"SuperHandyMan was very responsive to my needs. Our 22year old water heater needed to be replaced. Once a scheduled time was agreed, the service was fast and efficient. Of all the companies contacted, the price was the best. 5 stars!!!"

"I want to thank Hosack Plumbing, and Kent, for getting my situation cleaned up quickly and professionally. My water heater install is perfect, my water pressure spot on thanks to the new PRV, and is ready for inspection. Kent was thorough, professional, and very clean. He noticed my mask when I answered the door and wore a kn95 mask the whole time. The life coaching advice was an added bonus. Kent's work was great and I'm very pleased with the service provided."

"Sam Marsala was very good at diagnosing my furnace trouble, the fix was simple to my relief. My water heater was on its last legs. Sam diagnosed the trouble and we had Sam install a new Raheem water heater. He was very quick to respond to my needs and explained very clearly the trouble found. Installation was really done neatly and he left the work area very clean. I am more then satisfied with the work, product and technician. Well done."

"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"I purchased an electric tankless and pre-filter/softener directly from the manufacturer and started hunting for a plumber to install it. Now most all plumbers recommended against a tankless hot water heater, and Maplewood wasn't really any different in this regard. BUT, they listened to us, didn't treat us like idiots, and obliged us in our foolishness and they were really awesome. They did the job quickly and without a mess. Also, WE LOVE OUR NEW TANKLESS HOT WATER HEATER! I looked at our electric bill after 2 months (March-April) of using our Stiebel-Eltron E-tankless whole-house water heater unit, and the kW usage actually DECREASED from one year ago for those same two months. That’s right, there was no increase in our electric bill. As expected, our gas usage decreased. My wife was very worried because she often ended up talking to the plumber issuing the dire warnings and predictions about our silly misguided endeavor to get a tankless unit. Now, she couldn’t be happier. Tandem back-to-back showers all day long, if we wanted. Never ending hot water! Thank you Maplewood Plumbing for helping us!"

"Total Comfort did an excellent job. I recommend them. Also I have used Home Advisor for other repair contacts and have been happy...but am not sure I would use them again for one reason, which is that Sears hvac representatives called 15 plus times daily after I declined to use them because of previous issues with them. They will no doubt cause them to lose customers."

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.
