One thing I've noticed living on the side of a hill, is long pipes running down hill,
from the sump pump, can cause a siphon effect.
If the water is coming in pretty fast, the siphoning action might keep up
with the in-flow, or run just behind it.
I got my neighbor across the street to add about 60 feet of hose to his pipe,
which was dumping on the grass, right beside his house.
(And going right back in to his basement).
I could see the hose jump when the pump came on, but water would still
be flowing for a long time after the pump shut down.
Depending on the speed water was coming into his basement,
sometimes the siphoning would go on for 20 minutes before the pump re-started.
When there was less flooding, the siphoning would run for a few minutes
and stop, without the pump coming back on.. For a while anyways..
