"I have called about ten company to give me quote. Some of them came to my house to inspect and give me their quote. Morse Plumbing LLC is the lowest. They did everything what I expect them to do. Before they filled up with water Luke(the owner of the company) he check all the bolts, nuts, couplings, and all brass fittings to make sure everythings are tight. Akso he uses spray bottle with water mixed with dish soap to check if natural gas is leaking. That tells me that this guys knows what they’re doing. Luke even help me to registered for my warranty. After the $50 I give them for tips still they are the lowest price…If you needs plumbing job, try Mores Plumbing LLC you will not get disappointed."

"I had an excellent experience with Jose Plumbing Excellence Northwest. They first helped me fix a leak, and later replaced my water heater when it went out. Both times, they were able to schedule me right away, which I really appreciated. The team was professional, efficient, and made sure everything was done correctly. Their customer service was great from start to finish, and they made the whole process smooth and stress-free. I highly recommend them for any plumbing needs!"

"Our water heater started leaking and the original installer advised we would need a “custom order” and a replacement part that wasn’t readily available. After research, we reached out to Washington Water Heaters for a second opinion. Steve was very knowledgeable and was able to scheduled us with a same-day appointment. Len identified the core issue, fixed the leak, and cleaned up all in 30 minutes. Stellar service , efficient, and very fair pricing. "

FAQs for water heater repair or service projects in Seattle, 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.
