It's not just the occasional window, it's the bathroom fan, the kitchen fan & the stinking laundry drier..
Not more than 18 feet above the
Radon Gusher, is my leaky, up-drafting attic pull-down stairs!!
Seems like my work is cut-out for me..
I've been periodically measuring various points in the basement for years,
this is the first time for this brand new sump hole..
Stupidly, I skipped testing that one this past summer, due to the big pile of stuff stored in front of that area.
The readings have always been under 3, so needless to say, I was totally shocked to find the stinkin Gusher..
