Radon Mitigation Install Exterior Remediation System

[Drav1212]

I have a question for you. I had a mitigation system installed and the the pipe runs up along the side of my house. However, they did not put a cap type device on it, I am wondering what happens to the rain and snow that falls down that wide exhaust pipe?

Air is constantly blowing out of the pipe so nothing will fall into it. Any time a rain cap or other type of diversion is installed, it creates problems rather than prevent them. For example, there is a lot of moisture being blown out of the pipe (drawn from below the slab.) When this moisture hits a rain cap, it accumulates and begins to freeze in the winter. Within a few days there will be a big block of ice obstructing the airflow. No cap = No problems.

Why dont they install the fan internally?

EPA rules as of 1996 don't allow this.
