Customers say: True professional

"Matt and his team arrived on time and were in and out sooner than I expected. They replaced two faucet,s, installed two new shut off valves. They also installed a ball valve and replaced a boiler drain faucet at the main water line into the house all in little over an hour. They left no mess and were polite and courteous. They did this at a very fair price and with no surprise charges. I would certainly recommend Matt's Pro Plumbing."

"The work done was excellent. The plumber was also extremely personable and professional. The only thing I had a problem with was the high price. I guess I'm not used to paying someone else for jobs I used to be able to do myself."

"I asked for three quotes from Angie's List. I had chosen a large home services company from the list, and Angie's supplied me with two other names nearby. Borselle was the only contractor who called back and discussed the project. His call was very prompt, within a day. We asked him to replace a toilet with a quality water-saving model, and he was very knowledgeable and helpful in choosing a model, which he purchased and brought with him. It was a great choice. He also was helpful in answering other questions that we had. Plus, his price for the replacement was one-third less than the giant home repair company that had done similar work a year before. Borselle is definitely our new go-to plumber."

Sump Pump Installation FAQs, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

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.

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.
