As a plumber this is part of the job.


When I moved to NJ in high school in the 1980s, there needed to be a vent for radon gas. Didn't help with the NJ jokes, but it's serious stuff.


In the 80s there was an article in Readers Digest on Radon and listed a NJ house on "Whispering Hills Dr" in the story that had an absurd value of like 200+ picocurie. That was the house across the street from us. We had 14.7. Took a lot to get theirs down, ours was pretty easy. French drain was the main problem.
