I'm lost. We purchased a ranch with a basement and apparently we are in a
low area so our sump pump runs a lot.

We have your basic sunken sump crock and we have 2 submersible pumps in it.
The primary pump runs underground to a sewer at the street. The backup just
drains out to the yard and only is supposed to run if the primary would
fail.

They both use float switches and the primary sump pump float switch died, so
I installed a new one.

My problem is I don't know where to set the kick in level, to turn on the
pump. Meaning, how high should the water level get in the sump crock?

There is a 4" drain pipe from the drain tiles that empties into the sump
crock and it is about 10 inches below the top of the sump crock. When
should the primary kick in?

If I set it low, water constantly runs in from the inlet. If I set it high,
so it doesn't kick in until the water is above the inlet pipe, than for the
most part the water seems to equalize itself in the crock and it maybe runs
every 5-10 minutes in spring.

Should the pump kick in below the inlet pipe level, or just let it equalize
itself until there is enough water pressure coming in to raise the float?
