A septic tank pump is a small electrical water pump that can be submerged in wastewater. Each septic tank pump has a float switch that turns it on and off when it fills with water. A septic pump is required when you need to pump sewage to a higher level.
A septic pump can be installed into your existing septic tank or in a pump station near the septic tank. Depending on how many chambers your septic tank has will determine which septic tank pump you need.
Other things to consider when purchasing a septic tank pump is the need for septic tank filters, different alarms and controls, and where you would like it be installed.
