"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"Wes came out to look at a water heater issue my mom was having. He took the time to explain what the issue was, offered options, and ultimately replaced the water heater and some of the old piping around it that needed it. Never had a problem since. After that, we also hired Wes for other pipe replacement in the garage and in the laundry area. Again, haven’t had an issue since. He is a professional and I appreciate trusting that the job is done right and not being gauged for it. I would absolutely recommend Rapid Rescue Rooter & Plumbing."

"â I recently had the pleasure of working with Garrett from Walterâ s Plumbing on multiple occasions, and I must say, his service has been nothing short of exceptional. Garrett has a unique blend of professionalism and personability that makes every plumbing task seem effortless. When my kitchenâ s dish disposal unit malfunctioned, Garrett was quick to diagnose and fix the issue, showcasing his in-depth knowledge and expertise in plumbing systems. His work didnâ t just stop at repairs; he also expertly installed a new air vent for my dryer, ensuring everything was up to code and functioning efficiently. In addition to plumbing, Garrett proved his versatility by changing out the lights and fixing the fan in my office. These tasks, although not typical for a plumber, were handled with the same diligence and attention to detail as his primary trade. Most impressively, Garrett installed a new water meter for my sprinkler system. This task, essential for my lawn care, was completed with precision and understanding of my specific needs. Throughout the process, Garrett was patient, taking the time to explain each step and ensuring I was comfortable and informed. What truly sets Garrett apart is his trustworthiness. In every job he undertook, he demonstrated integrity and a strong work ethic, making sure that the work was not just completed, but done right. In conclusion, Garrett is an exemplary plumber who goes above and beyond. His helpfulness, diligence, understanding, patience, knowledge, and personable nature make him a standout professional. I highly recommend Garrett from Walterâ s Plumbing for any plumbing needs; heâ s truly a master of his craft.â"

"George was very knowledgeable and informative. He taught me what was going wrong and how to figure out the source of the issues. He helped me pick out a water heater that worked for my house and my budget. Furthermore, he really worked with me and gave me a very fair quote. When he came to replace my water heater, we had some other issues that helped us out with right then and there. Happy to be supporting a family-owned company."

FAQs for water heater repair or service projects in Azusa, CA

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.
