radon manometer

Every active radon mitigation system includes a manometer, which tells you whether air is flowing through your system. If it isn’t, radon may be concentrated inside your home.

A manometer is attached to the system’s pipes and contains a tube of liquid that indicates if the system is working or not. It’s not necessary to check regularly, but as a homeowner, it’s beneficial to check every so often to ensure radon is being vented out of your home. This simple act can help you maintain a safe living environment.

Reading a manometer may seem complicated at first, but it’s actually quite simple. We’re here to guide you through the process so you can feel confident in your ability to monitor your radon mitigation system.

How to read a radon manometer

A manometer contains two tubes with colored liquid inside. If air is flowing properly through the system, the liquid will sit at two different levels. If the liquid sits at the same level, that means air is not flowing properly through the radon system. 

If air is not flowing properly, we recommend putting an ear to the pipe to see if you can hear the fan. If the fan is off, you may want to check the power outlet it’s plugged into and then check the manometer again. If the fan is on but air is not flowing, call us at 801-871-0715, and we can evaluate if you need any repairs.
