"The price is comparable to others. At 72 everything seems outrageously expensive. Steven is very capable, considerate and professional. Was so relieved he got it cleared. It was at the end of his 25â auger so Iâ m sooo glad I didnâ t try to do it myself. Thanks Steven!"

"Fixed the hose bib but not how the faucet was sitting on the siding. It was loose and had a gap between the siding and faucet. $500 for a small gasket fix in the faucet is crazy. Lesson learned. "

"Good price, work seems well done. Only 4 stars because we had settled on a particular heater, but he messed up and got a different heater (less efficient). He did call and admit that and gave me option to reschedule, he could order the other one. "

"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.
