"Tom called promptly after I posted the project at 7PM Monday night. By Tuesday at 3PM I had a new water heater installed and working, and at a good price. Very professional. They arrived early and there were no (bad) surprises."

"I was thoroughly pleased with the installation of my new kitchen faucet. What I liked is that they went above and beyond. There were other things in the house that needed attention and Kyle changed did a "wellness" check around the house, the bathrooms and found that the faucet to the outside of the house needed updating. I wills say that their price was a little high but for my peace of mind, it was worth it. Within 5 days of my work being done, I recommended them to a co-worker who needed a hot water heater repaired and they are satisfied with that work too. Yes, I will call on InstaPlumbing again."

"Thank you HomeAdvisor! I spoke with them late on a Saturday and by Monday afternoon my new hot water heater was installed. They shopped around to get me the best price on the equipment I needed and were so kind to keep me informed as to their arrival time. They did a fantastic job getting out the old and installing the new, I am super happy!!! I would definitely recommend them! Thank you Mike and Todd!!!"

FAQs for water heater repair or service projects in Waterbury, CT

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.
