It runs on rare occasions due to the trickle from the A/C, but most times the perimeter foundation loop absorbs that so the pump has run maybe 20 times in it's 34 years. It failed so I bought a new one, connected and tested it. Unfortunately I wiggled the piping a bit too much and it came apart up in the floor joist space, showering me with that old scummy sump water. I'll repipe it. Planning third trip to the store for parts.
