Sewer ejector check valve placement?
We have an ejector in the basement for an in-law apartment. When the check valve kicks in, it can wake us up from a sound sleep. A very loud "thunking". Any ideas?
the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible.
Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2" pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.
