Pump & Suction

Stay off the main drain!

Your circulating pump creates a strong vacuum at the main drain at the bottom of your pool. In fact the suction is so strong, it can trap adults or children


We recommend removal of the automatic pool cleaner when swimming. Read the cleaner or vacuum owner’s manual for safe operating information.

Make sure your pool or spa has the following:

  • An emergency shut-off switch for the pool circulation pump

  • and the spa jet pump 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.

  • At least two suction outlets from the pool to the main

  • circulating pump.

  • Either one of these outlets should be able to supply the

  • pump by itself without exceeding the flow rating of its cover.

  • (Many aboveground pools use the skimmer as the suction outlet,

  • and have no main drain;

  • these pools don’t require a second suction outlet.)

  • Each outlet must have a cover fastened down with screws,

  • be designed so that they won’t trap body parts or hair, and 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.
