Adding a fan to my Passive Radon System
My house originally tested at 35pCi/L with the electronic meter. I was
absolutely shocked - my house had a passive radon pipe! How could it
be so high?
I sealed the basement slab perimeter and brought it down to 11pCi/L, a
good improvement, but not enough.
I purchased an RP145 fan
from you. I was certain it wouldn't be
enough, as the deck was stacked against me. The builder's passive tube
was a joke - it was 3" PVC (for a 3250sqft house!), it penetrated and
dead-ended in a corner of the basement with no suction pit, and the 3"
pipe run was a long run with many elbows up to the roof. But for $175 for the fan and accessories to install,
what did I have to lose? I installed the fan a week ago.
I am pleased to say that I am now getting consistent readings of
0.7pCi/L! I am absolutely floored. Clearly the fan (combined with the
careful slab sealing) provided enough negative pressure to do the job.
Thank you so much for helping this weekend warrior protect his family
from the dangers of radon.
