I have a rough in plumbing in my basement. The ejector pit seems to turn on once in a while and I'm not sure why as I have not finished the bathroom in my basement. I noticed it a lot one time when my sump pump stopped working, it would go off every 30 minutes. Now, it goes off once a week or so. I lowered the float in my sump pump thinking that the high water level might be causing a leak into the ejector pit.

Is this a common problem? I'm curious how to solve this and if it is a big deal or not. Could it be that drainage from my heating/AC system might be dripping into the ejector pit?

I don't know! Where are they discharging to? Have you opened up the pit to see what the water looks like and where it might be coming from? Can raising ground water enter the pit? Sounds like it if the sump pump was not working. Ground water could have entered the pit and tripped the float switch. There's one explanation. And your thoughts? Tom

I'm not even sure how to check where the HVAC is discharging to, it appears to go underground in the cement. I'm not sure how rising groundwater can enter the pit unless there is a small leak somewhere that allows the water in. Are others having this same issue?

One thing that I noted is that when my sump pump was not working, during heavy rain, the ejector was going off every 30 minutes. When my sump pump is working normally, it might go off once a week at most.

Should I worry about this at all? My concern is that if my ejector pump fails or in a power outage what would happen to the water in the ejector pit? My sump pump would be fine since I have a battery backup.

Either the sump pump's connected some how to the pit of you have a leak in the pit allowing rainwater to enter.

I wouldn't worry too much. It seems both units are working properly but I would be extremely curious as to how the water gets into the pit in the first place. Let's see where the AC drains to. Pour some food coloring in the AC condensate pan and see if it comes out in the pit. Let me know what you find.Good luck, Tom
