Agree. It's not all that unusual for one house to have a sump pump
that runs more than others in the neighborhood. The ground contours
and water level are not perfectly uniform. For example, in some
places, a natural spring will be bubbling out of the ground, yet 25 ft
away, there is no evidence of water at the surface. You basement
could also be 6" deeper, or have another entire block course, which
could make a significant difference
Forget the idea that somehow plugging any holes in the sump pit is
going to stop the pump from running. Water is going to seek it's
natural level. It's unclear where the 10.5" is being measured from.
But if you want the pump to run less, raise the float level a bit.
But be careful and keep an eye on it, as if you go higher, you
increase the risk of water showing up somewhere in the basement. It
will try to make it's way over to the sump pump, but the higher the
sump level, the lower the delta to make it to the sump low spot,
instead of surfacing somewhere else.

Allrighty gang - here's what I've deduced/tried out thus far:
The foundation does appear to have a drain tile present with two
corrugated plastic pipes feeding into the sump basin - it's my
understanding that the only water that I should expect to see feeding
into the basin should be from these drain tiles as the sump basin is
the low spot in the drain tile setup and not from underneath the sump
basin (where I am currently seeing a large waterflow/influx). The
only other potential is that the two corrugated infeed pipes are
coming only from the basement window wells as an overflow versus being
present for a drain tile as I was told during the buying process.
The biggest "question" I have is that my neighbors are not seeing
anywhere near the pumping that I am (up to 5+ times / hour), where
they will have almost nothing.
The water table seems to equalize at around 10.5" in depth (still
below my "drain tile" hoses), but high enough to fill the basin. If I
pump it out, it simply gushes back in with great force from the holes
in the ground.
Some other thoughts:
It is discharging plenty far away from the house and the pump doesMake sure the discharge is going 10+ ft from the house.
And there should be a check valve in the line to prevent water
left in the line from siphoning back when the pump shuts off.
have a check valve installed (and correctly).
We are looking to improve the grading to keep water going away fromPerhaps you need exterior grading away from foundation or somesuch.
the house, but again, the biggest question in our mind is why does
ours go off and literally flood parts of our yard as its pulling up
groundwater while neighbors units are not doing anything. I would
think the overall water table would be relatively similar from house
to house (~15 - 20' away)- Hide quoted text -
