Sump pump running often for first time ever


Yes - my pump runs for 12 minutes at a time if the pit fills up
I sometimes click it on myself before it reaches the set point

Sump pump running often for first time ever


Pkovo and Scuba Dave (or anyone else!)--

I did the math and figured out given the dimensions of my pit and that it only takes the water level down 3 inches each time the pump goes on, it is only expelling 2.2 gallons at a time. So that means it is only expelling 33 gallons an hour even going on every 4 minutes.

Is 33 gallons an hour a lot? Or is the reason my pump goes on so often is because of how little it is expelling at a time?

I'm sure that contributes to the frequency. If you had a high volume drain tile system like Scuba does, it would take much longer to fill up, then much longer to pump out. Plus a drain tile system collects the water more efficiently.

Is your pump still running? I heard mine run twice over the weekend, but I think it now finally stopped. The pit still has water, but at a level and inch or two before the point where it will turn on the pump.

I timed mine, it pumps for about 15 seconds each time it cycles.

Three inches and 2.2 gallons at a shot is not ideal for a sump pump but you may have to live with that for the time being.

If the pit itself is wider so each inch of lowering means more gallons, lowering the water level only 3 inches is not that bad.

You might want to consider digging the pit deeper so the bottom is at least a foot below where the perimeter drain pipes enter.

My pump is still running but finally slowing down--to once every 38 minutes. And when it runs, it only runs for 5-6 seconds.

I decided to measure the amount released by putting a bucket where the pipe ends outside and it actually was more like 4 gallons. I know I measured the pit correctly so I assume the holes in the pit below the water level also drain out water.

I don't have a perimeter drain that dumps into the pit (my house is old--early 1940s). Instead, my pit is clay with small holes every couple of inches on each side that drain water into the pit.

I think if my pump were set to go off at a higher level, it probably would be going off hardly at all or very seldom as when I turned off the pump a couple of weeks ago after six hours the water level still hadn't risen above the top and was barely taking in more water (only 1/4" in the last two hours).

I now believe it is a high water table issue as after the pump goes more often AFTER the rain stops and it has never gone off before. The news announced that the last 12 months have been the wettest ever for Philadelphia.

I really don't want to dig up my basement floor to make a bigger pit, although I know the size isn't ideal. I'm going to monitor the pump and see what happens as the water table goes back down. If the pump stops going off and still doesn't go off during heavy rain storms (as in the past), I think we'll stick with our small pit. But I still think we might get a backup pump, especially as our flow rate is slow enough that a backup pump would pump out enough water to keep water from coming into our basement.

Try setting the pump turn on level higher, leaving the turn off level at the same low level it was at. But monitor the pump and also monitor the basement for wetness all around especially in the far corner.

It will take a couple of days for the water table under the house to settle down after each adjustment you make to the pump. In addition, the weather will exert other changes on the water table.

I would say your pit/pump worked fine. Maybe it worked a little more than it needed to since the turn on point is deep, and it's a short cycle, but it kept your basement dry which is the most important thing. The water level in my pit is slowly falling. Barring anymore significant rain, I suspect it will be dry in a week or so. Hopefully it won't run like it did in March for a long time!
