Installing an ejector pump typically costs around $2,500, with most homeowners spending between $1,200 and $4,000 depending on the project scope. If you’re adding one for the first time—especially in a basement without existing drain lines—costs can run as high as $6,500.
Ejector pumps are essential for moving wastewater from below-grade spaces like basement bathrooms or laundry rooms up to your home’s main sewer line. Without one, sewage can back up during heavy use or flooding, causing thousands in cleanup and repair costs.
There are two main types of ejector pumps: sewage ejector pumps, which are more affordable and common, and grinder pumps, which are stronger but pricier. Pump type, installation complexity, and capacity needs are the biggest cost drivers.
While you might save money with a DIY installation, I strongly recommend hiring a licensed plumber—especially if you’re drilling into concrete or installing a system from scratch. A poorly installed ejector pump can lead to messy failures and ongoing plumbing issues.
In this guide, I’ll break down everything you need to know about ejector pump costs, pump types, installation considerations, and whether DIY is worth the risk.

Key Takeaways
- Depending on the project’s scope, you can pay anywhere from $630 to $6,500 to install an ejector pump.

- Ejector pump installation isn’t easy, so I recommend hiring a professional.
How Much Does It Cost to Install an Ejector Pump?
The cost to install an ejector pump is $2,500 on average, but you could pay anywhere between $630 to $6,500 with labor, depending on the size and type of pump and the scope of the project.
You’ll pay around the national average if you’re replacing an old ejector pump. If you’re installing one for the first time, you’ll likely see a bill closer to $6,500, as you need to install drain lines, drill into the concrete, and then re-concrete the area.
You could potentially save money with a DIY approach, but I don’t recommend it. Without professional installation, your pump might not work correctly, resulting in raw sewage on the floor and other plumbing problems. A DIY residential unit costs between $100 and $4,000.
| Low | National Average | High |
| $630 | $2,500 | $6,500 |
How Do Ejector Pump Costs Differ by Type of Ejector Pump?
Ejector pump installation costs depend on the type you install—a sewage ejector pump or a grinder pump. Both move wastewater out of a basement bathroom or laundry room, but sewage ejector pumps are the more affordable option, averaging between $100 and $2,150.
Grinder pumps shred the waste before it’s discharged into the sewer system, and they can handle more waste at a single time than sewage models. They tend to cost around $1,000 to $4,000, but you could pay as much as $6,500.
Submersible sump pumps aren’t ejector pumps—they keep groundwater out of your home, preventing basement flooding. They average between $100 and $3,500.
| Type | Average Price |
| Sewer ejector pump | $100 – $2,150 |
| Grinder pump | $1,000 – $6,500 |
| Submersible sump pump | $100 – $3,500 |

How Does Material Affect Ejector Pump Pricing?
Ejector pumps come in various materials, including cast iron, plastic, stainless steel, and a combination of plastic and cast iron. Plastic pumps range from $150 to $500. Cast iron units are much more durable than plastic, but they often cost between $200 and $2,000.
| Material | Average Price Range |
| Cast iron | $200 – $2,000 |
| Plastic | $150 – $500 |
| Plastic and cast iron | $200 – $700 |
| Stainless steel pump | $250 – $850 |
What Other Factors Impact Ejector Pump Cost Estimates?
The type and size of the ejector pump are the biggest cost factors, but the maximum capacity and brand can also impact the total price.
Brand
In some cases, it’s more cost-effective to buy the sewage ejector pump yourself and then hire a plumber to install it. Wayne is an affordable option, ranging from about $180 to $420. While Zoeller’s ejector pumps start at around $220, they can cost up to $1,500.
These are some of the top brands and their average costs:
| Brand | Average Cost |
| Everbilt | $225 – $850 |
| K2 | $230 – $530 |
| Superior | $200 – $350 |
| Wayne | $180 – $420 |
| Zoeller | $220 – $1,500 |
Maximum Capacity
The gallons per hour (GPH) indicates how much water an ejector pump system can move. An ejector pump with a higher GPH can transfer more water farther than a model with a lower GPH. However, more capacity also means higher costs.
A 5,400 GPH ejector pump, which costs an average of $450, can move wastewater up to 10 feet, which covers most basement ceiling heights in American homes.
This table breaks down common pump capacity sizes and their associated price ranges:
| Gallons Per Hour (GPH) | Average Price |
| 3,000 | $200 – $250 |
| 4,500 | $300 – $350 |
| 5,400 | $400 – $500 |
| 6,600 | $800 – $850 |
| 7,200 | $850 – $1,200 |
What Are the Benefits of Installing an Ejector Pump?
You need a sewage ejector pump if you have a basement bathroom or laundry room with plumbing below the sewer line.
On the upper floors, gravity moves waste from your home to the sewage system. However, since basements are below grade, gravity isn’t an option. Without an ejector pump, sewage could back up into your basement in the event of clogs or floods. If this happens, you’ll have to pay thousands of dollars in cleanup and repairs.
Should You Hire a Pro To Install an Ejector Pump or DIY?
It’s not easy to install an ejector pump on your own, especially if you’re not replacing an existing unit. Installing an all-new system requires extensive work, including drilling through up to 30 inches of concrete. I highly recommend working with a professional plumber for this job.
To find the right plumber for your ejector pump installation:
- Compare and research local experts. Compare plumbers’ reviews on trusted review sites. Double-check that they have the appropriate licenses and insurance for your area.
- Get quotes and ask for recommendations. Gather at least three quotes from reputable professionals. Review what the prices include. Talk to the plumbers about your needs so they can make recommendations on the best size and type of ejector pump for your home.
- Sign the contract. Choose the best plumber for the job and your budget. Read the contract fully before signing.
- Schedule your appointment. Installing an ejector pump usually takes about two to four hours but complex jobs could take up to 10 hours. The plumber may need to visit your home several times to finish the installation.
So, Is Installing an Ejector Pump Worth It?
Ejector pumps remove sewage from below-grade rooms, such as a bathroom or laundry room in the basement. If you don’t have a pump and have one of these below-grade rooms, sewage could back up, overflow in your basement, and cause thousands of dollars in damage. Ejector pumps aren’t legally required, but they’re absolutely worth the cost. To make sure your home is protected, I recommend working with a professional plumber to install your new ejector pump.

Frequently Asked Questions About Ejector Pump Cost
How long does an ejector pump last?
The average ejector pump has a lifespan of seven to 10 years, but with proper maintenance, a pump can last up to 30 years or more.
To extend the life of your unit, inspect it every three months. Check for signs of leaks, cracks, and damage. Both the pump and the discharge pipe should be secure. Plan to clean your ejector pump at least once a year to prevent clogs, as debris and waste can build up.
Before cleaning, always turn off the water supply and circuit breaker to avoid injury. Wearing gloves, remove the ejector pump from the basin. Clean out the components with a brush and mild detergent. You can also use this time to tighten connecting elements, clean the vents, check the seals, and test the float switch.
You can extend an ejector pump’s lifespan further by being mindful of what you flush. Sewage ejector pumps can handle toilet paper, human waste, and water. They can’t handle baby wipes, dental floss, grease, chemicals, or other items. Flushing inappropriate items can cause clogs and weaken the pump over time.
What happens if an ejector pump fails?
If an ejector pump fails, you’ll see leaking raw sewage. Call a professional immediately. Raw sewage is hazardous, so never try to tackle the job yourself.
An ejector pump can fail for several reasons, including:
- Incorrect installation: If the professional cuts corners during installation, it could lead to leaks.
- Wrong capacity for the home’s needs: If the ejector pump isn’t big enough to handle the waste, the sewage will eventually back up.
- Broken or bypassed float switch: Never bypass the float switch long term. It causes your pump to run nonstop, and it will break down faster. If the float switch is broken or jammed, it’s an easy fix.
- Clogs: Obstructions can cause the pump to continuously operate. An alarm should sound, but if it’s ignored, the sewage may back up. The unit could also overheat, resulting in the motor burning out.
You should call a plumber if you notice your ejector pump is running constantly, won’t start easily, or is making strange sounds. Listen for alarms which could indicate an issue with clogs or the float switch.
What is the difference between an ejector pump and a sump pump?
An ejector pump removes waste from basement bathrooms and laundry rooms in residential buildings. Gravity helps remove waste in the rest of your home, but basements are below grade. As a result, bathrooms and laundry rooms in this space need an ejector pump to force the sewage away from the home.
The main difference between a sump pump and an ejector pump is the presence of sewage. A sump pump keeps outside groundwater and rain from entering your basement and home, preventing flooding.
If you’re not sure which you need, how your house would benefit from a sump pump or ejector pump, or what size is right for you, talk to a plumber. They can walk you through the best options for your needs and budget.
