"Called the office and asked for an evaluation and estimate on the job. Replace pump and float with new fittings. Someone would be over to look at the issue in a few hours. Even sooner Wes showed up and evaluated the situation and current piping set up. Clearly stated what was needed and provided an estimate and time to complete the job. He and his assistant left and said they would be back quickly after picking up the necessary pump and supplies to complete the job and how long it would take. They came back as they said and began the project explaining the whole time what happened, and the improved check valve and pump replacement were more efficient and less likely to have issues when the float is attached to the pump. Wes was efficient, experienced and willing to explain what he was doing and why. Gave some wonderful tips on avoiding issues in the future and clearly was sincerely passionate about his work. When they were finished, we had a much better system for the sump and piping. I would highly recommend Best Flo as a company that delivers more than expected and highly competent, experiences associates to resolve issues you may have with sewer or plumbing issues."

"For years I have wanted to update my very old and inefficient American Standard cast iron boiler. I was very fortunate to find Mr Joe Burriesci the owner of Mayjac Plumbing who took the time to evaluate the best options, since the old boiler handled two apartments. We collectively decided to go with two Navien Combi Condensing Boilers, but the best part of the entire process was how meticulous the installation was done. From start to finish Mayjac Plumbing kept every promise and timeline made. I highly recommend Mayjac Plumbing..."

"Every time it would rain the side of my yard would flood and get into my house. A close friend recommended Napolitano Brothers Contracting. Jim, James, and Michael Napolitano were great to work with. They installed a exterior drainage system and also water proofed the side of my house. After, I hired them to do a paver patio and driveway, both of which I constantly get compliments. I am glad to have found them!"

Sump Pump Installation FAQs, answered by experts

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.

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Inspect the pump annually, test the float switch, and clean the discharge line to ensure efficient operation.

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.
