How do I perform a hydrostatic test of a containment sump?
Request written instructions from the manufacturer of the containment sump. If there are no written instructions, perform the hydrostatic test described in Petroleum Equipment Institute Recommended Practice 100 PEI/RP100, Recommended Practice for Installation of Underground Liquid Storage Systems. A copy can be obtained from PEI, PO Box 2380, Tulsa, OK 74101-2380.
