Effluent Pump Installation Guide

Effluent pumps, also known as sewage pumps, are essential components in residential and commercial buildings. They are designed to pump effluent, or wastewater, from a septic tank to a drain field or a sewage system. This article provides a comprehensive guide on how to install an effluent pump, including the necessary tools, steps, and safety precautions to consider.

Understanding Effluent Pumps

Before diving into the installation process, it’s crucial to understand what an effluent pump is and how it works. Effluent pumps are submersible pumps that push wastewater from a building into a septic tank or a sewage system. They are typically used in homes or businesses where the plumbing system is below the level of the city sewer line or septic tank.

Tools and Materials Needed

Before starting the installation process, ensure you have the following tools and materials:

  • Effluent pump
  • PVC pipes and fittings
  • PVC cement and primer
  • Hacksaw
  • Adjustable wrench
  • Screwdriver
  • Level
  • Tape measure
  • Protective gloves and eyewear

Effluent Pump Installation Steps

1. Safety First

Before starting the installation, ensure you are wearing protective gloves and eyewear. Always disconnect the power before working on the pump to avoid electrical shock.

2. Prepare the Installation Site

Ensure the area where the pump will be installed is clean and free from debris. The pump should be placed on a solid, level surface to ensure stable operation.

3. Assemble the Pump

Follow the manufacturer’s instructions to assemble the pump. This typically involves attaching the pump to the discharge pipe and securing it with a clamp.

4. Install the Pump

Lower the assembled pump into the septic tank or sump pit. Ensure the pump is level and the float switch can move freely without obstruction.

5. Connect the Discharge Pipe

Connect the discharge pipe to the pump and run it to the drain field or sewage system. Use PVC cement and primer to secure the pipe fittings.

6. Test the Pump

Once the pump is installed and the discharge pipe is connected, fill the tank with water to test the pump. The pump should start automatically when the water level reaches the float switch.

Common Mistakes to Avoid

While installing an effluent pump may seem straightforward, there are common mistakes that can lead to pump failure or inefficient operation. These include:

  • Not using the correct size of pump: The size of the pump should be determined by the volume of wastewater to be pumped and the height it needs to be lifted.
  • Not installing a check valve: A check valve prevents wastewater from flowing back into the tank when the pump is off.
  • Not securing the pump: The pump should be secured to prevent it from tipping over or moving during operation.

Professional Installation

While it’s possible to install an effluent pump yourself, it’s often recommended to hire a professional. Professionals have the necessary experience and tools to ensure the pump is installed correctly and safely. According to HomeAdvisor, the average cost to install a sump pump is between $1,000 and $1,500, including the cost of the pump.


Installing an effluent pump is a crucial task that requires careful planning and execution. By understanding the function of an effluent pump, gathering the necessary tools and materials, and following the step-by-step installation guide, you can ensure a successful installation. However, due to the complexity and potential risks involved, it’s often recommended to hire a professional for this task. Regardless of who installs the pump, regular maintenance is essential to ensure its longevity and efficient operation.
