manometers to test radon system

Radon is removed from a house by installing a radon mitigation system. Once the mitigation system is installed, Utah Radon Services will do a post-mitigation test. This is to ensure that the levels in your home are reduced below 2.7 pCi/L, the action level recommended by the WHO. Once the system is installed you may ask yourself, "how do I know if my radon system is working?"

The Environmental Protection Agency (EPA) protocols require that every active radon mitigation system have a "u-tube manometer" to warn the homeowner if there is a system failure. This device is installed on the vent pipe which is installed into the suction pit underneath the concrete slab of the home.

What Are The Signs My Radon System Isn't Working?

You can use the u-tube manometer to determine if your system is working. Look at the liquid in the tube. If it is equal on both sides, it is an indication that there is no pressure in the pipe. This means no suction from the fan (far left image) and the radon mitigation system is not working.

If your radon mitigation system is not working, you need to have the system checked out by a radon mitigation specialist. They will be able to determine why your system is not working. In most cases, if a mitigation system is not working, the fan will need to be replaced. Pricing for the fans will vary depending on the model.

If the liquid in the pipe is uneven (as in the image on the right side) your system is working properly.

Call 801-871-0715 to speak with the radon mitigation specialists at Utah Radon Services. We can evaluate your system and determine what needs to be done to get it working properly again.

Utah Radon Services has a lifetime guarantee on their systems and a 5-year manufacturer's warranty on fans. We are also able to inspect systems installed by other radon companies. We can determine any issues and do the work to get it functioning properly.
