No matter where in Wisconsin you call home – Appleton, Kaukauna, Oshkosh, Fond du Lac or surrounding areas – the examples below show what can happen when your Radon mitigation contractor lacks experience. The installer of this system, a local competitor, is certified to install Radon mitigation systems, but has not had the benefit of mentorship from another installer with experience. The homeowner saved approximately $50 by using this company. But to bring this installation up to State of Wisconsin electrical code and recognized Radon venting standards, it will now cost him another $150 or so. Let’s look more closely at what’s wrong with this installation.
Closer Look: An Improperly Installed Radon System
From a distance, the photo on the left may seem to portray an OK Radon system installation. But, if you look closely, the vent pipe does not meet the minimum requirement of being two-feet above a window that is within 10-feet of the vent. The danger here is that Radon gas can easily travel from the end of the vent pipe, right into the window.
This photo to the left shows an electrical hook-up done improperly. You cannot have an outside fan on a electrical cord. For one thing, there are no cords rated for sun resistance, so this is a fire hazard. And for another, you cannot run an electrical cord through a wall to plug it in, in this case in the basement.
Finally, this photo on the left clearly shows that the exhaust fan was installed at an angle. These fans need to be installed level from front-to-back and side-to-side to get the proper life expectancy out of them. The most frequent cause of premature fan failure is a fan installation that is not level. The bearing in the fan will get off balance, cause a lot of noise and then die.
Also, notice that there is no cosmetic flange installed over the pipe going through the wall to cover up the caulk and protect the home from the elements.
