"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."

"I contacted TYCO Plumbing with regards to an issue with our water heater. They were quick to respond back and got us on the schedule for the following day. Their technicians, Josh and Lance were responsive, on time and very professional. The work that they performed was high quality and they had the job completed within a couple of hours. I would absolutely recommend TYCO and plan on using them for all of my future plumbing needs."

FAQs for water heater repair or service projects in Boulder, 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.
