The previous owners of our house replaced a downstairs closet with a small bathroom. This bathroom is at the back end of the house, where the main vent stack is at the front of the house.
When you flush the toilet, it sucks the trap in the sink dry, couple of hours needless to say it smells of sewage. So I’m assuming that since the vent stack is at the front of the house were the main bathroom is, the downstairs bathroom isn’t vented right.
HOWEVER, the original kitchen sink along with an original sewer line is right on the other side of the bathroom. So the toilet and bathroom sink are tapped into an original sewer line where the sink is tapped in. Let me add, the kitchen sink is also sucking water out of the bathroom sink.
I’m thinking this is a new issue since the house and the kitchen sewer line are original with the 90 year old house. Regardless I have a venting issue. My question it would be really difficult and costly to run a new vent outside, is there another solution? Thanks in advance.
