We get approximately a bucket of new water every hour in the sump pit. When
water level reaches half of the sump pit it does not rise any higher. As a
result the sump pump runs once or two in an hour. None of my neighbors have
Is this a problem?
Well, I'd say that you have issues. Water full time means that you are
either in the water table or on top of a spring or similar flow under
your basement. If the pump works, that's good... but if the power goes
off in a storm, it sounds like you're going to be very, very wet. You
need alternative drainage or a battery or generator backup.
You might want to call in a pro who can consider a *passive* drain
around the foundation to remove the water without a pump. Read some
more at this page to enhance your understanding of drainage
Is this a new house/development ?
House was built in 1995. What also strange is that water reaches certain
level and then stops or at least goes up very slowly.
I am looking for a batery backup sump pump. Before recent blackout I was
thinking about backup pump that is tap water driven, but it turns out that
you may not have both power and water...
Maybe there is some natural or other drainage that works marginally at
If you have city tap water, it is very unlikely in most areas that it
will stop. They pump the water into large tanks holding millions of
gallons. The water is fed to you by gravity. Call your water
department to be sure. It's possible that there's a pump between you
and your water.
Those tap powered devices use as much water as they dump. So, you use
a gallon of water for every gallon you pump.
If I were you, I'd call some drainage people (people who like to dig
holes with excavators) from the local area. You want someone who has
an engineering degree - not just a digger. Try people who do septic
systems and also excavation. Get them to take a look and see what
they say. They will know a lot more about local soil and water
conditions than anyone here and can advise you on site. Of course,
you may find that you can buy a quality generator with automatic
startup and transfer for less than the price of a proper foundation
drain, so it might not be the way to go. No one can say until you
It really depends on the depth and what's underground. My pump
used to run very often, along with 2 neighbor's pumps. The
town, where I live, installed an anti-backflow system in my
front yard, to prevent backup from the city sewer system. Now,
my sump pump hardly ever runs. We have had huge rainfalls in
the last month and the neighbors were pumping water regularly.
My sump was totally dry for most of the time and just recently,
filled with about 3" of water ... not enough to trigger the
pump. What happened here? I really don't know, however, either
the anti-backflow unit is blocking the underground water flow,
or it is pumping the underground water into the sewer system
(this is illegal, but it is the town's doing). This unit does
have an ejector to pump house sewage into the backing up sewer
system when the backflow valve is actuated. There is a control
box that shows when the pump is running, however, I don't sit in
the basement watching it. I have only seen the pump light on
once for a few seconds and that was a year or two ago. Someday
I'll hook up an elapse time clock to the control box to see just
how much the pump runs during non-backup times (maybe once every
This was happening to me. The sump pump was installed incorrectly. The
plumber came back and drilled a hole somewhere. Evidently what was
happening is that it was sucking like a straw and couldn't get all the water
out because, like a straw closed at one end, the pipe held the water in.
Then when the pump turned of the check valve released and all the water
flowed back in, so the pump had to run again.
Had this condition not been corrected the pump would have burned out. I am
sorry if I didn't describe it better.
