• Check that the outlet pipe is not frozen shut or plugged and that it directs water away from the house. • Check that the pump is plugged in. • Remove the lid (if the sump has one) and use a flashlight to check if the sump is clean. • Check that the pump inlet is not plugged. DISCONNECT POWER WHILE CHECKING & CLEANING • Slowly pour about 5 gallons of water into the sump. Try to simulate the speed that water would normally flow into the sump. • Watch the action of the on/off switch and listen to the pump. • Make the pump turn on and off at least twice. • If something doesn't work right, fix it as soon as possible. |
