Hi All,
I have my "work" desk in the basement, right where the monometer is for the radon mitigation system. It seemed to have a low reading, and I thought the fan (in the attic, near our bedroom, can hear it in summer/with windows open) was a bit loud.
So, I took a picture of the data plate for the installed fan (a Fantech model HP190) and bought what I believe is the replacement model (a Fantech RN2). As far as I can tell, they have very similar airflow curves, though I can only find data for a newer HP190 (mine was built in 1997, and says it uses 90 watts, whereas the data for the newer HP190 uses less wattage).
I replaced the old fan with the new and turned on the new fan.
Basically, the before and after monometer readings are the same. I show one here.
This seems to be a relatively simple system. It's a 3 inch pipe that runs from the basement, to the attic, through the fan, and out the roof. That's it. Basically, a straight shot.
Are there any debugging steps I can take to see what the issue is? Thank you.
Also, if this does not belong in plumbing, please move it to wherever is more appropriate.
