Sump pump issues need help


My sump pump under normal circumstances usually pumps about once a minute. I am noticed the last couple of days with no rain or any other reason to run more. After it does its normal discharge that within maybe 10 seconds it pumping again and it is a small amount. Any help would be appreciated as I do not want the pump to burn out as it is an expensive Zoeller. Thanks for the help..

sounds like your check valve is not working. It is allowing the water in the vertical pipe the pump pumps through to run back into the sump. It is apparently enough to cause the pump to kick on.

have you looked in the sump (the pit the pump sets in)? If I am correct, what you would see is when the pump turns on the first time is; the water would reach some level, pump turn on, level go down, pump shuts off. Then, you would see water coming back into the sump through the pump.

If you could set the float to not turn on until the water gets a bit higher, you might be able to get above the situation where the backflowing water is what is causing the pump to kick on.

If you are a true DIY'er, you might consider changing the check valve yourself.

You might also find that something got pumped up and is caught at the check valve and holding it open a bit (allowing the water to return but not quite as fast as a fully failed check valve).
