Is there a repair method for Bravo UniFitting flexible entry fittings? What about other manufacturers entry fittings?

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.
