Zoeller Pumps are an excellent choice when a pump is required to pump the effluent from the septic tank to the absorption area. The Zoeller Septic Tank Pump is located in a pump tank or dosing tank following the septic tank(s) and before the absorption area. There usually is also an high water alarm box located in the house (usually the basement or garage) that sounds when there is a high water level problem. Typically there is a reserve in the pump tank to enable water use in the house when the alarm sounds, but the issue needs to be addressed ASAP.
