"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."

"Jesus did a great job: the house builders installed irrigation that tapped into the water main before the valve into the house, so that a leak in the irrigation system (plastic pipes) meant that we had to shut off water to the house at the water meter at the curb. We had a leak in a buried plastic irrigation pipe, and so we had to do without water until it could be fixed. Jess installed a copper pipe to split off from the main pipe and added a valve, and mated copper pipe to the irrigation plastic pipes, so that if there were a future leak in the irrigation system, it's easy to shut that off w/o having to shut off the whole house. Jesus was on time, did a great job, fixed things quickly, and I'd definitely hire him again."

"Went above and beyond with my new kitchen sink installation. Francisco found some issues with the previous installation (done by a family friend, not a pro) and was very honest with his recommendations/prices and fixed the issues properly. The new sink looks great, lingering issues are finally fixed and best of all, the wife is very happy."

Sump Pump Installation FAQs, 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.

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.

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.

Yes, many modern water pumps are designed with energy efficiency in mind. Look for pumps with high efficiency ratings or those with an Energy Star certification. These pumps consume less power and can reduce your utility bills. Additionally, variable-speed pumps are more efficient since they can adjust the flow based on demand, providing significant savings over time.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.
