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:
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.
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.
