"Jacob thoroughly looked over everything; water lines, gas line, igniter, gas valve, connections, etc.. He took the time to make sure everything was working properly and even educated me on a few things I didn't know."

"I cannot say enough good about this company. This is our second service with this company in the past 2 months. Reasonable prices. We had Jason Becker replace a faucet and shut off valves in our kitchen. He was very personable , quick and efficient. We would not hesitate to call Anton for future work. If it would be a plumbing project, we would request Jason B. We are very glad we found your company and you have very good employees. "

"Called Sam on Friday for quote for water heater replacement. Said he could do Monday afternoon or Tuesday morning. Received call Monday morning to see if he could come on over to do replacement, what a pleasant surprise! Sam arrived shortly after with water heater we discussed & all supplies needed , no running around to pickup stuff. Job completed in timely manner. Old unit hauled off and job site all cleaned. That’s a big deal to me. Will not hesitate to recommend Liberty to friends & relatives ! Thanks Sam , Dave & Roxanne"

FAQs for water heater repair or service projects in Saint-Louis, 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.
