Pumps are the muscle of your pool system pushing water through the skimmer, piping and plumbing, filter and all the rest of the equipment.

Ranging anywhere from 1/2 to 3 horsepower or more, pumps vary is size, shape, color, and manufacturer but they perform the same basic function. They have a motor which turns an impeller which draws the water into the pump pot, through the basket, then sends the water up into the filter, which then goes back into the pool. Just before it flows into the pump, the water passes through a metal strainer basket that catches leaves and other large debris that might clog up the pump.

Make sure your pump pot is full of water at all times while the motor is running. If it runs out of water, even for a few minutes, it could warp the plastic pieces (impeller, seal plate, basic - even the pump pot itself). If the pump runs too long without water, even the motor can burn out, requiring a complete replacement.

If your pump is making a strange, loud, or whining noise, consult your local service technician for repairs.
