pool pump suction Entrapment prevention guidelines

sUCTion haZard. Can cause serious injury or death. do not use this pump for
wading pools, shallow pools or spas containing bottom drains, unless the pump is
connected to at least two (2) functioning suction outlets.
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
suction outlet (drain) covers must be maintained. Drain covers must be listed/certified to the latest published
version of ANSI/ASME A112.19.8. They must be replaced if cracked, broken, or missing.
number of suction outlets per pump - Provide at least two (2) main drains, with covers, as suction outlets for
each circulating pump suction line. The centers of the main drains (suction outlets) on any one (1) suction line
must be at least 3 feet apart, center to center. See Figure 1 on page 7.
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) main drains run into a single suction line, the single suction line may be
equipped with a valve that will shut off both main drains 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 on page 7.
More than one (1) pump 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 fitting or cover for any suction outlet must be
1.5 feet per second, unless the outlet complies with the latest published version edition of ANSI/ASME A112.19.8,
the standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs, and Whirlpool Bathtub
Applications. In any case, do not exceed the suction fitting's maximum designed flow rate.
If 100% of the pump's flow comes from the main drain system, the maximum water velocity in the pump suction
hydraulic system must be six (6) feet per second, or less even if one (1) main drain (suction outlet) is completely
blocked. The flow through the remaining main drain(s) must comply with the latest published edition of ANSI/
ASME A112.19.8, the standard for Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs, and
Whirlpool Bathtub Applications.
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, the standard for
Suction Fittings For Use in Swimming and Wading Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.
Fittings - Fittings restrict flow; for best efficiency use the 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.
