A sump pump is an essential piece of equipment for homes with basements. Most homes in high-rainfall areas have one. The sump sits inside a small pit dug out from the basement floor. Groundwater rising under the floor during prolonged rainfall collects in the pit. The sump springs into action, triggered by its internal float. The main drain takes pumped groundwater away, preventing the basement from flooding. Pits are usually covered to prevent radon gas emission. Covering it would also prevent small children, pets and debris falling in with the latter causing a blockage.
Sealing the Sump
Unplug the sump pump and then cut the discharge pipe with the saw.
Put the cover over the pipe and tuck under the liner, which may need trimming.
Apply the suitable silicone sealant over the plate covered by the liner. Smooth the liner over the plate so that it binds together.
Preparing the Cover
Calculate where the outlet pipe will emerge from the cover. There are three sections to the latter. The first is an observation window forming half of the cover. The other half is solid, making the second section. The last section consists of a main support column.
Measure the diameter of the pipe. Use a hole saw to make a matching hole in the solid part of the cover.
Make a little groove, on one side of the hole, to accommodate the electric cable. Thread the cable through the hole.
Attaching the Cover
Put the solid part of the cover with hole over the severed end of the outlet pipe.
Pull the electric cable through before securing the cover.
Place the cover over the plate and sump pit and, using the screwdriver, secure it.
Apply a quality silicone sealant around the electric cable and outlet pipe. Re-attach the outlet pipe with a rubber coupling.
Plug in and switch on the pump after reconnecting the outlet pipe.
