| Could someone please tell or show us how to install air vents in our house's plumbing? Evidently, our house was built in 1976 without any venting. Where do we put them if we were to do it ourselves? Are Automatic Air Valves OK to use? What about just one AAV on the upstairs bathroom sink? Thank you! |
