Installing a radon mitigation system in a home usually means placing a pump in the basement or crawl space, running completely sealed pipes from the pump to the uppermost part of the house and installing a radon fan somewhere in the non-living portion of the house, according to indoor air health expert Val Riedman. Radon seeps into some homes from the ground and can cause lung cancer.Continue Reading
When radon issues are suspected, the first thing to do is to test the house for radon levels. After that, check for any cracks or holes in the lowest level of the home, either in the crawl space or basement. Radon can seep into a home's living space through these holes and cracks.
Pipes for residential homes should be 3 to 4 inches in diameter from basement to roof. In homes, the usual material is PVC piping. The radon fan, which is attached and sealed to the pipe system, is located either in the garage or in the attic to prevent possible leaks from contaminating living spaces. Pipes terminate no less than 12 inches above the plane of the roof and cannot be within 10 feet of windows.
Another key planning step is to determine how PVC pipes should run through a home. Holes must be drilled in floors and ceilings to accommodate a new pipe going from the basement to the roof. For do-it-yourself projects, the book "Radon Reduction Techniques for Existing Detached Houses" is the authority on the subject.Learn more about Heating & Cooling
