"Ned from Mast Plumbing did an outstanding job installing my gas tankless water heater. He was professional, knowledgeable, and took care of everything from start to finish. He made sure the installation was done properly, explained everything clearly, and left everything clean and looking great. The pricing was also much better compared to the larger plumbing companies, which was a huge plus. It?s great to support a local company that provides excellent work without the inflated prices. I really appreciate the quality of work, attention to detail, and customer service. I highly recommend Ned and Mast Plumbing to anyone looking for a reliable plumber!"

"My water heater was leaking badly. They were there in 2 hours, and in less 3 hours later; we had a new water heater installed. Very professional and quick. Honestly it was a little more than another quote, it's a better water heater and I would have had to wait four days for an install. Very pleased. When its an emergency, you want fast quality service; which we received."

FAQs for water heater repair or service projects in Olympia, WA

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.
