"Called Excaliber first thing in the morning with no hot water and homeowners were remote. The response was that a plumber (Eddie Guerrero) was in the area and would come by in the morning for an estimate. It was discovered that the water heater needed replacement and the system brought up to code. Mr. Guerrero took care of water leakage and quickly gave an estimate, explaining the options fully. Once the estimate was received via text and phone calls, he came back a few hours later to make the install. He was efficient and thorough and communicated great about the install throughout. By 6 pm that evening, the heater was installed and hot water available. Excellent service was provided."

"I had a waterline added in the kitchen. They were a little expensive but they were timely and had great customer service. The plumber had to come back because the line was leaking but they sent someone to fix it the next business day. I would have given them a higher quality rating but they didn't turn the water heater back on after they finished the work."

"Installation took place 14 days after I had accepted the bid, which was contingent of them getting my broken one repaired the next day free of charge, Which they did. I would have rated them 4.5 stars if possible,"

"So this is probably the best plumber I have ever dealt with in my 12 years of home ownership so far. First of all - this review is not only about Mr. Rooter in general, but specifically about the plumber I was lucky enough to use - Jason Henderson. The guy is a total BOSS! The work we had done was first of all to convert my electric cooktop to a gas top, and secondly, replace my water heater. Jason can out pretty quickly, got everything hooked up for the gas line and then when the inspector came out with his notes, Jason updated the little things here and there to keep it moving. The water heater was a whole other animal. The old water heater was 27 years old, so WAY out of code. Jason spent a full day removing the old one and getting everything up to snuff. He also went the extra mile of doing a final pressure test on the gas lines after everything to make sure that when the inspector came out we KNOW we will pass. There are so many other little things he kept doing throughout the ay that showed that he truly cares about his customers. It may not be much if I listed them, but to me and my family it was these extra little things that made a whole world of difference. I would definitely recommend Mr. Rooter to anyone as their prices and timing was top notch, but, more specifically, if you can get Jason Henderson on your job - DO IT! You will NOT be let down!"

"Justine from Prostar was very knowledgeable and professional. She gave us great price options and followed up after the installation to be sure we were happy. They were on time and did a great job! The technician thoroughly explained what they were doing and how long it would take. We had several quotes/options, but Prostar Water definitely provided the best product and service for the money!"

"I am a general contractor. I have used many plumbers/ac companies in the past. I started using this companies services about 5 yrs ago. Most of my projects are in residential remodels. Although I also deal a lot with restaurants. I wish I would have known about this company earlier. Steven not only knows how to perform, but his knowledge about what is right and wrong sets him apart. I would not hesitate to refer him to any person or contractor that asked me. I continue to use his services. And my remodels show his excellent workmanship."

FAQs for water heater repair or service projects in San Marcos, TX

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.
