"They did get the job done. Problem was 2 weeks ago it was clogged with "flushable" wipes and yesterday another wad of wipes. I literally stopped using them before ever calling the plumbers realizing they were the issue. He fixed the clog free this time but insinuated the idea that it was my fault. Unless they got stuck in the pipes on the way to the basement not my fault for the second time. Unsure about hiring again."

"Tim gave us an honest evaluation of our existing water heater and options for repair or replacement. We decided to replace the water heater and Tri-State scheduled the next day. Installation was professional and l think Tim is the kind of craftsman you want representing your organization. The fact that you install the Rheem brand helped close the deal."

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.

Costs depend on pump type, labor rates, and the extent of repairs or installation needs.

Inspect the pump annually, test the float switch, and clean the discharge line to ensure efficient operation.

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.

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