I recently inspected and tested a home for radon and wrote up the defects to the radon mitigation system. Realtor called and complained about the report being wrong. Plumber told her it was fine. Then she called the building inspector and he said it was fine. Client called me back and was wondering who is right.
My response was although there is no licience requirement in Minnesota, good installation practices suggest the following. For safety I recoomend the following.
1.The inspector noted the Radon pipe was installed at 8’-6" in height. The exhaust pipe(s) of soil suction systems must vent above the surface of the roof and 10 feet or more above the ground, and at least 10 feet away from windows, doors, or other openings that could allow the radon to reenter the house, if the exhaust pipe(s) do not vent at least 2 feet above these openings.
2. The exhaust fan must not be located in or below a livable area. For instance, it should be in an unoccupied attic of the house or outside — not in a basement!
3. The inspector noted a missing main label that contains the mitigator’s name and contact information, date of installation, and a recommendation to test the building for radon every two years.
These are the standards from the MDH (Minnesota Department of Health), InterNachi, EPA and every other place I referenced.
Not sure what is unclear?
