"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!"

Within two minutes Mr. Rooter call and Frank showed up an hour later he was very personable and told me he could replace it right away three hours later the job was done and I have my basement bathroom and laundry room up and running the price was well within what I expected and I should mention that this was on a Sunday. I would definitely recommend this company."

Sump Pump Installation FAQs, answered by experts

To test for toilet leaks, use water coloring in the water tank and see if the water slips into the bowl from the tank. This test will indicate if there’s a problem with the flapper or refill tube. You can also put water coloring in the bowl of the toilet to see if there is a leak there. If there is, you should see the colored water on the outside of the toilet bowl or on the floor. 

Costs range from $300 to $1,200, depending on the pump type, issue, and installation complexity.

DIY is possible for simple repairs. Professional services ensure proper diagnostics and long-term reliability.

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.

If you’re wondering if your home even needs a sump pump, consider whether you’ve struggled with flooding issues in the past. If your house is in a flood-prone area, your yard has poor drainage, or you’ve dealt with any other water problems, then it’s likely well worth it to replace your old sump pump with a new one.
