"The company was professional and responsive from the consultation to the office staff to the various people who worked on our project. I had tried to contact about 10 companies to get our heater/ on demand hot water heater replaced. Addario's was the only one who responded immediately and was able to fit us into their schedule to get the work done. We had contact with at least 8 staff people in various capacities, and all were professional, polite and knowledgeable. We also appreciated the senior discount for our project and assistance with the MassSave rebate process.. It has been difficult for us to find service people since we move to Gloucester. We were surprised that the company services this area and we would definitely use them again for plumbing or electrical services."

"Justin was professional and knew exactly what I needed to fix my existing water heater without trying to upsell me on a much more expensive tankless water heater. He had the relief valve and expansion tank in his truck and was able to install everything without issue. I would recommend hiring them for your plumbing needs!"

"I had a great experience with this plumber! He arrived right on time and was very professional and friendly from the start. I had a leak in the plumbing in the wall between the bathroom and the bedroom and he took the time to explain exactly was going on. He even went under the house (in the cold and dark) to inspect the issue further and took pictures so I could clearly see the problem myself. He explained the repair in a way that was easy to understand and fixed the leak quickly ad professionally. I really appreciated his honestly, communication and the quality of his work. Everything is working perfectly now! I definitely would recommend him and would happily call and refer him if I ever need a plumber's help!!"

"Christian was very knowledgeable about our water heater and explained everything as he went along testing different issues that might be causing the problem. He was professional and gave me several helpful tips on upkeep of my Rinnai that 2 other companies that had serviced the unit over the years had not bothered to mention. i absolutely would recommend Walley to anyone needing HVAC work."

FAQs for water heater repair or service projects in Derry, NH

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.
