Tall Collar Double Wall

The octagon-shaped Tall Collar Double Wall Tank Sump is ideally configured for piping laid out in 45- and 90-degree angles. It comes standard with a snap-lock lid with imbedded O-ring seal to make it watertight. There are 36-inch and Twist-Lock lid options. The base can be mounted to an octagon Bravo double wall collar or directly to a fiberglass or fiberglass covered tank. The sump is VPH compliant. The top-hat ships under 20” HG vacuum to ensure wall integrity. Sumps can be monitored by either Vacuum, Liquid, and Dri interstitial monitoring. ​
