Sump pump cover for radon mitigation system

What is a radon sump cover?

A Radon Sump cover, as the name suggests is just a lid that covers the sump pits designed for radon mitigation.

Other than preventing the radon gas to build up in your house, it acts as a protector of the sump pit from the unwanted objects that may fall on to it. Also, it helps you to get rid of the odour which may seep into your house through the drainage sumps.

Does a sump cover help in reducing the radon level?

Since radon enters your home through the sump pipes in the gas form, its flow can be restricted by sealing the sump pits. In fact, some studies have shown that homes with sealed sump pits have lower radon levels that those without sealed sump pits.

There are lots of options available in the market and if you are confused about which product is better and which one to pick, we are here for a little help.
