"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. "

FAQs for water heater repair or service projects in Lake Forest, 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.
