Can you have a backflow protector on the ducting, so the air is not blown into the other bathroom?
Canadian Contractor FireWe seem to get more questions on bathroom venting than we do on any other topic. Here's another one.
What is it about bathroom ventilation that confuses the heck out of people? Here’s another question on the top from Don, somewhere in B .C. Obviously, not a contractor – no disrespect, Don. OK all you HVAC experts – or just good, old-fashioned renovation contractor who truly know their code – fire away.
“I live in a 35 year old strata in BC. There are two bathrooms, one with a fan and the other with a window. The bathrooms share one wall and both are on outside walls, so the ducting is short. We would like to add a fan to the bathroom with a window only. To put a fan exhaust through the rain screening requires an engineer’s drawings and a rain screening qualified contractor. Can the duct from the new fan join the duct from the existing fan to exhaust through the same outside opening? Can you have a backflow protector on the ducting, so the air is not just blown into the other bathroom?
Thanks, I appreciate your expertise.”

Why doesn’t your cash work poll have the option of “none” without all of the commentary. I simply tell people they can pay me cash if they like but that I will still be charging taxes. I have never had a problem. In all fairness, I remain busy without advertising as a referral based home improvement contractor.
Vent the new fan separately through the roof
