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, spas, or hot tubs if a suction outlet cover is missing, broken, or loose.
The following guidelines provide information for pump installation that minimizes 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 suction outlet (drain) covers must be properly maintained. They must be replaced if cracked,
broken, or missing. Drain covers must be listed/certified to the latest published edition of ANSI
A112.19.8 or its successor standard, ANSI/APSP-16. The pool must be shut down and bathers must be
restricted from entering the pool until any cracked, broken, or missing drain covers are replaced.
Number of Suction Outlets Per Pump - Provide at least two (2) hydraulically-balanced suction outlets,
with covers, as suction outlets for each circulating pump suction line. The centers of the suction outlets
(suction outlets) on any one (1) suction line must be at least three (3) feet apart, center to center. See
Figure 1.
The system must be built to include at least two (2) suction outlets (drains) connected to the pump
whenever the pump is running. However, if two (2) suction outlets run into a single suction line, the
single suction line may be equipped with a valve that will shut off both suction outlets from the pump.
The system shall be constructed such that it shall not allow for separate or independent shutoff or
isolation of each drain. See Figure 1.
Additional pumps can be connected to a single suction line as long as the requirements above are met.
Water Velocity - The maximum water velocity through the suction outlet assembly and its cover for any
suction outlet must not exceed the suction outlet assembly and its cover's maximum design flow rate.
The suction outlet (drain) assembly and its cover must comply with the latest version of ANSI
A112.19.8, the standard for Suction Fittings For Use in Swimming Pools, Wading Pools, Spas,and Hot
Tubs, or its successor standard, ANSI/ASME APSP-16.
Testing and Certification - Suction outlet covers must have been tested by a nationally recognized
testing laboratory and found to comply with the latest published edition of ANSI/ASME A112.19.8 or
its successor standard, ANSI/APSP-16, the standard for Suction Fittings For Use in Swimming pools,
Wading Pools, Spas, and Hot Tubs.
Fittings - Fittings restrict flow; for best efficiency use fewest possible fittings (but at least two (2) suction
outlets).
Avoid fittings that could cause an air trap.
Pool cleaner suction fittings must conform to applicable International Association of Plumbing and
Mechanical Officials (IAPMO) standards.
