Radon vent pipe ends below the roofline
The radon mitigation system's vent pipe terminates below the roofline, which does not meet best practices or current EPA guidelines. Proper radon system design requires that the exhaust point be above the highest eave of the home to prevent radon gas from re-entering through windows, soffits, or attic vents.
Why it matters
Improper vent placement can allow hazardous radon gas to accumulate near the living space or be drawn back into the home, reducing the system’s effectiveness and potentially increasing health risks.
