Are these changes needed?
Thanks for everyone’s input on this thread! I appreciate all of your experience! Being a newbie to radon mitigation, only 16 years in industry, however schooled by Arthur Scott and jack Bartholomew. I really don’t understand why you are afraid of validation, through simple math?? I literally know success and fan size in less than 10 minutes and validation of fan selection in less than 1 minute- yes I’m a indoor fan guy, with rim discharge, with only 4000 systems installed, but I guarantee less than 100 Bqm3 not our guidelines but WHO.
Never had a failure!
As Colin said, a little sealing goes a long way! Job today, RN 1 was way too strong! Got 46 pascals at furthest point, however didn’t change house pressure.0.0001 pascal- all things you need to know! So stop pushing back! Educate yourself! Do I write a book about every job- no, my test results are simply left on utube label, so anyone can duplicate my design!
You need to know house negative pressure potential, fan required to draw 2.2 times that, to allow for variables of temperatures, wind etc, then a simple communication test- and fan selected!
As Jack would say- know your PFE! Got the shirt!
RIP my brother!
