Pump suctions are hazardous and can trap and drown or disembowel bathers. Do not use or operate
pump, pool or spa if a suction outlet cover is missing, broken, or loose. Follow the guidelines below for a
pump installation which minimises risk to users or pools and spas.
Entrapment Protection
The pump suction system must provide protection against hazard of suction entrapment or hair
entrapment/entanglement.
Testing and Certification
Suction outlet covers must have been tested by a nationally recognised testing laboratory and found
to comply with the latest AS1926.3 standard or ASME/ANSI specifi cation for Suction Fittings For Use in
Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.
Outlets Per Pump
Provide at least two hydraulically balanced main drains, with covers, for each swimming pool pump suction
line. The centres of the main drains (suction fittings) must be at least 800mm apart. The system must be
built so that it cannot operate with the pump drawing water from only one main drain (that is, there must
be at least two main drains connected to the pump whenever it is running). However, if two main drains
run into a single suction line, the single suction line may be equipped with a valve which will shut off both
main drains from the pump. More than one pump can be connected to a single suction line as long as the
requirements above are met.
Water Velocity
The maximum water velocity through any suction outlet must comply with the latest AS1926.3 Standard
or ASME/ANSI Specifi cation for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool
Bathtub Applications.
