The pipe goes beneath the basement slab and into the soil. This helps ensure the radon gas is pulled from the soil before it reaches the air in the basement.
From the basement, the pipe pokes through the wall and connects to a fan, which pulls the air from beneath the basement slab into the pipe. The strength of the fan depends on the subfloor air communication beneath the slab. A manometer installed on the pipe in the basement helps the homeowner identify whether or not the fan is operating correctly.
The radon pipe is extended up above the roof line of the house, ensuring the radon gas is released into the air at a safe distance to the house.
The homeowner tested his home in 2015 and the level was 4.0 pCi/L. As a standard, the Environmental Protection Agency (EPA) has defined 4.0 pCi/L as the "action level" for any indoor environment. He then tested his home a year later and the level was 9.8 in the basement and 4.7 upstairs in the home. Erickson Foundation Supportworks installed a radon mitigation system to improve the air quality in the house.
