"I was incredibly pleased with Emmanuel and his team when they recently installed my sump pump. They were punctual, courteous, and professional throughout the entire process. They took the time to explain the installation process in detail and were quick and efficient with the actual installation. When they were finished, the area was left clean and tidy. I have no hesitation in strongly recommending these plumbing professionals for any of your plumbing needs.

"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."

"Fito Plumbers installed a new sewer line at my house. I appreciate good customer service when I see it, especially when it is with a contractor. My experience with Fito Plumbers was a positive one from the very beginning. From the quote, all the way through the final signoff Fito's team was great. Fito was honest and kept in communication with me over the one month period that it took to get the permits. His team showed up when he said they would, they were courteous and they respected my property. They did not kill one plant on my property which is a first. They cleaned up at the end of each day and they restored the pavers to the point where I can not tell where they had to remove them. I also appreciate that Fito's team power washed all the utility paint markings not only on my property but in the street. My street is covered with paint from previous work by others. Overall, Fito Plumbers was competitively priced and went beyond expectations with the installation."

Sump Pump Installation FAQs, answered by experts

Yes, many providers offer warranties for new pumps and labor. Confirm terms before scheduling.

First, you can try unplugging the two sump pump cords, one for the motor and one for the float switch, then plugging them back in to reset the sump pump. You can also reset the sump pump by turning it off and back on at the breaker. Many sump pumps have a reset button, which you can press and hold for a few seconds to reset the device.

3/4 HP is stronger than 1/2 HP. Horsepower measures how much weight can be moved and how fast, or the power needed to move 550 pounds one foot in one second. 1 HP equals 550 foot-pounds per second, so the higher the horsepower, the heavier the load it can lift. While 1/2 HP is a standard, powerful option, 3/4 HP has the extra strength to handle heavier, larger doors with ease.

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.
