- Hey everybody!
John at Fresh Water Systems, and in our
series of answering frequently asked questions,
today we're talking about sump pumps.
What do sump pumps do?
Sump pumps are submersible pumps that
their design and purpose is to move water
Whether it be runoff from a basement moisture,
accumulated water in someones basement,
or in a drain situation where you don't
have a line that moves the water to the drain system,
you can accumulate it in a tank and the sump pump
will push the water to the outside, or to some
other area when the water accumulates to a certain depth.
Do I need a sump pump at my house?
Are they necessary?
Sump pumps are necessary in a household, especially if you
accumulate water in your basement.
For example, an older home with a basement is
built below ground, and sometimes
those basements can be above or below the water table.
And that means that water can seep through the foundation of
the house, and if you don't have a way to move that
water outside, it's gonna accumulate and eventually
flood your basement.
That's where the sump pump comes in.
It sits in a pit like our diagram here and as the water
comes through the walls or through the foundation in the
basement, and accumulates, it runs to this pit and
the sump pump sits in there and when the water gets to
a certain level and the float mechanism raises up,
it turns the pump on, evacuates the water from the pit
so that it can continuously move that water and
How do sump pumps work?
Sump pumps are submersible pumps, and they work by
a float mechanism that tells the pump when to turn on
and when to turn off.
So, we want this pump to move water outside.
A lot of times we'll run the effluent or the discharge line
outside to a pit, or a ditch, or sometimes even into
a french drain kind of a situation.
But, ultimately they sit in this little pit
or they sit submerged in water and as the float
mechanisms raises the water increases it's level in
the tank, it gets to a point where it turns
the pump on.
This one for example uses a floating swi-
a float switch type mechanism to activate the pump.
And it waits 'till it gets way up here to turn the
And then as it drops in level, it turns the pump off when it
gets down about here.
This would be used for a higher volume of water move.
You want to wait until you get a lot more water
before it kicks the pump on.
This one would use- be used in a tank
where you have less water, height anyway, to activate
Where does sump pump water go?
Sump pump water discharge goes where you kinda
need it to go.
For an example, if you're using it in a basement,
you're gonna run the line up and outside
and either run it to a dry-well, run it to a little
creek or a pond that you might have.
You might run it into a french drain type
of a set-up.
You gotta be careful that you don't put it into a french
drain that's gonna drain right back into the foundation of
But basically, you decide where you need the water
to go from the discharge of the sump pump.
Why do sump pumps fail?
Sump pumps fail just like any working mechanism
if they're not used properly, if they're not
applied properly, the pumps turning on and off way
too many times, too frequently.
Cycling is probably the leading cause to any pump failing,
other than that, it's just maintenance.
If you're accum-
if you put this in a tank of water that's accumulating
lots of junk and debris, it's gonna be hard on the
pump, so just maintaining the pumps properly and
make sure you apply them properly so they don't
have an opportunity to prematurely fail.
How long will a sump pump last?
Sump pumps should last somewhere between six and ten years.
If they're applied properly, if they're well maintained,
they should last that full life span.
