Piping Sumps Model P. 42-2213, PS 42-3013, SPS-+2-22A, and SPS 42-30A As the bolts are tightened,the T-nut will permanently imbed itself in the F 1 a General fiberglass manway flange.A surface-mounted piping sump will prevent future access to the tank from the manway. - The piping sump provides containment of a submersible pump leak and also provides a termination point for double-wall piping systems. The piping sump is produced in two pieces:a lop half and bottom half. F6.
