"It went very well. Before my service guy Eric showed up, the company sent me his photo, advised they were following safe Covid practices and gave me an ETA for his arrival. Eric was very professional and he assessed that I needed a new thermocouple. Eric installed the thermocouple and had the furnace running again promptly. He also advised me that Arctic Air had a plumbing division when I was asking about replacing the hot water heater. He took the time to call the office about the cost of replacing my hot water heater and gave me a quote good for 6 months. Eric was very knowledgeable, welcomed my questions and he really impressed me. I had been looking for a trustworthy service and I feel I have found that in Arctic Air. I highly recommend the service."

"Had my aging water heater replaced in addition to some updating to the attachments. Technicians, Jack and Paul, did a great job on the installation. We’ll see how the new water heater runs, but they were knowledgeable and professional in their service."

"We were so relieved that the pro called right away and was able to fit the repair into our work schedule by coming early on Saturday morning. He was professional, neat and affordable. We are now planning other plumbing projects in our home with this pro. Thanks, Leacy Plumming and Heating!"

"After fruitless attempts to even get a plumber to return our calls, we found Easy Flow through Angie's List. Mr. Robert Magliulo responded the same day! He was cheerful, friendly, and eager to be friendly and accommodating. He came the next day to evaluate the problem and to provide a written and reasonable estimate. Upon tackling the job, Robert found it to be more ticklish than originally thought. He was absolutely correct. It involved a shopping trip for additional supplies so that the finished job wasn't jury rigged. Despite the extra time and trouble, the final price did not change from Mr. Magliulo's estimate. The finished job proved to be a safe and professional solution to a serious problem we hadn't even been aware of. Mr. Magliulo made certain that we knew we could call on him if there was any problem. There hasn't been. We were delighted and grateful. I would recommend Easy Flow to anyone requiring plumbing services!"

"This review is solely about the installation portion of the Puronics Water Treatment System since it was just installed today. The install team arrived on time, ready to go to work. The location of my main water line was tricky to get to, but they found a great solution to tap into the line via a drop-ceiling access point. They located the Hydronex Water Conditioning Cylinder and Salt Backflush Container exactly where I wanted it. Their work was clean, tight, and very professional. The RO system was backordered, so they explained that they will return within the week to install that portion of the project. They prepped for the RO install by drilling and installing the faucet in my granite countertop. After the install, they explained the whole system to my wife and I and we were up and running with conditioned water. I can't say enough about my experience with Chuck on the initial phone call, Miles who provided the water testing and sold me the system, and Ryan who installed the system. So far, I can't envision any issues that might arise with Orbit Water Solutions since they have provided outstanding service to this point!"

FAQs for water heater repair or service projects in Flemington, NJ

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
