Sewage pump mystery
After sufficient water usage the sewage pump in my basement will turn on QUIETLY but NO waste water is being moved. It will run like this for hours maybe even days without moving any water. To solve this I unplug the pump for a few seconds. When I re-plug it in you can hear the water being pupmped out. It will then empty the well in a few seconds. Why is it necessary to unplug and plug the pump to get it to work. It sounds like it is running but you can hear that no water is moving until this is done. Could there be something stuck in the "well" that floats up when I unplug the pump, thereby freeing the impeller to turn????? But if the impeller was jamed wouldn't the motor have burned out by now? It will be difficult to open the cover to look in the well so I am hoping for an easy fix. Thanks in advance for the help.
I think you are losing the "prime" in the pump each time it kicks off..not a pump-expert but I do know there is a specific way of installing the outlet pipe with a weep-hole near the bottom (drilled by the installer) to prevent this problem. erik
Thanks for the info. Anyone know more about "weep holes" like: Where would I find the one that is apparently plugged in my system?? In the well??? Tnx again
If you have the manual for the pump it will show how and where the hole should be drilled on the discharge side of the pump.If you dont have the paperwork look for the brand/model and request from the manufacturer via internet. erik
You can drill a 1/4" weep hole yourself. Simply drill it on the discharge line like Eric said. The easiest way is to disconnect the check valve, and drill it between the male adapter and the check valve. The reason for the weep hole is to drain out the water that is between the discharge side of the pump and the check valve. Naturally if your check vave is not in the sump, this is not feasable. This should hold the prime on the pump. Also if your pump is for effluent discharge you need to periodically clean out the screen.
Turns out to have been the one way check valve. The tether for the flap was gone. When the pump kicked in it would push the disc/flap against the top of the valve housing. If it got a good seal it prevented the water from leaving so the pump stayed on. This pressure build up caused the rubber sleeves that connect the one way valve to the pipe to burst (yeech!) So all is good now with a new check valve.. Thanks again to everyone for taking the time to help me here.
