Do Radon Mitigation Systems Make Noise

There are two noises that are generated by the radon system: air flow and vibration. … Excessive noise and back pressure is created when too much air is moved through the pipe. According to the best standard, a 3” pipe should move no more than 34 CFM before the system is too noisy and loses efficiency.

What does a radon mitigation system sound like?

If this arrangement is not working properly, water will be left in the pipes. This will result in a gurgling or bubbling sound, like that made by a straw when the glass is just empty. If the gurgling noise your radon system makes is coming from somewhere near its fan, the culprit is the condensate bypass.

How do I make my radon system quieter?

Open face fiberglass insulation can be placed on top of the membrane or in the joist cavities above the suction location to dampen the noise. The smaller the pipe size drawing air from under the membrane the quieter the air flow noise.
