1.2 Pool Pump Suction Entrapment Prevention Guidelines
WARNING
Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use or operate swim-
ming pools, spa, or hot tubs if a suction outlet cover is missing, broken, or loose. The following guidelines
provide information for pump installation that minimizes the risk of injury to users of pools, spas, and hot tubs:
Entrapment Protection - The pump suction system must provide protection against the hazards of suction
entrapment.
Suction Outlet Covers - All suction outlets must have correctly installed, screw-fastened covers in place. All
suctionoutlet(drain)assembliesandtheircoversmustbeproperlymaintained.Suctionoutlets(drain)assem-
bliesandtheircoversmustbelisted/certiedtothelatestversionofANSI

Testing and Certication - Suction outlet assemblies and their covers must have been tested by a nationally
recognized testing laboratory and found to comply with the latest version of ANSI/ASME A112.19.8 or its succes-
sor standard, ANSI/APSP-16, the standard for Suction Fittings For Use in Swimming Pools, Wading Pools, Spas,
