Sewage ejector pump
repair & replacement.

If you have a bathroom, laundry, or wet bar below your main sewer line, a sewage ejector pump (often confused with a sump pump) quietly moves wastewater up and out, and you really notice when it stops. We install, replace, and repair sewage ejector and grinder pumps across the Inland Empire, and we are glad to help you sort out which one you need.

What a sewage ejector pump does

When wastewater has to go up before it can go out.

Most homes drain by gravity: wastewater flows downhill to the sewer. But when a bathroom, laundry room, wet bar, or basement fixture sits below the level of the main sewer line, gravity can't do the job. A sewage ejector pump collects that wastewater in a sealed basin and pumps it up to the sewer or septic line.

If you have a below-grade bathroom or laundry in the Inland Empire (found in some hillside homes, sunken additions, and the rare home with a basement), that fixture almost certainly relies on a sewage ejector or grinder pump. When it fails, the fixtures back up or stop draining, and you may notice odor or a pump that runs constantly.

Clearing up the confusion

Sump pump or sewage pump?

A lot of homeowners call us about a "sump pump" when what they actually have is a sewage ejector pump. It's an easy mix-up: both sit in a pit and both pump liquid upward. But they handle very different things, and the fix is different too.

A sump pump moves clean groundwater and stormwater away from a crawl space or foundation. It keeps the structure dry. See our sump pump service →

A sewage ejector pump (and its cousin the grinder pump) moves wastewater and solids from a toilet, shower, sink, or washer that sits below the sewer line. It's part of your drain system, sealed and vented, and it handles what a sump pump never should.

Not sure which one you have? That's completely normal. Describe the symptom (where the water is, what fixture it's near, any odor) and we'll identify it for you on the phone or on site. Call (909) 312-4516.

Freddy Lopez and Anthony were absolutely incredible. I just purchased a home that was remodeled but came across issues with one of the bathrooms. I had Roto rooter come out who couldn’t fix the issue. I found Sweetwater on Google which had great reviews…

Common Questions

Frequently asked questions.

What's the difference between a sump pump and a sewage ejector pump?
A sump pump removes clean groundwater and stormwater to keep a crawl space or foundation dry. A sewage ejector pump moves wastewater and solids from a toilet, shower, sink, or washer that sits below the sewer line, pumping it up to the main sewer. Many people use "sump pump" for both: if you're unsure which you have, describe the symptom and we'll identify it for you.
How much does sewage ejector pump service cost?
Sewage ejector pump cost depends on whether you need a repair, a full pump replacement, or a new basin installation. We look at the job first, then give you your options, each with one flat-rate price. Our customers tell us our pricing is honest and fair.
How do I know if my sewage ejector pump is failing?
Common warning signs: a below-grade toilet or shower that drains slowly or backs up, sewage odor near the pump basin, a pump that runs constantly or never shuts off, gurgling drains, or an alarm sounding. If you notice any of these, stop using the fixtures that drain to the pump and call before the basin overflows.
