TO MINIMIZE THE RISK OF INJURY DUE TO SUCTION ENTRAPMENT HAZARD:
Pools and spas should utilize a minimum of two drains per pump.
A properly installed and secured ANSI/ASME A112.19.8 approved anti-entrapment suction
cover must be used for each drain.
Each suction cover must be installed at least three (3') feet apart, as measured from the
nearest point to nearest point.
Regularly inspect all covers for cracks, damage and advanced weathering.
If a cover becomes loose, cracked, damaged, broken or is missing, close the pool or spa
immediately, shut off the pump, post a notice and keep the pool or spa closed until an
appropriate certified cover is properly installed.
Replace drain covers as necessary. Drain covers deteriorate over time due to exposure to
sunlight, pool chemicals and weather.
Avoid getting hair, limbs or body in close proximity to any suction cover, pool drain or outlet.
Use a safety vacuum release system ("SVRS"), suction limiting system or automatic pump
shut-off system.
Disable suction outlets or reconfigure into return inlets.
A clearly labeled emergency shut-off switch for the pool pump and spa jet pump must be in an easily
accessible, obvious place near the pool or spa. Make sure bathers know where it is and how to use it in case
of emergency.
The Virginia Graeme Baker (VGB) Pool and Spa Safety Act creates new requirements for owners and operators of commercial swimming
pools and spas.
Commercial pools or spas constructed on or after December 19, 2008, shall utilize:
(A) A multiple main drain system without isolation capability with suction outlet covers that meet ASME/ANSI A112.19.8a Suction Fittings
for Use in Swimming Pools, Wading Pools, Spas, and Hot Tubs and either:
(i)
A safety vacuum release system (SVRS) meeting ASME/ANSI A112.19.17 Manufactured Safety Vacuum Release systems (SVRS)
for Residential and Commercial Swimming Pool, Spa, Hot Tub, and Wading Pool Suction Systems and/or ASTM F2387 Standard
Specification for Manufactured Safety Vacuum Release Systems (SVRS) for Swimming pools, Spas and Hot Tubs or
(ii) A properly designed and tested suction-limiting vent system or
(iii) An automatic pump shut-off system.
Commercial pools and spas constructed prior to December 19, 2008, with a single submerged suction outlet shall use a suction outlet cover that
meets ASME/ANSI A112.19.8a and either:
(A) A SVRS meeting ASME/ANSI A112.19.17 and/or ASTM F2387, or
(B) A properly designed and tested suction-limiting vent system, or
(C) An automatic pump shut-off system, or
(D) Disabled submerged outlets, or
(E) Suction outlets shall be reconfigured into return inlets.
HAZARDOUS PRESSURE: STAND CLEAR OF PUMP AND FILTER DURING START-UP
Pool and spa circulation systems operate under high pressure. When any part of the circulating system (i.e.
lock ring, pump, filter, valves, etc.) is serviced, air can enter the system and become pressurized.
Pressurized air can cause the pump housing cover filter lid and valves to violently separate which can result in
severe personal injury or death. Filter tank lid and strainer cover must be properly secured to prevent violent
separation. Stand clear of all circulation system equipment when turning on or starting up pump.
CAUTION!: Electrical controls such as on/off switches, timers, and control systems, etc. should be properly
installed to allow the operation (start-up, shut-down, or servicing) of any pump or filter without requiring the user
to place any portion of his/her body over or near the pump strainer lid or filter lid. Such installation should allow
the user to stand clear of the filter and pump during system start-up, shut down or servicing of the system.
Before servicing pool and spa equipment, make note of the filter pressure. Be sure that all controls are set to
ensure the system cannot inadvertently start during service. Turn off all power to the pump. IMPORTANT:
Place filter manual air relief valve in the open position and wait for all pressure in the system to be
relieved.
Before starting the system, fully open the manual air relief valve and place all system valves in the "open"
position to allow water to flow freely from the pool and spa back to the pool or spa. Stand clear of all pool and
spa equipment and start the pump. IMPORTANT: Do not close filter manual air relief valve until all
pressure has been discharged from the valve and a steady stream of water appears. Observe filter
pressure gauge and be sure it is not higher than the pre-service condition.
