we have a washer and when it is used it smells like sewer gas when in use.
the drain pipe has a cheater valve on the top of the drain pipe.
could the cheater valve be removed and have a 90 degree elbow put on it and then vented thru the outside wall or will I have to look at having it vented out side thru the roof like a normal sewer vent?
The washer and dryer are located on the main level of a 2 storey house. I just want to get rid of the smell when it is being used
I am in Ontario Canada, if the plumbing code matters
