Grinder Pump Instructions

Pump Failure Alarm

When the unit is in alarm prior to the arrival of an authorized service technician, water usage must be limited to the reserve capacity of the tank.

To silence the alarm, please press the silence button on the bottom of the unit. The red light will remain on until a technician services the grinder pump.

For service, please contact the Northwestern Water & Sewer District office toll-free at (877) 354-9090.

Power Failure

Your grinder pump cannot dispose of wastewater without electrical power. If electrical power service is interrupted, keep water usage to a minimum. The alarm will not function during a power failure.

Periods of Disuse

If your home or building is to be unoccupied for longer than a couple of weeks, perform the following procedure:

Purge the System – Run clean water into the unit until the pump activates. Immediately turn off the water and allow the grinder pump to run until it shuts off automatically.

Duplex Units – Special attention must be taken to ensure that both pumps turn on when clean water is added to the tank.

Caution – Do not disconnect power to the unit.

General Information

In order to provide you with suitable wastewater disposal, your home is served by a low-pressure sewer system. The basic unit in this system is an Environment One grinder pump. The tank collects all solid materials and effluent from the house. The solid materials are then ground to a small size suitable for pumping as a slurry with the effluent water. The grinder pump generates sufficient pressure to pump this slurry from your home to the wastewater treatment receiving line and/or disposal plant.
