"We had a problem with our water heater only heating half the tank. I called Precision Today and they could not have been nicer. This includes from the time I called, speaking to the woman on the phone. They sent someone out the same day. TJ was incredibly knowledgeable and professional. Turns out we needed a new water heater. He got the new one and installed it same day. This guy knows his business!! I canâ t say enough about the honest, professional work we received. Weâ ve used other companies that didnâ t come close to Precision. So grateful, thank you!"

"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!

"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."

"Patrick, the owner made the service call to my house in about 1/2 hour. I was alone, babysitting for my two grandchildren and very worried. I explained my problem, he told me what to look for (a water shut off valve) and asked if I could turn the water off. I told him I would try. I was frantic because with the babies, then not finding any shut off valve, water coming up from the floor, and clearing way for what I thought would be a wall tear down - Patrick and his "manager" (?) arrived. (Mind you, my family also came to help, but did not locate the shut off valve). The water pipe happened to run under my bedroom floor! Needless to say, WITHIN MINUTES the rushing water stopped. I still have water for daily household use as the problem was a broken pipe to the exterior spigot.  Patrick was soaked, yet took the time to explain to me why exactly this had happened. He encouraged me to wait until the Spring when the weather is warmer to make any changes and repairs. Patrick is professional, knowledgeable, and quite a gentleman, (despite being waterlogged) and I felt that he gave me all options for this future repair.

"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 Oak Park, 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.
