Angel Gonzalez did a great job and was very professional. He advised us on good ways to clean our drains and keep them odor-free. Thank you for your excellent customer service, Angel!
When you need a sump pump
Which Inland Empire homes need a sump pump?
Most Southern California houses are built slab-on-grade and don't have basements. But homes with crawl spaces or partial basements and homes in flood-prone areas (low-lying parts of Riverside, Eastvale and Corona) benefit from sump pump protection during heavy rainstorms.
The Inland Empire gets little rain most of the year, and much of what it does get falls in a few heavy storms. Without a working sump pump, those storms can flood crawl spaces and damage HVAC equipment, electrical wiring, and structural framing.
Clearing up the confusion
Sump pump or sewage pump?
Many homeowners call us about a "sump pump" when what they actually have is a sewage ejector pump. Both sit in a pit and pump liquid upward, but they do very different jobs.
A sump pump (this page) 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. If your problem is a below-grade bathroom or laundry backing up, that's a sewage pump, not a sump pump. See our sewage ejector pump service →

Sump pump service
What we do for sump pumps.
We install, replace and repair sump pumps, and we add battery backups so the pump keeps running when the power goes out during a storm.
Signs your sump pump needs service:
- It runs constantly, or switches on and off over and over.
- It doesn’t turn on when water rises in the pit.
- It makes loud grinding or rattling noises.
- The crawl space stays wet after rain, or the pit stays full of water.
- The pump is old or rusted.
On a service visit, we test the float switch and the pump, inspect the check valve and the discharge line so the water actually drains away from the house, clean the pit, and test the battery backup if you have one. The best time to have your sump pump checked is before the rainy season. You get your options in writing, each with one flat-rate price, before any work begins.

Matthew Perez did a good job accessing the potential problems. He snaked the drain, removed my 50 year old toilet and installed a new toilet, supply line and 1/4 angle stop. The work was accomplished professionally and to my satisfaction
