"Mike is awesome! We hired him to install a new water heater to fix an issue we were having with our plumbing, and when the new installation didn't fix the original issue, he made it a priority to address is quickly without additional payment. I think that's fantastic example of great customer service, and will be hiring Mike for any plumbing needs in the future."

"When I needed a major plumbing job I went to Green Planet Plumbing. I found their very impressive ad on the internet, and called for an estimate. Tyler Brown the owner came out and went over the job explaining what they would need to do, the time it would take, and the total cost. I was very impressed with the professional and friendly meeting with Tyler and decided to schedule the job. The day we set up Justin and Mike showed up introduced themselves and went to work. The first day they dug the trench to install a new waterline from the street to the house. The trench was about 40 feet long of very hard digging in rocky ground, and they to my amazement completed it that day. They laid the new pipe the next day, called for the city inspector to come out, and finished the job the next day. My wife and I were very impressed with Justin and Mike and enjoyed talking and spending time with them. I would not hesitate to call Green Planet for my next plumbing job, and will recommend them whenever I can. John Held"

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