"My water heater has stopped working and water heaters in a hurry was able to come out same day, on a Saturday. Jeff was professional, knowledgeable and explained all of my options. He ended up replacing the water heater and upgrading my system. He was thorough and clearly wanted to make sure that the job was done right. I would definitely recommend this company for any issues with your water heater."

From this angle you can see how the previous installer used iron gas line for water (again will rust and clog)

"Crew members Trong Chau, Tan Pham did an excellent job for the installation - prompt, professional, and thorough. Staff Dante Zappala professionally measured and sized the system. Unique Indoor Comfort staff were very slow in providing warranty papers for the extended warranty of the Rheem Water Heater - it took a month to get the proper sticker to validate the warranty - and made it seem like a problem. We hope that they respect the warranties for the A/C and Furnace through Carrier."

"Our 10 year old water heater sprung a leak one morning and I discovered a mini flood in my basement. I called ValDel and had a tech, Tim, at my house an hour later. Tim was very nice and professional and had my new 50 gallon heater installed within two hours. He also put a ball valve onto the new heater as our old one did not have this (which forced me to turn off water to the whole house to stop the leaking; if this ever happens again now I can just turn the new valve off to shut off supply to just the heater). We also upgraded to a 6 year warranty on the new heater. We've used ValDel before and have been very happy with them."

"Bryan serviced our heater, he also told me about the condition of our heater. What it would take to repair it & that the age of the unit would make it too costly to repair. We appreciate your quality work & your advise, thank you."

"They are very professional and efficient. They respected my property and did a very good job installing quality water heater. Price charge is fair compared to others. Financing is great, too, with no finance charge if paid in 12 months. I'm very happy with the persons who did the work."

FAQs for water heater repair or service projects in King Of Prussia, PA

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.
