I have a passive radon system already setup in my house (just the pipe from the gravel to the roof) and want to get an active system on it. Trying to save a little money, so I'm planning to just buy the fan myself and just find someone to install it. Was looking at the following to get, but figured I'd see if anyone had better suggestions before I pulled the trigger. My basement is about 1200 sq/ft with ~600 of that finished, if that matters. I'm assuming if my pipe says it's a 3" pipe, I should get the 3x4 couplings for the fan? Should I buy my own fan at all, or let whoever I get to install it bring their own system (not sure if an installer is generally going to mark it up vs. if I bought it myself).
Also, why the hell can I not get amazon links to work?
