"I’ve used Mike twice now, last time for a sump pump replacement and water heater flush. Did great work and takes the time to explain what is going on. I don’t feel like he’s trying to upsell services to me like some other plumbers. Highly recommend."

"Horatio and his team took my "sump pump turns on every minute, don't know where all this water is coming from" issue to their heart which is heartwarming to experience. They diagnosed the problem by spending like 4 hours at my place and when we could not figure out the exact cause, they did help narrow it down to being either a broken intake pipe or high water table. They also put a temporary reroute for ground water to rule out any issues with the sewer line which is the case sometimes. They replaced one of my broken sump pump too for a reasonable price."
Pipe was completely packed! Drain cleaning was not going to do the  job here!

"On November 15th Chicago was hit with some extreme wind gusts that caused my water heater pilot light to extinguish. I thought this was a simple reset, but the problem was more complicated. I learned the electrode was defective. Had I undertaken this project as a DIY, I would have spent more time than I would have cared to try to figure out why I could not get a flame for my water heater. I was smart to call Four Seasons. My technician figured out the problem quickly. There are times when calling a professional makes sense. I am not an expert on water heaters outside of knowing how to turn it on, clean it periodically, and knowing when I need a new one. Thank you Four Seasons for responding quickly and bringing me hot water."

"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 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."

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