How to Install an Effluent Pump

Effluent pump is part of a septic system, responsible for pumping effluent from the pumping chamber to the drain field. The chamber also includes devices a water flow control an alarm. Septic systems usually work on the force of gravity, but a few specific terrains don't support the natural gravitational flow of wastewater. In such cases effluent pump is used to help the flow to the tank.

Installing an effluent pump is only moderately difficult and, using the tools, as per the steps mentioned below, you can go about the project with little difficulty.

Tools and Equipment:

  • Septic Tank
  • Effluent Pump
  • Trenching Shovel
  • 1.5 Inch PVC Pipe
  • Direct Burial Wiring
  • GFCI Breaker

Step 1: Dig a Trench

Start off your project by digging a trench which is around 12 to 16 inches in depth and wide enough to accommodate an approximately 1.5 inch PVC pipe. Use a trenching shovel to dig your trench. This is an inexpensive tool easily available from almost every hardware store. Start off digging from the rear side of the tank and go until you reach the distribution box (field line). While digging the trench, see to it that the pipe is kept as straight as possible so that the pump can push the waste material more easily. This will keep your pump working longer.

Step 2: Set the Submersible Pump

You require a septic tank which contains 2 different chambers so that the first one takes up the sludge and the other one holds the water. the submersible pump goes in the external chamber of your tank. However, it is worth noting that the first chamber needs to be checked and cleaned thoroughly on a regular basis so as to stop sludge from moving into the second chamber and clogging the pump.

Step 3: Attach the Drain Line and Set the Float Switch

After the installation of the submersible pump, attach the drain line to the outlet port and assure that the connection is stable and sound so as to avoid any difficult repairs once the installation is complete. The float switch, responsible for activating the pump once the set water limit has been reached, also needs to be set at this stage. The proper settings will be provided by the tank's manufacturer.

Step 4: Get the Wiring Done

Once these settings are complete, wire your pump using direct burial wiring to a GFCI (Ground Fault Circuit Interruption) breaker dedicated to the tank only. This provides safety from possible electrical shocks or any serious accidents. However, if wiring is not your area of expertise you should get professional assistance for this step.

Step 5: Test the Pump and Finish Up

After the installation is complete, it is important to test the pump. Add water to the septic tank, which should, if the installation is operating fine, activate the pump, push the water out and shut off. If this is the case, your effluent pump has been accurately installed and you should end the project by filling the trench back and covering the septic tank.
