"Diagnostician/Estimator and Plumbing team were just excellent. Sewer work and team very good, but also very pricey. Repairs on system were well done - crawlspace access area was damaged to extract the old sewage tank. Damage is still being repaired by homeowner. Harts rebated some cost to cover access damage. All Harts team members were fully vaccinated, wore masks, and were great to work with. Harts completed work within 1 day within quoted costs. New sewer pump alarm system system malfunctioned right after the install was finished - Harts sent a repair tech out to fix it on next day - excellent service - fixed the twisted tank float problem - no charge. Building inspector noticed new sump pump was tilted and alarm wiring was not properly affixed to the house - minor issues, I would hire Harts again but negotiate hours and pricing ."

"The individual who visited and prepared the proposal, as well as the installation team, arrived on time, provided helpful and accurate detail on what work would be performed, how, and when, and executed their work in an organized fashion. The installation crew did a thorough cleanup and completed their work on time. Although the bid was competitive compared to others, the work was still more expensive than I felt it should be considering that work took less than a day and used few materials (aside from a sump pump which accounted for 1/3 of the cost). The only negative was that the financial office was unprepared with the necessary paperwork at the time of the work, causing some slight confusion. However, they did get this sorted out quickly and the minor issue did not at all delay or interrupt the work."

"As usual, they did an outstanding job. This is the fourth time I've used Rain Pros services (drain tile installation, addition of topsoil to roll and level lawn, over seed existing lawn). Their crew is hardworking, prompt and professional. They are very knowledgeable and skilled. I have never been disappointed."

"We had just completed a deck and patio project and the old hose bib location was just inches from the floor of the deck. We needed it moved to a more convenient location. I called a local Plumber we'd used before and got a bid, which cost $49.00. The total I was quoted to move the hose bib was $484. I about fainted when I heard this. The old hose bib just needed to be capped off and the new hose bib location was adjacent to a bathroom with the crawl space 2 feet away. I knew this was going to be an easy-peasy job, but not almost $500 worth. So I looked up a Plumber on Angie's List, which is what I should have done in the first place. I was so surprised when I saw an A rated Plumber, JM Plumbing and Mechanical with a coupon for of all things, a hose bib relocation or install for $175.00, a $300.00 value. I bought the coupon on the spot and spoke to the owner 2-days later and scheduled the job this morning. He showed up spot-on the time we scheduled the job and was done in 20 minutes. I am still pinching myself at how quick and easy this was plus now I have found a Plumber for life.
Thank you Angie's List and Thank you Jerry Morse of JM Plumbing

Sump Pump Installation questions, answered by experts

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.

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

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

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.

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.
