"I was really impressed with Phill's Pluming, from the time I requested a quote through the final installation. Phill responded to my request quickly, and researched the facuet I was looking for. Within the same day I had a quote. He ordered the facuet and it was installed with a couple of days. His employee, Joe was on time, wore a face mask, covered his shoes, made sure my floor was covered, and completed the installation quickly. I was looking for a go to Plummer that I could trust and rely on, and I definitely found one. - Lml, Irvine"

"This is the 5th or 6th time Western Rooter and Plumbing does a plumbing job in my house over past 10 years. They installed softwater tank, replaced waterheater, fixed plumbing, and more. Always excellent"

"Parker was great. Installation was very well done and looks great. Clean up was very good. Bill Metzger Plumbing arrived when promised. Responded to phone calls promptly and were extremely professional. I had the unfortunate experience of call some competitors who never showed up for an appointment and we recommended by the manufacturer. Wish I had called Bill Metzger Plumbing first."

Sump Pump Installation FAQs, answered by experts

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

DIY is possible for simple repairs. Professional services ensure proper diagnostics and long-term reliability.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

Common problems include motor failure, clogged discharge lines, and float switch malfunctions. Regular maintenance prevents many issues.
