Pedestal Sump Pump Cover Guide

The Pedestal Sump Pump Cover was created to address a specific need. Pedestal sump pumps are built to keep your pump out of the water and thus tend to be long-lasting pumps. If you are installing a radon mitigation system you will need to enclose and seal the entire area above the basin. This can present a problem, but there is a solution! Here we will discuss how you can solve this issue without installing a submersible pump and the benefits of our unique sump cover design.

Why Seal Your Pedestal Sump Pump 


The Pedestal Sump Pump Cover is the solution to this problem. Not only does it provide a way of making an airtight seal, but it also allows you to glance into your basin through the clear Lexan cover.

To gain access to your pump you can simply remove the Lexan cover. When installed correctly, you can even remove the sump pump without removing the cover. As a bonus, it will slightly damper the noise of a running pump.

An unsealed sump basin is the source of odors and moisture that can cause problems and make spending time in your basement unpleasant.

Sealing your sump basin is a vital safety feature to keep children and pets from falling into a water-filled sump basin. Some municipalities' building codes require that sump basins be securely covered.

How to Install a Pedestal Sump Pump Cover

Pedestal cover measure

1. Cut your outlet pipe to fit around the cover. The first obstacle is the outlet pipe. By setting the sump cover next to the pipe, you want to mark the pipe level with the cover.

Go down about two inches from your initial mark, that's your cut mark. Those two inches are important so that the pipe can be rejoined below the top of the cover. That way you can remove the coupling in the future if you ever need to replace the pump.

Be sure to unplug your pump before cutting and cover your pump with a plastic bag to protect it from the water that may still be in the pipe. With a hand saw cut until you have water coming out and then use your hand to direct the water spray back into the sump.

2.  Position the sump cover. With the pipe cut you can then position your sump cover into place. Take off the Lexan cover and pull the cords for your pump through the opening so the cover will sit flat on the floor.

Reach inside the cover and mark around the pipe on the inside top of the cover where the pipe will be coming through the cover.

Then mark the outside perimeter of the cover where it sits on the floor. Cut the right hole for your size pipe and cord seal. See this page to determine the correct hole size for your pipe seal.

3. Sealing the cover. Next apply a good sized bead of caulk along the mark on the floor where the cover will sit. We use Radon Pro Sealant which has good adhesion and low VOC’s.

Fit your pipe through the top of the cover, fish your power cord up through the hole and place the cover on the caulk. Make sure to get everything lined up. Put on your pipe seal and cord seal.

Then drill a few holes into the concrete and use concrete screws to secure the cover to keep it from moving. Next use either a rubber coupling or a check valve to reconnect your discharge pipe.

For any hoses that need to drain into your sump you can drill additional holes along the bottom edge of your cover. Use the appropriate size pipe seal for your hose.

Add an extra bead of caulk along the edge of your cover to ensure an airtight seal and then smooth it out.
