1.2 Pool Pump Suction Entrapment Prevention Guidelines
Pump suction is hazardous and can trap and drown or disembowel bathers. Do not use or operate
swimming 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)assemblies
