A fully functional and efficient plumbing system depends on a sewage ejector pump. This device, also known as a toilet ejector pump, is specifically designed to pump wastewater in a basement up to the main sewer line or septic system. Unlike sump pumps, which deal primarily with clear water or rainwater, sewage ejector pumps are specifically engineered to handle solid and liquid waste from toilets, sinks, showers, and other plumbing fixtures.

According to Angi, the average national sewage ejector pump cost ranges from $100 to $6,500, with many homeowners spending $2,500. The cost to install a sewage ejector pump may be influenced by the brand, model, and size of the pump. Factors such as the complexity of the installation and the condition of the existing system can also impact the price, since sump pump plumbing and sump pump replacement costs may be necessary.

Factors in Calculating Sewage Ejector Pump Cost

Sewage Ejector Pump Cost

The cost to install a sewage ejector pump is determined primarily by the pump type, pump capacity and construction material, and local labor prices. The national average cost of $2,500 provides a good baseline, but local variations can significantly impact the final price. Factors contributing to the wide cost range include the specific needs of ejector pump basement plumbing, the extent of existing plumbing modifications, and the overall complexity of the installation process.

Pump Type

Different pump types come with distinct features and capabilities that cater to specific plumbing needs. There are a few different types of sewage ejector pumps, including battery-operated backup pumps, grinder pumps, sewage ejector pumps, and submersible sump pumps. A professional plumber can offer recommendations of the best type of pump for a home’s sewage or sump pump system.

The primary function of a sewage ejector pump is to push the wastewater to a higher level, where it can flow into the main sewer line or septic tank. This is critical when gravity alone isn’t sufficient to move sewage upward. The pump activates when the accumulated wastewater reaches a certain level in the basin and pushes the sewage from lower-level plumbing fixtures out of the home. Sewage ejector pumps are integral in preventing backups and maintaining proper sanitation.

Pump Capacity and Construction Material

The pump capacity and material play an important role in sewage ejector pump installation cost. Higher-capacity pumps, capable of handling larger volumes of water and solids, generally come with a higher price tag. The required capacity depends on factors such as the number of fixtures connected to the pump and the anticipated flow rates. Investing in a pump with the appropriate capacity ensures efficient wastewater removal but may contribute to a higher upfront cost.

A pump’s capacity is usually measured by gallons per hour (GPH) and a maximum flow rate or horsepower. The sewer ejector pump needs to have the capacity and horsepower to force the wastewater and solids up to the elevation of the sewer line. It’s recommended that homeowners consult with a professional to determine the pump size that will work the best for their home. Most systems operate with ½ horsepower and 5,000 GPH maximum capacity, but that estimate applies to an average-size home of 2,385 square feet.

Pump CapacityAverage Cost (Materials Only)
3,000 gallons per hour$200 to $250
4,500 gallons per hour$300 to $350
5,400 gallons per hour$400 to $500
6,600 gallons per hour$800 to $850
7,200 gallons per hour$850 to $1,200
11,400 gallons per hour$1,500 to $2,000

The construction materials used in the manufacturing of the best sewage pumps can influence both the performance and cost. Pumps made from durable and corrosion-resistant materials, such as stainless steel and cast iron, are more expensive but provide longevity and reliability, reducing maintenance and replacement costs over time. Cheaper materials like plastic may result in a lower initial cost but could lead to increased maintenance or premature failure, potentially outweighing the initial savings. Another option that appeals to many homeowners is a blend of plastic and cast-iron materials for a cost-effective yet durable solution.
