I've just installed my 3rd sump pump in 14 years. Granted, that's probably better than some, but since high water is typically not a problem in my neighborhood, I think I should get more life out of these pumps.
This pump failed 3 days ago. I didn't have time to replace it immediately, so I just kept an eye on the water level until I had a chance to buy a replacement. Over the 2 days it was out, I made what I consider to be a startling observation. The water level rose during the first day, as expected (the pump runs frequently when it's working, so rising water didn't surprise me). However, it appears to have topped out at about 12" from the top. This caused me to wonder if I would be better off raising the height at which the pump starts so that it starts only when it exceeds this 'natural' level. I'm speculating that this could result in a considerable savings in both electricity and wear and tear on the pump.
Am I off the wall on this? Is this common practice? How would one go about this with a submersible pump? Could I put it up on blocks? Or is there a way to adjust the float? (memory doesn't provide me with any clues because I didn't look at it with that in mind when I installed it) Would there be issues with stagnant water in the pit? Any other considerations?
Thanks, Mike
