How much does an ejector pump cost?

Sewer ejector pump cost

A sewer ejector pump costs $850 to $3,000 on average for a replacement or $2,000 to $5,500 to install a new system. Ejector pumps cost $150 to $2,000 for the unit alone and remove wastewater from basement bathrooms or washing machines, pumping it into the septic tank or local sewage system.

Sewage ejector pump cost by material

The price of sewage ejector pumps depends on the material. Plastic pumps are lightweight, rust-proof, and inexpensive but break more easily than metal pumps. Cast iron pumps with thermoplastic bodies are better at resisting corrosion, especially if you have a water softener that uses salt.

Sewage ejector pump price by capacity

The cost of an ejector pump also depends on its capacity, or the rate at which it pumps water. The higher the gallons per minute (GPM) or gallons per hour (GPH), the more expensive the pump will be. You'll need a higher horsepower if you're further down the municipal sewer line.

Ejector pump installation cost factors

The cost to install an ejector pump depends on whether it's a simple pump replacement or a new install. If you're installing a new system, the contractor will need to cut out a slab, install new drain lines, and pour new concrete.

Ejector pump labor costs are $700 to $1,000 for a basic pump replacement, while new sewer ejector pump installation costs $1,850 to $3,500. New installations cost more because the contractor needs to break up any existing concrete in the basement, install new plumbing, and pour concrete afterwards.

Sewer ejector pump replacement cost

The cost to replace an ejector pump is $850 to $3,000 with materials and labor, which is less than a full installation of a new system. During a pump replacement, the plumber or contractor will remove and dispose of your old pump and install the new one.

Ejector pump vs. other pumps

Sewer ejector pumps and grinder pumps remove waste from a home and pump it into the local sewer system or septic tank. Sump pumps, on the other hand, prevent flooding by pumping water out of a basement.

Grinder pump

Grinder pumps cost $1,000 to $3,500 for the unit alone. This pump type also removes home waste like an ejector pump but grinds the waste before it enters the sewer system. Grinder pumps can handle more waste at one time and are typically used in commercial waste systems.

Sump pump

This pump type is meant to prevent flooding and water damage in homes and is not connected to the sewer system.

Sewer ejector pump FAQs

A sewage ejector pump is a sewer system pump that helps remove waste from basement drains. Homes with bathrooms and washing machines in the basement or septic tanks need an ejector pump to make sure the sewage system doesn't get backed up.

If you have plumbing in a basement or below the level of the community sewer line, you will need a sewer ejector pump. Without a pump, gravity will eventually cause an overflow. Smaller models can handle a single bathroom or washing machine, while larger pumps can handle multiple bathrooms.

Ejector pumps last 7 to 10 years on average but can last 20 to 30 years with regular inspections and proper usage. To help your pump last longer, prevent clogs by only flushing moderate amounts of toilet paper. Don't flush too much at once, and never flush wet wipes or feminine products.

Sewage ejector pumps shouldn't need any regular maintenance besides a yearly inspection as long as you're careful about what you flush. During the inspection, a plumber will clean the pump and oil the motor to make sure it runs properly.
