"I was looking to possibly replace my water heater. It is old but functions fine and I have no problems. After talking with Water Heater Now rep he told me that since I have a well it might be better to leave my current functioning water heater. He explained that while they offer excellent warranty I am better off with an older model if I don't have any problems. While I decided I will keep my water heater until it shows a problem I will definitely call Water Heater Now when I need a new water heater."

"Installation of a new natural gas water heater was done in about 3 hours. He had to come up with a way to have the water heater raised as it sits on a drain pad and the flat surface of the heater bottom would have closed off the drain. The old heater has legs. He used PVC pipe pieces to elevate this new heater. He replaced the gas shutoff valve and the water shutoff valve. The old ones were over 36 years old."

"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."

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.
