I had a rough in done in my basement that allows for my washing machine , a small sink, toilet and shower. They installed a vent pipe coming up through the floor connected to the rough in bellow the floor that was meant to go to the main stack but due to location of the stack it would be to costly and trouble through a brick wall, etc. Will the oatey sure vent 20 service my situation. I was also told the vent can be used as a wet vent for my furnace.
