how NOT to install a radon system Green Bay WI

We run into this more often than you think. A plumber tells a customer they can install a radon system for them without knowing how to do it. Few years later that same owner calls A-1 to fix the problem. In this case the fan was mounted horizontal which is a big no no. The fan must be vented vertically. This fan over time filled up with water and if you look close you can see the water inside froze and broke through the fan and began to leak in the attic and then into the home. When hiring a radon contractor make sure they are certified to install systems through the National Radon Proficiency Program.
