How Does a Sump Pump Work?
Sump Pump Basics
Sump pumps are placed in a small pit where water can collect. When the water reaches a certain depth, the sump pump turns on and pumps the water outside away from your house.
Water is pumped out of your basement through a discharge pipe. The pipe needs to be carefully located so water doesn’t run back to the foundation. There’s a check valve inside the pipe so water can only leave your home and not come back in.
Sump pumps have a motor. The motors vary between 1/4 and 1 horsepower. The device is connected to your home’s electrical system. Some sump pumps have battery backup in case your home loses power. The motors have a fan-like part that pushes the water out of the pit and into the discharge pipe.
Sump Pump Design
There are two types of sump pump designs called pedestal and submersible. Submersible sump pumps are quieter than pedestal ones, but they are more expensive. The motors on pedestal sump pumps never touch water whereas submersible sump pumps have waterproof covers.
Sump Pump Maintenance
You should inspect your sump pump once a year. Unplug your sump pump, and take its cover off so you can look inside. Clear any debris you find to prevent clogs. If the water looks greasy, your sump pump’s motor may be damaged. Pull the pump out, and clean its inlet screen and fan-like device. Also, check that the float is on top of the water and can move freely.
