Hi,

My radon remediation systm, which features a 3" PVC pipe, had Y
coupling on it and open of the Y's "ears" is open with no pipe
connected to it and no cap. What's the point of that?

So I took a chance and capped it and my radon levels went from 2.8 to
1.8. Did the radon people just screw up or what? Does this mean I can
get a smaller fan now?


Many thanks in advance,

Aaron
