"I called Tap Heating and Cooling early Sunday afternoon.  John was at the house within an hour.  He explained to me what the problem was and how it could be fixed.  He left to go get parts and was back within the hour like he said.  He assured me he wasn't leaving until I had heat.  When he left I had heat.  Thank you John.  In the future Tap has won my business.  Nothing but professionalism, honesty, and courteousness was shown.  Great customer service.  You will be hearing from me in the near future.

"Gracious, friendly and professional. Responsive- Brian was able to come the same day for the service call and fix our heating system. As we hadn't services the other heating system in our house, I asked them and they serviced that too. Would hire again. Highly recommend."

"Tim gave us an honest evaluation of our existing water heater and options for repair or replacement. We decided to replace the water heater and Tri-State scheduled the next day. Installation was professional and l think Tim is the kind of craftsman you want representing your organization. The fact that you install the Rheem brand helped close the deal."

"We had a very good experience with our Bathroom Remodel. Basically, the bathroom was gutted. Dylan was the representative that helped us through the design process. He brought all samples to our home to make choices. He was patient, knowledgeable, and overall, very pleasant to work with. Ben and Kellan performed the work on the project. They were very professional, and extremely hard working! They literally took lunch breaks and other than that worked the entire day without breaking. They were quiet as can be, they didn't have any music playing or even receive private phone calls. They cleaned up after themselves each evening before they left. Extremely pleasant to have in our home. They kept us informed along the way and paid attention to detail. We couldn't be happier with the end results, job well done. I would definitely recommend them or use them again. Steve & Debbie K."

FAQs for water heater repair or service projects in Washington, MO

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.
