Getting to Know Your Manometer
Getting to Know Your Manometer

If you’ve had an active radon mitigation system installed (one with a fan that helps expel radon gas), then this photo of a manometer should look familiar.

This device measures the pressure in the pipe to easily show if a fan is working. Having the levels UNEVEN is exactly what you want to see!

If your manometer shows EVEN levels in the U-tube, make sure you call a radon mitigation specialist to check your fan out.
