on this kit can be found on the B2000 product page of this website.
How can I clean up a dirty B2000 or address evidence of surface corrosion? Follow this procedure:
A) Dust, blow out and/or vacuum any dry debris from the interior.
B) Vacuum out any liquids, debris, gunk, etc..
C) Protect any exposed test ports or threads, remove any electronic sensors.
D) Use Acetone to clean the surfaces so a visual inspection can be made.
E) Scrape the bottom and/or walls with a flat-blade tool. Re-vacuum.
F) Lightly sand all areas where the factory epoxy-paint is missing.
G) Coat any exposed steel with AmerShield, overlapping remaining factory paint.
What about corrosion on the exterior of the B2000 shallow pan?
Since exposing the underside and/or sides of the B2000 sump is rare, It is recommended that all exposed steel on the exterior is cleaned, sanded and proactively coated only with AmerShield as a corrosion barrier. Follow the same instructions as in Steps D, E and F above except on the exterior. Apply at least one coating of AmerShield and keep it exposed to the open air until it has fully cured.
How do I seal a hole in a B2000 shallow pan?
This fix does not apply to a hole caused by corrosion. You are prohibited from re-sealing a structurally weakened and/or mostly-corroded steel wall or floor with fiberglass. For factory or field-cut holes where an entry fitting was removed or abandoned you must re-seal the bottom floor of the sump. Bravo considers even a hole placed accidentally and forgotten to be the same as a factory cut hole. Both factory-approved methods described below require full pre-cleaning. Step 1 requires only cleaning while Step 2 requires the surface preparation and sanding steps as well. There are two options:
1) Re-install the original Bravo OEM fitting with a capped pipe. The pipe and cap must be liquid tight and should be tagged or labeled that it is NOT a fuel line or connected to a tank.
2) Install a Bravo FRP plate to the floor. For this procedure, Bravo supplies retrofit epoxy for sealing / gap-filling and a 10″x10″ plate which must be dry-fit and trimmed to fit over the hole. The following requirements apply: Minimum 3/4″ of contact with the steel floor 360° degrees around the opening. 1/2″ of clearance between the FRP plate and any other object, e.g., entry fittings, float cups, their hardware, dividing louvers. The plate edge should be beaded with epoxy and any steel still exposed near the repair should be coated with the same epoxy as a corrosion barrier. The patch should NOT be painted after installation so that it can be identified at a later time as an official Bravo repair.

GENERAL GUIDELINE: No exposed Steel. No electric power tools OR sparking tools.
If a UDC has rusted through on the bottom of the pan or a vertical wall, it must be replaced. There is no authorized repair procedure and the structure of the UDC may be weakened to the point where a drive-off or collision may endanger customers on the forecourt and/or be the cause of unnecessary property damage.
Note: Always check with you local regulatory authority for additional guidelines and permitting requirements.
A: No. Under no circumstances can you modify, repair or add to a Bravo Systems Dispenser Conversion Frame (CONV-B2000) unless authorized in writing by the factory.
When a situation exists where there may be piping or conduit interference with a conversion frame, you must contact Bravo immediately to begin factory evaluation. You must provide images of the issue areas to Bravo so that engineering staff can review your specific application and provide guidance, installation directions, materials and written authorization. This authorization from the manufacturer (Bravo) is required in California, per CA SWRCB approval of the CONV-B2000 conversion frame as a UDSCCS (Under Dispenser Spill Containment or Control System).
If this process is conducted on a site without proof of written authorization from Bravo in the state of California, that installation is non-compliant and should be addressed and/or replaced per all local codes, regulations or applicable laws.
This product can be found on the Conversion Frame Page.
A: This is answered in part in another FAQ.
Click here to view how Bravo is “Built Like a Tank!”
A: Absolutely. We understand there may be some concerns about corrosion due to short or long-term DEF exposure, so we openly certify that our products are compatible with and approved for use in secondarily containing DEF.
Note that Bravo does not manufacture any products built for primary containment. We are a secondary containment specialist only. When DEF fluid leaks into our sumps, you likely won’t be collecting it to put back into the tanks/totes so maintaining the quality when being secondarily contained is pointless. But since we certify 100% compatibility, Bravo sumps won’t be corroding or failing on your watch when exposed to DEF for any length of time.
Click on this link to read about how Bravo products are compatible with alternative fuels, along with some other resources.
A: At Bravo Systems, we meticulously engineer our products to be built right the first time. To do this for our UDC Sumps, Transition Sumps, Tank Sumps, Spill Buckets and extensive line of Fiberglass Penetration Fittings we looked to the highest standard, Tanks. Since the Tank is the primary fuel vessel meant for long-term storage, we studied it’s specifications ( UL Spec 1316 ) and built our Fiberglass products to match them. Unlike other similar products out there, our choice of materials and quality of design stands up to the test of years of use. In this way we have designed our products to last the life of your station, as the Tank is meant to. Simply put, anything a fiberglass tank can store… our fiberglass products can store as well, for the same duration, under the same conditions. Bravo Systems’ Single and Double Wall Secondary Containment systems truly are Built like a Tank.

S. Bravo Systems Fiberglass Products are UL Listed to be compatible with all alcohol blends. UL Certifications / proof of listing can be found on each applicable product’s webpage in the documents area.
A: Bravo has custom made products since its inception in 1987. Take a look at any catalog and if you see the general profile of what you need, but need different dimensions, just let us know. Our Custom products are shown on our Custom Page. You can also email Bravo at email@example.com to discuss solutions for your specific needs.View More
A: No. Our glycol is a light red color and is the only fluid allowed in our sump walls primarily to assist with troubleshooting and identification in the field. The exception is water if the sump must be emptied of glycol and flushed clean but water or colored water may not be used for continuous monitoring within our sump interstice. Additionally, other manufacturers may add other chemicals or inhibitors to their fluid in different concentrations which we do not test for or certify.View More
A: NO! Bravo Systems allows only our own Propylene Glycol solution as an interstitial fluid. Using a brine solution or colored water will void your product warranty. The very idea of using brine as an interstice fluid was thrown out by Bravo for use in Double Wall sumps because brine would potentially accelerate deterioration of steel/stainless steel components that come into indirect and direct contact with the brine. This includes penetration fasteners, bolts, flex-connectors and band clamps. Propylene Glycol helps prevent the liquid from freezing within the interstice. Additionally, if the brine solution were to leak out of the wall it could also accelerate the corrosion of other metallic components within the sump.View More
A: Click on this link to find technical reference: Propylene Glycol Used in moisturizers for medicines, carrier for fragrance oils, food grade antifreeze, hand sanitizers, antibacterial lotions, saline solutions, cosmetics products, baby wipes, bubble bath solutions, shampoos, paint balls, and air craft deicing fluids. Bravo uses Propylene Glycol as a interstitial fluid for its double wall hydrostatic sumps. Bravo chose Propylene Glycol for its freeze-resistant, non-corrosive and non-toxic properties. You can also request the Bravo interstitial fluid MSDS from our Contact Page.View More
A: Yes one can change Bravo sumps from hydrostatic to vacuum however you must always check with your local regulatory authorities and sensor manufacturer before changing a Double Wall monitoring device. Also consult with Bravo for further recommendations. If you have a vacuum sump, some installation will be required to make your sump hydrostatic ready.View More
A: Yes and no.
Yes. The F-Series fitting for fiberglass pipe is compatible with Brine or salt water (water and sodium chloride) since the fitting does not consist of any metal components. However, sodium chloride is not allowed in Bravo Systems DoubleWall Sumps, and will void the warranty of that containment sump.
No. It is not permitted to use an F-Series fitting for galvanized conduit on another manufacturer’s sump which is filled with Brine / saltwater. The condition, as listed in our product literature is that you must use RobRoy brand PVC coated conduit in conjunction with our conduit entry fittings. Note that no other brand of PVC coated conduit is permitted, such as Ocal Blue.
NOTE: Nomenclature varies throughout the Nation so someone may refer to the liquid in a DoubleWall sump or Tank as “Brine” because that is what it has been called for decades. Bravo Systems permits only Propylene Glycol (a non-toxic, food-grade antifreeze) since it will not corrode metallic components. So two common reasons are: No corrosion of bolts if flexible entry boots are installed to a sump, and no additional corrosion of metallic components if brine leaks or is spilled into the sump interior. If someone tells you the DoubleWall sump is “brine filled”, just be sure to check which type of fluid they are referring to.
A: NO. The EBS and B-27 fittings are bulkhead-style fittings made only for steel walled product lines and can not be installed to fiberglass sump walls.
The EBS conduit bulkhead fitting applies primarily to the B-8600 above ground UDC and the B500/600 series transition sumps.
The B-27 legacy fitting was designed only for the B-2000 shallow pan (Bravo Box) but was sometimes used on the B-8600 for specific applications.
Only flexible rubber entries or Bravo all-fiberglass entries can be used on our Fiberglass sump walls, whether SingleWall or DoubleWall. Bravo highly recommends that flexible entries are not used in below-ground piping systems. To enforce this recommendation, Bravo has developed all-fiberglass entry fittings for conduit and product piping. See the FAQ below for F-Series conduit fittings or visit the F-Series page to view all fittings.
A: Specific types of conduit are mentioned in the F-Series & FF-Series Instruction manuals.
The chart below is primarily for F-Series models. FF-Series fittings accommodate both the galvanized and PVC-coated versions of conduit for each size. Consult product literature for more information.
NOTICE: As of January 1, 2014: OCAL Blue brand conduit manufactured by Thomas & Betts is permitted to be installed together with any supporting model entry fitting in the F-Series family. This includes retrofit fittings. Any OCAL conduit manufactured before this date must have it’s jacket stripped back at the bonding point and a Retrofit fitting bonded directly to surface-prepped steel.

A: Yes. We have solutions for these. When a flexible entry fitting fails, the fitting must be replaced or retrofit with another. The failed fitting is commonly replaced again with a similar type of fitting. Replacing a failure-prone component in a fuel system with another is not sustainable for anyone. No amount of filling, or external adhesive application will ever permanently repair the offending fitting.
Your options for Bravo entry fittings:
For Bravo DoubleWall Flexible fittings: (F-17-D, B-32-D, B-33-D) If the failed component is on the inside, this can be replaced from the inside. Re-order the same part number. However, you cannot be sure that A) the exterior half of this fitting has not failed as well, and B) that it will not fail in the future. We strongly recommend a Fiberglass Retrofit instead, see below.
For Bravo SingleWall Flexible fittings: (F-17, B-32, B-33, B-34) This boot was engineered to be replaced from the inside. Re-order the same part number. However, we strongly recommend a Fiberglass Retrofit instead, see below.
Your options for other manufacturers entry fittings:
For SingleWall Fiberglass Sumps: The F-Series Retrofit-S line of split retrofit fiberglass fittings replace your existing rubber fittings whether they are failing or not and without the need to break concrete. These split fittings are ideal for permanently sealing your sump wall to your fiberglass piping in the event of flexible fitting failure, or for pre-emptive flexible fitting replacement.
For DoubleWall Fiberglass Sumps: The F-Series Retrofit-SD-AB line of split retrofit fiberglass fittings replace your existing rubber fittings whether they are failing or not. These fittings are double-ended split versions of the SingleWall Retrofit fittings and do require you to gain access to the exterior of the sump for each flexible fitting you are replacing.
Another option is the F-Series D-BLR-S line of split retrofit fiberglass fittings which are fully AB-2481 compliant. This model does not require you to break concrete but it does require a Specialist installer. This split fitting voids the half of the flexible fitting on the exterior of the sump and offsets the interstice of the sump inwards, maintaining fluid communication to the surface of the conduit or the secondary pipe.
