Sewer ejector pumps make waste removal possible in basement-level spaces by lifting wastewater to the main sewage line. Sewer ejector pump installation may sound technical. However, knowing each phase of the setup process can help you make informed decisions and anticipate what professionals will be handling. Here, we’ll cover all the steps for installing a sewer ejector pump to keep your home’s plumbing system running smoothly.

Why Sewer Ejector Pump Installation Matters

A sewer ejector pump is key for any home with a basement bathroom, laundry, or setup where waste needs to be pumped up to a higher sewage line. Proper installation makes sure that wastewater is efficiently pumped away, preventing unpleasant backups and potential damage to your plumbing system.

A successful installation involves setting the pump in the right position, connecting it to the discharge and vent pipes correctly, and protecting it against backflow and system overload.

The Setup: Preparing for the Installation Process

The placement of the pump is a major factor before installation begins. The ejector pump needs to sit in a basin in the lowest section of your basement. When installing a new pump, creating this basin usually involves drilling a hole through the concrete. This hole is typically about 18 inches in diameter and 30 inches deep. It’s a dusty job requiring heavy-duty equipment, so professionals will handle it.

Once the basin is ready, the discharge and vent pipes must be positioned correctly. The discharge pipe is important as it will carry waste to the main sewage line. The vent pipe guarantees gases are vented safely outdoors. These connections require careful planning and adherence to local building codes to avoid sewage gas leakage and pressure issues down the line.

Connecting the Discharge Pipe and Installing the Check Valve

With the basin in place, it’s time to connect the pump to the discharge pipe. This step allows wastewater to move efficiently from the pump to your main sewage line. The discharge pipe is attached to the pump using a male-threaded adapter and PVC glue.

The check valve is then installed above this connection to allow water to move only in one direction—up and out of the basin. A check valve prevents wastewater from flowing back into the basin, helping avoid overload and maintaining consistent pump performance.

Technicians often use zip ties on the electrical cords to secure the connection and prevent the pipe from twisting or shifting. This helps keep them organized and safely out of the way.

Sealing the Basin and Attaching the Lid

Sealing the basin with a tight-fitting lid prevents unwanted odors and gases from escaping into your basement. After placing a self-adhesive gasket around the basin lip, the lid is bolted down with the provided fasteners and further sealed with a silicone caulk bead.

This process provides a long-lasting, gas-proof seal. Adding donut gaskets around the discharge and vent pipes reinforces the setup, keeping everything tightly sealed. Placing gaskets on the electrical cords further enhances the seal and stability of the system.

Running the Vent Pipe and Completing the Setup

With the basin sealed, the final step is to run a vent pipe from the basin to your main vent stack or an external vent. The selection of the vent depends on your local building codes.

This step completes the setup, allowing the ejector pump to safely expel wastewater while venting out gases. Testing the pump’s functionality and checking the valve’s operation complete the installation process.
