"My well pump froze after 26 years of service and an inquiry to my previous well service company was not answered. I then reviewed a few companies before contacting Ramiro and discussing options for the replacement. I decided to go with an exact replacement Goulds J10S pump that I acquired and have one of Ramiro's team install it. The scheduling and installation went without a hitch. I am pleased and highly recommend Quality Pump Service."

"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"Everything looks good after the work was done. I can finally close my bathroom door. I appreciated the fact that the foreman Erick Baez, went over what was done as they were done. I also appreciated that the two installers Manny Erickson and Jesus Villagomez also communicated with me after they were done to reassure that they did a proper job installing the jacks. Very good to know how the process was going. Great job."

"Went well. Poor communication regarding after install. Apparently I need to have testing done by another agency and also the city needs me to schedule a full day for them to come inspect and close permit. I was not made aware of either of these in advance. Otherwise service was prompt, professional and just as we needed."

"There was not much communications between David Carney and the installers. The installers had to come back second time to complete the job and the quality agreed. David Carney has a superior salesmanship. However, after the deposit was made, I was not able to reach David for questions. He did't answer your voice mails and email or going through his office. c"

"Bryson Heating and Air showed up on time! Gave me a reasonable bid. Installed a new unit! Cleaned out my old ductwork and took time after to show me how to clean my unit. Since I live in the country, “we got dirt!”! Joe himself over saw the whole process. Highly recommend! PS Joe also sold me a 25 Kilo Volt Solar panel grid. Saves me over $1000 am month. Solar is the way to go! Anything to save money right now."

Sump Pump Installation FAQs, answered by experts

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.

To maintain your sump pump, start by checking it every three to four months to ensure it’s in working order. Clear any debris from the pit because blockages can prevent the pump from operating efficiently. You should also test the pump by pouring a bucket of water into the pit. If it turns on automatically and drains the water, it’s functioning correctly. Inspect the discharge line for clogs, and ensure it directs water away from your home. Once a year, clean the pump itself, and consider having it professionally serviced for optimal performance.

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.

You should be fine. Most high-grade grinder pumps have a 24-hour holding capacity within the tank. You can continue to use the facilities so long as the power outage does not stretch into days. In a worst-case scenario, attach a generator to the grinder pump, providing it has sufficient electric capacity.

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.
