A sump pump cover prevents objects from falling into the pump. Local zoning offices often require them. Sump pump covers can be purchased, but there are not covers to fit every type of sump pump. If this is the case, then you may need to make one yourself. Follow these steps to make your own sump pump cover.
Step 1 - Measure
Be sure that you have the exact measurements for your sump pump cover. Either measure the sump pump with a measuring tape or hold plywood over the sump pump and mark the exact size and shape that it will need to be. From there, cut your plywood into the shape and size that it needs to be.
Step 2 - Seal
Seal the plywood to the floor. In order to do so, use a foam-rubber gasket. Seal the plywood around the cover and around the penetrations for the vent pipe, power cord, and discharge pipe.
Step 3 - Vent
The sump pump needs to be vented. In order to do so, use PVC pipe that measures 4-inches in diameter along with a vent stack.
