When you flush your toilet, you probably don’t think about where the waste goes, or how it’s pumped into a sewage line. However, this is something that plays a huge role in your lifestyle each and every day. In homes that are situated below septic or sewer lines, gravity can’t be applied to move waste. That’s where a sewage pump comes in.
What is a Sewage Pump?
A sewage pump is effectively a pump that’s used to move sewage liquids and solids between one location and another. In the case of a house, sewage is usually pumped from the basement of the house into the main sewage line.
Sewage pumps can either be manual or automatic. Manual sewage pumps need to be turned on every so often, though usually aren’t recommended due to the possibility of sewage overflow. Automatic sewage pumps, in contrast, function with the help of a float switch.
How Sewage Pumps Work?
Sewage pumps are centrifugal pumps. They also are specially designed in order to allow solids to pass through them without clogging the pump itself. When the pump is turned on, the motor rotates the impeller, which creates enough pressure to push water into the impeller and from there into the discharge pipe.
You may wonder how the pump knows when to pump sewage in the first place, or how the sewage tank keeps from overflowing. This is largely thanks to a float switch. This switch floats upward as the number of sewage increases in the tank. Once the sewage reaches a certain level, then the float switch turns on the sewage pump, which then allows it to be pumped out of the tank.
Float Switches for Sewage Pumps
One of the most important parts of a sewage pump is the float switch, which allows the pump to actually begin pumping. The FN20 Mechanical Sump Switch is commonly used in Home applications like sump pumps and basement pumps. This sump float switch may also be used for septic tanks and ejector pumps.
