"Kurt provided a quote very quickly. He was able to replace our water heater just as quickly and professionally. I highly recommend KLM Plumbing. Kurt exceeded our expectations and I will definitely be using him again soon to replace our water softener. Thanks Kurt."

"Very quick response to receive a quote. They arrived on time and did awesome work! They left me with a new tub, surround and fixtures and cleaned up all the mess. New tub looks great! I would definitely hire again. Thank You!"

"Difficult to review because the first person did not even fix toilet correctly, but the company did instantly return my call just by seeing my phone number on the caller ID, the second person was completely competent, professional, and courteous."

"The 2 workers were on time and performed the required work to install and remove the old water heater. They seemed in a big hurry ti finish and did not ( in my opinion) check the gas lines. 2 days after the installation there were 2 gas leaks and I had to call MGE to fix."

"I called at 10am, the owner of the company arrived shortly after 11 and was done by noon! I could not be happier. He explained the typical cause of kitchen blockages (dying garbage disposals), and scheduled me for a replacement 4 days later. When I suggested going with a more expensive/ powerful model, he declined the opportunity to upsell. He also took time to clean up the dirty water splashes under the sink, even when I told him not to bother. Also, my dogs liked him."

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

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.
