My radon evacuation system has been in place for about 10 years and it operating efficiently. However, the caulk that was used around the outdoor fan has deteriorated. When I cleaned up the area to ready it for a new application of caulk I discovered that some of the air is exhausting out at the fan output connection.
Is this ok? Should I caulk the spot where the air is leaking out which is just below the gasket that attached the exhaust pipe to the fan unit? I have photos and a video.
