Hazard #1
Pump suction (from the main circulating pump)
Your pool or spa’s main circulating pump pulls in water by means of a strong vacuum through the main drain. The vacuum is so strong that anyone lying on an 8” diameter main drain while the pump is running could be held down on the drain by a force of up to seven hundred pounds (that’s right, 700 pounds). This is enough force to trap adults or children underwater, or even to eviscerate them. Stay off the main drain! Have your pool professional examine your pool or spa for the following points:
- There must be at least two suction outlets from the pool to the main circulating pump. Each outlet must have a cover fastened down with screws. Either one of these outlets should be able to supply the pump by itself without exceeding the flow rating of its cover. (Many above-ground pools use the skimmer as the suction outlet and have no main drain; these pools don’t require a second suction outlet.) Read the pump owner’s manual for flow requirements for your installation.
- All suction outlet covers (for instance, grates, anti-vortex covers, etc.) must be designed so that they won’t trap body parts or hair, and must be certified by a nationally recognized testing laboratory. Plastic deck and drain covers may deteriorate and crack or break from exposure to sunlight or weather. Routinely replace them every 3-4 years.
- An emergency shut-off switch for the pool circulation pump and the spa jet pump should be in an easily accessible, obvious place near the pool or spa. Bathers should know where it is and how to use it. Use the switch in case of emergency.
- Most pool cleaners and all pool vacuums use the pump suction to clean the pool. Because of the strength of the suction and the possibility of entrapment underwater, keep everyone out of the pool during cleaning or vacuuming. Read
the cleaner or vacuum owner’s manual for safe operating information. Never play with the pool cleaner, the vacuum, or their hoses – they are not toys.
