"Drain was initially cleared using a drain augur, but inspection via camera revealed that additional cleaning was needed. A followup visit happened about a week later to perform a hydro-jet flush and the video inspected now showed a very clean drain pipe. The technician was very professional and explained the steps he was following and what he observed. I would recommend this company for this kind of drain service."

"The service team kept in touch regarding arrival time so I knew what to expect. The technician Jonathan worked quickly and efficiently. He had a water heater on the truck and was able to complete the work same day, unlike 2 other companies I got quotes from. While I was shocked at what water heaters cost these days, High 5's price was very competitive with the other bids."

"Excellent...we had some additional issues related to water pressure regulator, piping, etc. The situation happened on the weekend and we had hot water running by Monday afternoon.

FAQs for water heater repair or service projects in Longmont, CO

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.
