I can’t believe that’s normal. I’ve had sense a couple months and it hasn’t detected my well, but within the first day of having it installed, I saw my usage shoot up about ~2000 watts any (and every) time water was used. It turned out to be a bad bladder in the pressure tank - cost me about $400 but saved me literally thousands in replacing a burned out pump - or at least put it off to a pumps more normal lifespan.
It also could be that you have a leak, if you’re sure it’s the well pump that’s running. the goats knocked the automatic fill float off the tank the other day and I notice my well cycling about every 45 minutes - so that was a good catch as well.
Even if you can’t hear it from the house, it should be easy enough in the well house. I can’t hear mine, but I can feel the vibration in the pump/pipes when it’s running, or watch the pressure gauge.
hope this helps!
