"Technician was friendly and helpful; reviewed hot water heater and suggested that it may be covered under warranty (which it was); did the additional work of calling into the distributor with serial # of unit to verify unit was covered and saved me the cost of a new unit; would definitely hire again!"

"There's really not that much I can say. The two men who arrived both put booties on, which was nice. One of the men ran a test for chlorine (found some) and to determine if I had hard water (I did). Normally I wouldn't have allowed two workers, since I've been burned in the past by theft. It's a common strategy for one worker to turn the water off and while you are watching the man who is doing the inspection and repair work the other is looking for items to hock. But these two seemed honest enough. After all was said and done the disposer was beyond repair -- something had "snapped." The disposer was relatively new so I wasn't about to purchase a new one. The man said he had never seen a disposer vibrate that way, but I had researched it online and it's not too uncommon. ???"

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.
