"I’ve used Anthony Heating & Plumbing for close to 8 years. They’ve replaced heating/A/C and water heater. They also have done some plumbing, fixed a sump pump issue, installed new PVC pipes for better flow and do annual general maintenance on my A/C and heater. They are punctual, friendly and clean. A few of my neighbors began using them."

"I noticed that there was no hot water coming out of the sink when I turned on the spigot, only cold. I went to the basement and saw that there was water leaking from the top of the hot water tank and spilling down the side onto the floor. This was a weekend. I called KC Plumbing and he came out to inspect. Thankfully, he found out that the tank was still under warranty with the manufacturer. Since we still had water (cold) it wasn't an extreme emergency so he was able to fit us into his schedule on the the upcoming Tuesday. The work was done efficiently, economically and completed in 1 day which was great. This is the 2nd time we have used this company. We are quite pleased with the experiences we have had with KC Plumbing. The owner, L.J., has serviced us very well and we will use him again when we have any other plumbing issues."

"After our water heater was spraying water into the basement. Erick from Arcadia arrived quickly, gave us a fair estimate and was at work that same day with a friendly crew. While they were working they found some corroded pipes that were in bed shape and they added that work on to what they were doing that day, and had everything finished by midafternoon. I was pleased with the work, pleased with the price, and pleased with the friendly service. Erick is a super nice guy! And his team was great. They are a contractor service so they do all types of jobs. I’ll definitely be using them again!"

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