Sump, Sewage, & Effluent Pumps

From basement water management to residential wastewater removal, Watermain Supply stocks a complete range of Baker DuraMAC sump, sewage, and effluent pumps for residential and light commercial applications.

Sump pumps handle groundwater intrusion and basement flooding. Sewage pumps are designed to move waste solids up to 2 inches in diameter from below-grade bathrooms and laundry rooms. Effluent pumps move greywater and lightly treated septic system discharge to drain fields. Grinder pumps handle the toughest applications where solids must be fully macerated before transport.

All Baker DuraMAC pumps are available in cast iron or thermoplastic construction, with HP ratings from 1/4 to 1/2 HP. Replacement parts and accessories are in stock for fast service and repair.

Sump, Sewage, & Effluent Pumps

Shop the complete lineup of Baker DuraMAC sump, sewage, effluent, utility, and grinder pumps at Watermain Supply — your authorized dealer for one of the most trusted names in residential, commercial, and industrial wastewater management.

Whether you're protecting a basement from flooding, pumping raw sewage from an ejector pit, moving septic effluent to a drain field, clearing standing water from a job site, or grinding solids into slurry for long-distance force main delivery, we carry the right pump for the job in stock and ready to ship.

Our sump pump selection ranges from budget-friendly 1/4 HP thermoplastic models like the 5025PTSP to heavy-duty 1/2 HP cast iron units like the 5050CVSP pushing 70 GPM, plus complete pre-assembled sump systems, crawl space packages, clear water basin kits, and battery backup pumps that keep you protected when the power goes out.

For sewage applications, the DuraMAC 5050CTSJ series features rugged cast iron construction with non-clogging stainless steel vortex impellers that pass 2" solids at up to 80 GPM, available as standalone pumps or complete simplex packages with basin, cover, check valve, alarm, and discharge piping ready for drop-in installation.

Our effluent pumps handle septic and greywater loads from 1/3 HP residential units up through high head models pushing 100 GPM at 50 feet of vertical lift, while the commercial 404011EF and 405012EF series scale from 4/10 HP to 2 HP for demanding industrial effluent and dosing applications. The 5020PUUP portable utility pump gives you a lightweight, go-anywhere solution for removing standing water from window wells, pools, flooded garages, and construction sites with a garden hose adapter and 1/4 HP motor.

When standard sewage pumps can't reach, our Baker grinder pumps — from the 1 HP 110911GRP to the 2 HP 120212GRP — macerate all solids into fine slurry and push it through small-diameter 1-1/4" force mains over long distances and extreme head conditions that would choke a conventional pump.

Every pump we sell is factory-built by Baker Water Systems with thermally protected motors, stainless steel or cast iron internals, and your choice of tethered, vertical, or no-switch configurations for control panel integration across 115V and 230V options.

We also stock the full range of DuraMAC accessories including float switches, mounting blocks, basin extensions, check valves, pump leads, and replacement parts so you can install, maintain, and repair your entire system from a single source.

As an authorized Baker dealer, Watermain Supply delivers competitive pricing, expert technical support for pump sizing and system design, and fast nationwide shipping — because when water is rising or sewage is backing up, every hour counts.
