"Excellent service. I had a sump pump system put in 10 years ago by Rescon. Never had any problems with it, worked great. This weekend with all the rain the pump stopped working. I called there emergency line and a service technician called me back in less than an hour. They were at my house in less the 2 hours fixing my pump. They did charge me an emergency dispatch fee for the service call but I guess that s expected on a weekend. Overall it was excellent service and I am very happy I chose this company."

"George and his team did an excellent job with the install. I received quotes that were much higher for the same project and similar systems. As busy as George was he always answered my questions leading up to the install and was there right when he said he would be. George even helped me plumb a water line to my refrigerator and didn't charge me for the material he used! I have already recommended Absolute Water Systems to a friend and will certainly be using them for any future projects."

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

"We were so happy with the kitchen and master bathroom remodel that Todd did for us that we hired him again to remodel our downstairs bathroom. Todd gutted the old bathroom down to the studs and rebuilt the floor in order to remove water damaged boards from a prior leak as well as accommodate the new curb less shower pan. Todd was very thoughtful and had some good design & layout suggestions and helped us work thru other challenges like how to route/hide things we didn’t think of such as vent pipes. Todd found and installed new window trim and doors that also closely matched the rest of the house to help maintain consistency throughout. He installed new tile on the floor, shower walls, and subway tile halfway up all the remaining walls. All of the lines were perfect again and he did a fantastic job. We have received many compliments on the bathroom and are thrilled with how it turned out. Todd is a pleasure to work with and we highly recommend him and his work."

Sump Pump Installation FAQs, answered by experts

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.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

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.

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.

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.
