Hello there, fellows. I'm posting here because I hope you guys can help me figure out what I have. (Pardon my newbie-ness, but this is my first house and the first plumbing I've ever looked at in my life.) I have a basement bathroom with a sump pit in it. I know I have an ejector pump because when we run the shower, I can hear it kicking on (loudly). The question I have is... why does it also kick on during rainstorms? I know the sewage and the groundwater-runoff systems are supposed to be separate... so what's going on here? Do you think it's likely that I have a sump pump and an ejector pump, both contained in the same sump pit? Is such a configuration possible / normal?
Thanks for your insight!
Edit: P.S. - We're on a well with drainage field, not public sewer, in case that makes a difference.
