"Veteran-owned business. Honest, reputable and on time for the appointment. Ross and David spent all afternoon clearing out two clogged drain spouts and replaced/repaired a badly cracked PVC pipe after hydro jetting them. They inserted a snake with a camera and showed me the problem. They also provided a veteranâ  s discount! Thank You. Brad Pesek"

"Jordan came out and was very friendly and knowledgeable about my leaky waterheater. He took time to explain why it was leaking and advised me on how to keep the new one maintained. Jordan was very cautious and made sure his mask was on. I really appreciated that! He did an excellent job in installing a new one and made sure things were cleaned up when done. I would refer About Plumbing to anyone and will use them again when needed."

"Everything went well and smooth with their help. I got the proposal with all details at the same day when they came to do the estimate. Our old furnace was built on 1971, and it was in a closet next to the water heater tank. When one other company came to estimate, they wanted to cut a furnace size hole on the wall facing the hallway to fit the machine and we have to find a constructor or handy man to finish, like to build a door or make it look good, but G&S figured out an easy way, which is to turn the machine toward another direction and eventually only cut a vent on the wall. It took two days for all the installation, and they cleaned up when they left and everything looked clean and nice. They also listened to customers. We didn't want the heat pump to be right next to the stairs of our deck, so they chose a spot which was few feet away from the closest spot without any question. We appreciate for that, since the wind blows out from heat pump is kind of strong, and we feel comfortable with where it is at now. One thing I really like is they were on time, and they called around 30 minutes ahead before them showed up. They also take care all the paperwork for the PUD rebate, Costco 10% shop card, and city permits, and all we do is waiting their call to arrange the time."

FAQs for water heater repair or service projects in Mount Vernon, 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.
