Maintenance
. The pump must be kept clean and free of debris.
. The inlet screen prevents the passage of dirt and other solid material from entering
the pump, but it can become overwhelmed.
. Cleanings should occur often for pumps that run constantly.
. Inspectors should make sure that the float is not tangled or jammed in one position.
. A sump pump with a jammed float is useless because it will not sense when it
should turn on and shut off.
. The pump can be tested by pouring water into the pit to make sure it becomes
activated and expels the water.
. The homeowner should seek professional assistance if the pump does not activate.
. Maintenance should take place annually, and when the home is sold.
. When testing the pump, no one should ever reach into the pit. The float can be
reached and manipulated with a household item such as a golf club (with a rubber
handle) or anything else non-conductive that happens to be lying around.
