Hi, I have a bathroom in the basement that was missing the drain setup. Not really plumbing savvy so bear with me. I been back and forth to home depot numerous times with no success. It seems that I'm missing a piece that I dont know of or modified the pipe too short. Please help.
it is really easy to add in an AAV, and will bring the installation up to code in most places, and will stop that annoying sewer smell that an s trap tends to bring.
No where in the USA. You touch it, it has to be replaced up to code. Now, the HO can do whatever they want as long as it is not inspected. The S-trap will present possible health hazards for the family though.
