Closed Bottom Double Wall

The octagon-shaped closed bottom doublewall tank sump is ideally configured for piping laid out in 45- and 90-degree angles. It is field height adjustable and features a pour channel that makes for a simple PC slurry pour joining the sump base and top hat. It comes standard with a snap-lock lid with vertical O-ring seal to make it watertight with other lid options available. It is VPH compliant and can be used as a transition sump or be riser adaptor mounted outside of California. It ships under 20” HG vacuum to ensure wall integrity.
