Incorrectly Sized Pump

Selecting the right size pump is very important. Bigger is not necessarily better. If a pump is too large, the pump will cycle on and off more than it needs to, which can result in a shorter pump life. If the pump is too small, it may not be able to pump the water out or it will run too long and too hot, shortening the pump’s life.

The installer of the drain system should size the pump based on the calculated amount of water needed to be pumped (called capacity and indicated in gallons per minute) and the height and length the water needs to be pumped (head). Ask the installer for their calculations and a copy of the pump capacity chart.

If the installer cannot produce these calculations, this indicates a problem. Ask the installer to put you in touch with technical support at the pump manufacturer.
