![]() The discharge pipe of the sewer ejector or grinder pump should be connected to the main waste line through a wye fitting and it should come in from the top. Only the fixtures below the main sewer line should be going to the ejector pump. If you are on an upper level of the home and use a toilet, the sewer ejector should not be turning on. Plumbing fixtures that can drain to the main sewer line by gravity alone should not be discharged into the sewer ejector pump. Code 3 - Only Fixtures That Need Pumps Should Be Connected Air admittance valves would release sewer gas into the home and is forbidden. Venting should be at least 1-1/4 inch in diameter and air admittance valves are not allowed. There must be venting installed when there is a sewer ejector pump in a basement.

This cover should also be removable with some screws or bolts. Regular sump pumps don't need to have an air tight lid, but for obvious reasons, it is unhealthy to have sewer gases seep into the house.Īs a home inspector, I usually just try to visually make sure the lid is tight, and I don't usually remove sewage ejector pump lids. I’ve never seen so much pressure.Sewage ejector pumps must have a sealed and air tight cover to prevent sewer gases from flowing into the home. We ended up having to find the curb stop and shut it off there. So much so that when we tried to install a new pump the pressure would immediately push the gooseneck discharge out of the pipe and would spray sewage water 8 feet in the air. The discharge pipe was highly pressurized. The pumps we put in test at 4 amps and then when they failed they tested at 20 amps. We have been to this house multiple times this week. I responded to a grinder alarm yesterday. The bracket was installed properly, I used multiple brackets, and the windings tested ok. There were 1 or 2 that would just start clicking when I tried to test them in the shop. I’ve attempted replacing the control bracket on a few of these extreme series pumps. ![]() So I have 2 questions for anyone familiar with these. I’ve been at it for 2 years now and am still learning. My job consists of replacing failed pumps and trying to refurbish them. Mostly the 2000 series and extreme series. I work for a contractor and we service a lot of towns and cities that use these stupid pumps.
