basement sewage venting
I am installing a sewage pump pit for a basement bathroom. The only vent connection I can attach to is 40 feet across the basement and up near the ceiling where the builder installed a capped cut in. Can I run a pitched pipe across that size run and up to the connection? A contractor I inquired with told me to vent it out the side of my house. Its a walk out basement so that vent would be at first floor level? I know its against code but would it work? I prefer to do the run across the basement wall behind an existing wall( it has a chase so I do not have to open any walls) and up to the builders cut in .Suggestions?
