D-Series | DH071 & DR071 Grinder Pump Station

E/One DH071 grinder pumps station

The E/One model DH071/DR071 simplex grinder pump station is an ideal choice for single-family homes: it can be installed in the yard or in the basement and provides 70 gallons of capacity. Grinder pumps collect wastewater from the home and send it to the central sewer and/or treatment system through small-diameter pipes.

This model was previously known as the Farrell 210, Model GP 210 or Model GP 2010.

About the DH071/DR071 Grinder Pump Station

Jim Welsh describes the DH071/DR071 grinder pump station:


The DH071/DR071 grinder pump station consists of a pump and a tank with a dry accessway. The grinder pump uses integrated level-sensing pressure switches instead of floats — the "core"-style pump is compact and easily removed for service if needed.

  • The DH071 is the “hardwired,” or “wired,” model where a cable connects the motor controls to the level controls through watertight penetrations.
  • The DR071 is the “radio frequency identification” (RFID), or “wireless,” model that uses wireless technology to communicate between the level controls and the motor controls.

The tank is made from tough, corrosion-resistant HDPE and provides 70 gallons of capacity. A single DH071/DR071 is ideal for one, average single-family home and can be used for up to two homes where codes allow and with consent of the factory. The DH071/DR071 can accommodate flows of 700 gallons per day. 

Stations are available for indoor and outdoor installations. Outdoor stations accommodate a wide range of depths, suitable for both warm and cold climates (refer to drawings above).

E/One requires the installation of its stainless steel UNI-LATERAL to prevent backflow from the sewer system from entering the grinder pump station.

Inlet Connections: 4" inlet grommet standard for DWV pipe. Other inlet configurations available from factory.

Discharge Connections: Pump discharge terminates in 1-1/4" NPT female thread. Can easily be adapted to 1-1/4" PVC pipe or any other material required by local codes.
