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) covers must be maintained. Drain covers must be listed/certified 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 - When outlets are small enough to be blocked by a person, 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 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.
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 version 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. 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 version 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.
Testing and Certification - Suction outlet 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 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 which could cause an air trap.
Pool cleaner suction fittings must conform to applicable International Association of Plumbing and Mechanical
Officials (IAPMO
®
) standards.
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.
