Sooner or later the float switch on your sump pump is going to fail. There
is no way to predict when it will happen, and there isn't any way to tell when
it is starting to fail. The only thing you will know for certain is that it
has failed, and that is because you will have water all over your basement,
and a big plumber’s bill to look forward to, ranging anywhere from $200 to
$500! Plus the expensive repairs from water damage!
What is a float switch?
The float switch is what turns your sump pump on and off in
response to the water level in the sump pit. It’s like a beach
ball that “floats” on top of the water. When the water rises,
the float rises with it. When it gets high enough, a switch inside
the float closes and turns on the pump, draining the pit. When
the water drops low enough, the switch inside the float opens and
turns the pump off. And the cycle is repeated hundreds, thousands,
and even hundreds of thousands of times during the life of the
Why will it fail?
The float switch can fail for any number of reasons. Many
times the float simply gets stuck between the pump and the wall
of the sump pit. That’s because the pump vibrates slightly whenever
it runs, and can "walk” across the bottom of the pit, eventually
trapping the float between it and the side of the pit. Other times,
after so many up and down cycles, it just gives out and stops responding
to the rise and fall of the water in the pit. Often it stops working
while the pump is running. When this happens, the pump is left
switched on so that it runs continuously until it burns itself
out. You can’t do regular maintenance on a float switch, you can
only replace it once it fails.
What can you do?
Install one of our Electronic Pump Switches. They're
inexpensive and easy to install, and you won't need a plumber to
do it. Any of our Electronic Pump Switches will do what a float
switch does, only much, much better. The
float switch hasn't changed much in the 75 to 80 years it’s been
used to control sump pumps. It is a mechanical device that has
to eventually wear out. Our Electronic Pump Switches, on the other
hand, use reliable microprocessor technology to control your pump. In
fact, our Electronic Pump Switches are so reliable we give
them a lifetime warranty when used under
normal conditions! We can do this because
our switches use
reliable solid state components to detect the presence of water,
so there's nothing to wear out!
