"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."

"Leon Plumbing was able to repair our tankless water heater, where two other plumbing companies couldn't. Sev was awesome about pinpointing the problem and explaining in detail the solution. He even followed up a few days later to check in."

"Victor from L.A. Plumbing Pros came out Jan. 28 to start my water heater. He was here within a half hour of his call. He gave me a ball park price over the phone for doing the job but told me when he got here he did not realize I was within a couple of blocks of the Altadena fire. He said there is no charge. He was very gracious and kind and I am so grateful to him. He got the water heater to work in just a couple of minutes. Thanks again Victor."

"We called John’s Plumbing and Drain Service to replace our old water heater and pressure regulator. John came out, gave us a quote. Since we were doing more than one item he offered us a package deal. Due to high pressure our water heater was busted. After replacing regulator and installing a new water heater the issue was sold. John did the job with reasonable price. He is very knowledgeable. I will highly recommend John’s Plumbing Company."

"The team of this company which included Samuel, Agapito and Sergio did a wonderful job. The job was really hard. It included removing an old water heater from a small cabinet under the stairs and placing a new heater which was taller. I am very grateful for their job."

FAQs for water heater repair or service projects in South Pasadena, 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.
