"I coordinated the work with Mr. Rooter's home office. Unfortunately, they didn't relay to the technician that he needed certain materials to get the job done. This caused about a 60 minutes of extra time for the technician to search around for the part and then go pick it up. Other than that, the water heater gas control valve was successfully installed and I've got hot water again."

"Made sure to provide honest input and save me money by not taking advantage of lack of knowledge as a new homeowner. Juan came out and was extremely polite, professional, mindful of our home with protective covering on his shoes and assessing items quickly and efficiently. Would highly recommend recommend this company and I rarely write reviews. Sometimes your experience is so good you have to share. "

"Contacted Four Seasons to rod my sewer drain. They came out and stated that they would need to come back the next day with the rod and camera water jet to see what is clogging the line. In order to lock in the amount of almost $1500 and the time of 8am-1pm, I will need to make a down payment of half. I did half. The next day a guy from the company came with only the rod.and when I questioned him about the camera, he ignored me and continued his conversations via phone with others. Later he tells me after I asked again about the camera that I owed the other half $750. I did not pay and informed him that I didn?t get the services that I had made a deposit for in the beginning. He then started that the guys are busy and will be out on Monday 1/12/2026. He stated he went 55ft with rodding. No one came on 1/12/2026. On 1/12/2026 and 1/13/2026 I spoke to 3 managers and a supervisor?Brian, Jenny, and another person who didn?t know Jenny or Bryan and I was told that the rodding was $740 and"

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