Default Sump basin leaking

Whatever the level it stabilizes at is the level of the ground water under
your house. If you want that level lowered, either try to prevent it from
entering by way of curtain and foundation drains, or set your pump to
whatever level you'd like it at

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:
Make 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.

It is discharging plenty far away from the house and the pump does
have a check valve installed (and correctly).

Perhaps you need exterior grading away from foundation or somesuch.

We are looking to improve the grading to keep water going away from
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)
