"Our sixteen year old water heater was leaking gas. My husband called The Water Heater Company who quoted for exactly what repairs were needed. The telephone representative who helped us requested photos of the water heater. He could tell what items were needed to bring the new water heater up to code. We were very pleased that Tony, the water heater installer, was scheduled to come the next day! Tony was punctual, thorough and answered all the questions I had. He explained everything that was done and made suggestions for other improvements we might want to have done. Everyone was very professional and very honest from beginning to end. They also use the very best water heaters with great warranties. Much higher quality than you can get at Home Depot or Lowes. We are very excited to recommend Tony and The Water Heater Company!"

FAQs for water heater repair or service projects in Chatsworth, CA

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.
