Radon Basement Venting

Maintain a proper slope for condensate drain back.

Radon basement venting. Keep the vent supported every 8 inches vertically and 6 inches horizontally. Radon gas is approximately 7 5 times heavier than air. A 3 pvc pipe is the minimum permitted. Apparently the house was located over a natural radon vent pumping massive amounts of radon into the watras basement.

A new home buyer may ask the builder about these features and if not provided may ask the builder to include them in the new home. The combination of home improvements and the addition of radon removal venting will ensure that the radon within the basement will be removed and stay removed. Check out some basic requirements for running a radon vent pipe. The location of radon exhaust vents can follow the building code requirements for venting combustion appliances which is to keep them 3 feet from operable windows.

Tri level or garden level. Current radon level long term test if possible building type slab on grade. The top of the vent is angled at 45 degrees to the moist air does not cause moisture damage or mildew stains on the siding. It s not a problem everywhere but the bedrock in some regions produces enough radon for it to concentrate on basements enough to raise the risk of lung cancer.

Radon is a radioactive gas and known to be a carcinogen. The second step is to repair the basement to reduce the amount of radon toxins that enter into it. They found radiation levels in the watras home more than 100 000 times the normal background level. Why must radon be vented into the air above my home s roof.

Mixed how many sq ft of each type it is for this reason that it s impossible to size a radon fan before the building is completed and a radon level has been established. In this photo to the left you can see a radon vent pipe that terminates safely about 13 feet above the ground and greater than 10 feet horizontal and 2 feet above the closest window. Radon fits the classic pattern for sneaky building dangers. Steps for installing radon mitigation radon test kits are readily available online and in home centers.

It is however a noble gas with no chemical affinity but is easily influenced by air movements and pressure. As noted earlier radon is drawn into your house when the air pressure in the basement or lowest level is less than the air pressure in the surrounding soil. Install an electrical junction box outlet in the attic for use with a vent fan should after testing for radon a more robust system be needed. Radon can work its way up through the floors and walls of a basement.

In a house with forced air heating and cooling radon gas can easily be distributed throughout the entire dwelling.
