"Bryan and his team were able to complete my water heater replacement with timing that met my needs, and high quality work. They also changed out two valves that were leaking on a connected water line for me (for an additional charge). Pelkey Services work was efficient, clean, and met my expectations. I would work with them again, and recommend them."

"Recently, I had a sewer pump replaced. Ken was the installer. He throughly inspected the sewer pump and miscellaneous parts. He explained the work to be performed. Ken replaced the sewer pump system and cleaned up the work area. He explained Brocks warranty as well as Zollers warranty. Prior to leaving he made it clear for us to contact his office if we have any issues. Overall, Ken demonstrated professional skills, knowledge and did a high quality job. We would definitely contact Brock Mechanical for all our water related needs."

"I was so impressed by how professional and efficient Matt was. He came in to the house, looked at the area where the work needed to be done, went back out to the van and then grabbed everything he needed to complete the job. His work was very precise, thinking about the perfect placement for the filtration system so that we could maximize use of the remaining space in the cabinet down to the routing of the power cord and hoses. Matt’s work is so clean, I can’t wait to call him and Benjamin Franklin Plumbing for my next plumbing needs."

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.

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early. 

The cost to repair a sump pump ranges from $400 to $550, depending on the extent of the repair and your location. Minor repairs, like fixing a switch or replacing a float, can cost just a few hundred dollars. However, more significant issues, such as motor replacement or addressing electrical problems, may cost closer to $550. Keep in mind that regular maintenance can help prevent costly repairs, and if a sump pump is beyond repair, a full system replacement ranges between $650 and $1,400.

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 move wastewater and solid waste to the municipal sewer or septic tank. However, for fixtures located below grade (e.g., in a basement), gravity is not sufficient.

The purpose of a sewage ejector pump is to actively pump this wastewater and solid waste upward into the main sewer line. Without an ejector pump in this situation, wastewater would have no way to exit and would eventually back up, causing a sewage overflow or flooding in your basement. If all of your home's plumbing is on the main floor or higher, gravity can handle the drainage, and an ejector pump is not needed.

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.
