Macerator Grinder (Sewer Ejector Pumps)

Plumbing problems? We can help you!

Sewer ejector pumps come into play when plumbing fixtures are located below the main sewer or septic line, such as in a basement bathroom or laundry room. Gravity alone can’t move waste uphill, so these pumps are installed to collect and push wastewater up to the main line where it can flow out properly.

They’re a must-have for finished basements, lower-level additions, and any structure where the plumbing sits below grade. If your shower, sink, or toilet is in a basement, odds are you’re relying on an ejector pump to keep things flowing in the right direction.

Macerating vs. Non-Macerating Systems

Not all sewer ejector pumps come with a macerator or grinder. Some simply move the wastewater along. Others include grinding components that break down solids into a slurry before sending it out of the tank. This maceration process can be especially helpful in systems that handle waste from toilets or where longer pipe runs and clogs are more likely.

Whether or not you need a grinder depends on the setup. For a basic utility sink or washer drain, a standard ejector pump might be just fine. But for a full bathroom with a toilet, a grinder pump adds an extra level of protection against clogs and backups. We’ll help you decide what makes the most sense for your space, your plumbing layout, and your budget.

What Goes Wrong and How We Fix It

The most common issues we see with sewer ejector pumps are clogs, float switch failures, and worn-out impellers. Sometimes the pump stops working altogether because of an electrical problem or because the unit was installed incorrectly from the start.

Odors, water pooling in the tank, or toilets that gurgle or won’t flush in a basement bathroom can all be signs that your ejector system is struggling. We’ll inspect the unit, test the controls, and figure out what’s going on. If it’s a small repair, we’ll get it fixed on the spot. If it’s time for a replacement, we’ll walk you through the options and install something that fits the system

What to Expect During Installation

Installing a sewer ejector pump isn’t a simple swap. It involves cutting into the floor, setting a basin, connecting discharge and vent lines, and wiring the unit correctly. We also need to size the pump to the application so it performs well without short cycling or overworking.

If it’s part of a new bathroom addition, we’ll coordinate with your builder or contractor to make sure the layout supports proper flow and access. If it’s a replacement, we’ll make sure the new pump matches the tank and doesn’t leave you with an oversized or underpowered system.

Done right, a good ejector pump system is quiet, reliable, and keeps your basement plumbing running smoothly for years to come.
