1.2 Pool Pump Suction Entrapment Prevention Guidelines
WARNING
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.
WARNING
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) assemblies and their covers must be properly maintained. Suction out-
lets (drain) assemblies and their covers must be listed/certied to the latest version of ANSI
®
/ASME
®
A112.19.8 or its successor standard, ANSI/APSP-16. They must be replaced if cracked, broken, or
missing.
• Number of Suction Outlets Per Pump - Provide at least two (2) hydraulically-balanced 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 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) main drains run into a single suction line, the sin-
gle 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.
• 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 outlet assembly and its cover for
any suction outlet must not exceed the suction tting assembly and it’s cover’s maximum design ow
rate. The suction outlet (drain) assembly and its cover must comply with the latest version of ANSI/
ASME A112.19.8, the standard for Suction Fittings For Use in Swimming Pools, Wading Pools, Spas,
and Hot Tubs, or its successor standard, ANSI/APSP-16.
• If 100% of the pump’s ow 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 ow through the remaining main drain(s) must comply with
the latest version of ANSI/ASME A112.19.8, the standard for Suction Fittings For Use in Swimming
Pools, Wading Pools, Spas, and Hot Tubs, or its successor standard, ANSI/APSP-16.
• Testing and Certication - 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, the standard for Suction Fittings For Use in Swimming Pools, Wading Pools, Spas, and
Hot Tubs, or its successor standard, ANSI/APSP-16.
• Fittings - Fittings restrict ow; for best efciency use fewest possible ttings (but at least two (2) suc-
tion outlets).
• Avoid ttings which could cause an air trap.
• Pool cleaner suction ttings must conform to applicable International Association of Plumbing and
Mechanical Ofcials (IAPMO) standards.
