"In general J&S Plumbing is very responsive, they went out of their way to install a new water heater for us, in a tight space, within just a couple days of my first call. As for plumbing services, they mentioned that they do not charge extra for work in the evenings or on weekends, which many other companies do. The first power-vented water heater they put in had an issue with condensation drip-back, which caused the burner to have intermittent problems keeping the pilot light going. J&S was very professional and responsive to the problem. A month after the initial install, they ended up replacing with another brand new water heater, quickly and at no cost to us."

"Tech performed service per protocols. He informed me that the water line to the attached humidifier was brittle and needed to be replaced. This was an expensive repair but I was offered a discount. Per their points inspection, the Tech verified that there was no gas leak from my water heater. The thermostat was not inspected since it is functioning and we are observing COVID recommendations. I was given a five-hour window for the Tech to arrive. This is the longest time frame ever. I assume that the extra COVID procedures are the reason. The Tech was professional and respectful of home COVID measures."

"I called Top Tec Oct 4 to check my existing water heater. Steve came out and looked it over and gave me the bad news. My 9 year old water heater was shot. The next day, Steve removed my old water heater and installed a new Rheem water heater. I could not be more pleased with how quickly the work was completed and with Steve’s expertise!"

"I was very pleased with all the work Joe did at my Mom's house and mine in Cary. At my Mom's he put in a new utility sink and repaired it and also repaired a significant leak downline from a toilet. When I saw the quality of his work I hired him to work at my house. There he removed and replaced a hot water heater and repaired a big leak in my utility sink and replaced the faucet. With the water heater he had to remove the black pipe to remove the heater then repipe after. After he was done both houses were cleaner in the areas he worked . I would hire him again if I need any plumbing done in the future."

"I'm gradually switching from gas to a mostly electricity-powered home. C.A.B. didn't try to talk me into go with the same old fossil fuel water heater. Other plumbers wanted to take the course of least resistance and just install another gas unit. C.A.B. had the expertise and initiative to take on this complicated, future-looking project. We never run out of hot water!"

FAQs for water heater repair or service projects in Libertyville, IL

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.
