![]() ![]() My design is that if the floor drain overflows and any backups would/should overflow into my sump pit where it would be directed outside. In my case, the lowest point would be a backup into where I plan to install a floor drain. Being as the ejector pit is located in the basement, if it backs up, it would backup into the basement. One last thought.if the main sewer line backed up and was not able to flow into the sewage ejector pit, then the flow of backup is likely going to be a tub or toilet above the main drain and a likely overflow into finished living quarters. I don't doubt there are some great plumbers out there that know their trade inside and out, but I don't seem to find them.until I look here for advice!!! I thought he isn't giving me any advice I with my limited knowledge couldn't figure out, in fact, I read his advice was wrong, so why should I pay him. I had a plumber tell me that it was ok to tie it into a vent, which is why I plumbed the rest myself. I tried finding reason's as well as to why I couldn't tie my ejector vent into one of the "normal" house vents and that is what I kept coming back to. On the discharge section of pipe, there is a check valve to stop any sewage from the main line from entering the ejector pit, on the vent there isn't. I'm of course not a plumber, but the only problem I really see with this setup is that there is nothing to prevent a sewage backup from coming back up this vent pipe and into your ejector pump. The vent is all I have to run to get my system up and going and I was planning on running it up 2 floors and out the roof, which is going to be somewhat tougher than I originally thought. I'd love to know the answer to this as well. I would appreciate it if someone can explain the studor diagram to me on how this thing works and comment on why studor believes an AAV can work with an ejector pump, while the general consensus is against this practice. I assume this is how the box is equalizing the pressure. I don't hear the mechnical vent, but after a big laundry load, I get some gurgling and the valve makes a little "hiss" for about 3 seconds after the pump shuts off. On the shorter cycles, the waste pipe shutters after the pump shuts off, but I think this is the water flowing back to my check valve, which is mounted about 3ft up the vertical pipe.īTW: I am using a standard mechanical vent temporarily until I can find the proper studor valve. I did at least a dozen full sink-loads of water, two laundry cycles, and numerous on-off cycles of water going down the drain. I don't know how it works, or how long it's going to work, but the pump functions. So, I pulled the old sink and pump out, installed a new sink/faucet and rigged up the new pump as per the design diagram. In any case, I figured I can do no worse than what the so-called "plumber" would have given me, and certainly better than what I originally had. They basically have the vent coming out of the box, and then a loop back from the waste discharge to the vent again. Take a look at this diagram on page 14 of the Studor design manual: The spec sheets for their valves state: THE VALVE MAY BE INSTALLED ON SEWER EJECTORS, IF INSTALLED ACCORDING TO ENGINEER DESIGN. So I have this pump and an AAV, and according to STUDOR, it is indeed possible to use an ejector pump with an AAV. Hence, why I am here and asking for your help. The system is broken and this corrupt practice serves nothing more than to enrich unscrupulous master plumbers while depriving the public of having a licenced professional do the job. This is a very frustrating situation, and I've already twice had to get the board of master plumbers involved to penalize master plumbers for allowing idiots to screw up my plumbing jobs. What you get are the retards that work under the master plumbers licence, hence the bad advice. I searched the forum here and the internet, and the definitive consensus is that a pump in the box won't work with an AAV.Īs an aside, I live in NJ, and in this state, it is impossible to get a master plumber to come to your house. ![]() First thing I see in the pump manual is that the pump can't be used with an AAV. ![]() Going to the roof would be a major expense.Īnyway, the plumber cancelled on me, so I went and bought the supplies myself. ![]() So, I hired a plumber to come out to fix the problem and he suggested a zoeller pump in the box with a sure-vent. It was disgusting, with a constant 1-2" of standing, dirty water in the sink at any given time. The original owner rigged up a rube-goldberg contraption, with a pump mounted to the bottom of a sink, and a float switch mounted IN THE SINK. I just bought a home with a basement utility sink below the sewer line. ![]()
