Hi,

I noticed that the sump pump in my house seems to be running every 1.5 hrs
even when there is no rain. When I checked the sump, I found that there
seemed to be some flow into the sump from one of the two pipes draining
into it. How can I find out where the water is getting drained from?

Any help is appreciated.

Couple of things come to mind from your post. Type of soil, location
of home in reference to other homes, proper water drainage away from
foundation, high water table, short-cycling the disharge water back to
foundation wall, check valve on discharge pipe.
