Hello. Hoping someone may have some advice.
We built a new home about 2 years ago. Reputable builder and generally happy but we have an issue with a single bathroom exhaust. There are 5 bathrooms in the house with 6 exhaust fans (powder room/shower separate) and we have a problem with a single fan.
In that room you can clearly smell the outdoor air and feel cold air blowing down from that exhaust. All the others are fine. In the winter, the temp is consistently 6 to 10 degrees cooler and you can feel the draft. If we have a fire outside (fire pit/bonfire) you can smell the smoke coming inside.
Builder tells me that dampers are not customary on these things.
He replaced the fan with a new unit and a different type of outside part. No change.
As a short test, we covered the exhaust fan with plastic wrap to confirm this was the source of the air. It seemed to be confirmed.
One friend of mine is wondering if the vent hose/pipe is too short. This bathroom is against the side wall to the house and the vent goes directly outside just above that wall. He opines we may need to extend the pipe. Would this really help?
The area above this particular exhaust fan is an unfinished area with opening to the outside. That area is insulated but when you go out there you can smell the outdoors as well but I would assume that's normal.
Any advice on what to try here? Thank you.
