"Tyler came out the same day, Fri, otherwise we would've had to wait until at least Monday with another plumber. He cleaned out the roots and was very respective of our property because the only access to the pump is through our master closet. After a thorough testing, it worked just fine until that evening when the pump came on and wouldn't shut off, so I just pulled the plug. It's supposed to turn on for only a short time (seconds) when waste water is present. Tyler came out the next day (Sat) and fixed the problem, which was that one of the floats in the basin was tilted on its side."

"I was very satified with the work done by M&M. M&M determined that my shut-off valves did not need to be replaced, just tighten. After the job was completed we reviewed some other work that I was thinking of doing and eventually hired M&M to complete this additional work."

"It ended up all that had to be done was plug in the existing sump pump in the new house we bought, but the service person was very nice and professional, and we weren't charge for the visit. They could have told us it wasn't working and we needed a whole new system, if they were dishonest. I can't speak to their actual installation, since we were lucky enough to not need it, but if we did need a new system I would certainly have them back."

"I called this company after having them recommended by a friend. Richard was extremely accomodating and professional. I work during the day so the only time I had was after 4pm. He helped me pick out the parts I needed online and picked everything up at home depot for me. He got my new faucet installed and all the old valves replaced quick and clean. Very pleased with his service, wouldn't hesitate to call him again."

FAQs for sump pump repair or replace projects in Knightsen, CA

Sump pumps last about 10 years with proper maintenance and prompt repairs. Several factors can influence your sump pump’s lifespan, such as usage, environmental conditions, and installation. Premium sump pumps with heavy-duty motors and quality components tend to last longer than lower-cost models. Pedestal sump pumps usually last longer than submersible models since they’re not constantly exposed to water.

A basement French drain is a drainage system installed in basements or around a building’s foundation to redirect water and prevent flooding. This system features a trench with a perforated pipe that catches and transports water away. These systems can crack, freeze, or clog, potentially resulting in flooding or strain on your sump pump.

You can use a sump pump in your yard to minimize pooling water and landscape damage, but it’s best used in conjunction with other drainage systems. This can include French drains, trench drains, underground downspouts, and other equipment. Proper lawn care, such as soil aeration and native plants, also aids with drainage.
