"I had a 75 gallon hot water heater that failed during the middle of the night. I called Water Heaters Now at 7:00am and they had Bruce at my house at 11:30am. New hot water heater installed by 1:30pm. Bruce and everyone at Water Heaters Now did a great job from start to finish."

"After various and outrageous quotes from local plumbing companies, I hired Yuriy and his crew to install a new Rinnai tankless water heating system at hour house. The project included the install of the new unit at a different location in the basement and the conversion/hookup to the main natural gas pipe which was feeding our furnace. We previously had an electric water heating tank system that lasted 23 years. The removal of the old tank was included as well. He also did about 12 feet of old galvanized pipe replacement with copper piping and various shut off valves, wall anchors and a hookup to an existing humidifier. The final price was fair and the work was done beautifully and on time. Any issues during the project (minor stuff) were tackled quickly and efficiently. It was really a very nice experience. Yuriy and his crew were very knowledgeable and highly professional! in the end, we were very happy with the result and we're enjoying our on-demand, very efficient"

"The plumber was on time for this job and explained what needed to be done. He gave me several options about dealing with the leaky valve because he was able to tighten it so it wouldn't leak; however it was old and would likely need to be replaced sooner rather than later. The whole thing took about 45 minutes. I have also used these plumbers for a new water heater, replacing a toilet, and twice for repairs of leaking situations."

"Dave did a great job! I'm glad I picked him over the other 2 quotes I got to replace my water heater and a noisy, slow-flowing kitchen faucet. A true professional. Good and reasonable pricing. On time and reliable. Very nice human being. Will be calling him again should any plumbing troubles arise."

"Harrison replaced 2 water heaters for us, and 1 toilet. Both jobs were done professionally and the price was as quoted, very fair compared to many more expensive options. He had time open on his schedule to come next-day. He's now my go-to guy and I'd highly recommend him!"

FAQs for water heater repair or service projects in Cottage Grove, MN

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.
