Recently after a ejection pump change out a few months ago, the check valve doesn't want to release due to apparent air pressure coming from the main waste pipe. The pit is 4 ft from the main cleanout which is the last foot before it disappears into the street. With the cap of the cleanout off, there's a nice blast of (fresh?) air coming out. Suspecting a old valve, I had changed it out and mounted it horizonally according to the recommendations of the manufacturer in addition to an air bleeder hole slightly above the base of the connection and rodding the cleanout to approximatly fifty feet. The problem hadn't gotten too much better resulting in the property owner calling for the street dept to check things out. He had taken it upon himself to remove the cover to 'looksee' and got a crappy perspective for it. Well the city said there was grease in there. Considering all the used condoms that came out with the aforementioned perspective, unless the manager of the carryout restaurant has something going on in her apartment above the store, there's dysfunction's with the city. At this point the owner has the check valve totally off. I've insisted that he reinstall it as soon as possible for the obvious reasons that city code requires it.
The Questions is this: There's a 45 degree angle from the horizontal to the waste stack about 6 inches long. Would extending that length and shortening that of the horizontal 2 inch pipe containing the check valve increase the pressure enough to overcome the air holding the new check valve closed? Or might I suggest getting the city engineer in there and ask why in the wide world of sports after 30 years is this happening? Glad to hear any and all ideas.
