Can you connect a bubble up raydon system to the air system?
An air system was already installed for radon when we purchased our house. We had a water system installed after (bubble up) and the installer said he could run the water system vent into the air vent. We just had the bubble up serviced by another company and was told what the first guy did was illegal and it will cost $4 to $500 to fix it. Just trying to find out if it is legal to do it.

I'm not familiar with this system, but the manual does not say you cannot share a vent line. That said, the existing line may not be properly sized or pitched for the Bubble Up unit. It's also possible that the existing radon pipes might provide a way for the radon exhaust to enter your home.
If it were me, I would check with my local code enforcement office and probably also seek out a fresh opinion from a well-regarded installer.
Thank you so much for the quick response. I will call my town hall. Have a great night!
