Radon Vent Pipe Requirements

A 3 pvc pipe is the minimum permitted.

Radon vent pipe requirements. Maintain a proper slope for condensate drain back. See the guide radon fan. Determine vent pipe size and location. See paragraphs 14 5 1 14 7 4 15 7 and 15 8 14 2 radon vent pipe installation requirements 14 2 1 all joints and connections in radon mitigation systems using plastic vent pipes shall be permanently sealed with adhesives as specified by the manufacturer of the pipe material used.

Run a 3 inch or 4 inch solid pvc schedule 40 pipe like the ones commonly used for plumbing vertically from the gravel layer stubbed up when the slab is poured through the house s conditioned space and roof to safely vent radon and other soil gases outside above the house. Check out some basic requirements for running a radon vent pipe. Keep the vent supported every 8 inches vertically and 6 inches horizontally. This is a big problem now you are using the radon vent pipe for a plumbing drain the waste water just drains into the ground below the slab at the radon suction point and depending where it ties in it.

Another important aspect of the radon piping installation is that it must vent 12 above a roof of the building not highest roof or above the peak is required also the pipe must be at least 10 feet from any windows or skylights that can be opened this can be disregarded if the pipe is 2 above the opening. I have seen a few times where people mistook radon vent pipes for plumbing pipes and added a new sink or drain that tied into the radon pipe.
