"The repairmen was very professional and experience in his craft, I was shocked at how fast they responded to my request. It is a known fact that electricians,plumbers, carpenters and etc. are very expensive, but three or four hundred dollars to replace just a water faucet is entirely to much. As stated previously, I hired them to replace my air conditioner and they did a masterful job."

"Revilla’s plumbing did a great job with locating the leak in my bathroom, repairing the leak and coordinating the remodel. Tim is very well connected and we were able to treat the affected area to prevent mold through a relationship vendor he trusts and does business with on a regular basis. Since my bathroom remodel, he has replaced my water heater, a water heater for my parents and some faucet replacements around my house. I trust Revilla’s plumbing will do the job right at a fair cost."

"I had a great experience with the team who first came out and identified the reason I had no hot water to the replacement of the water softener which was the problem. I decided to replace the water heater as well because of its age."

"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!"

"Contacted after foundation repair. Inspection found sewer line break under slab, tested and quoted price. Work began following week and continued through the following week due to weather (rain). Project completed, though I'm still awaiting final receipt still after work completion I have their initial receipt and work was done to satisfaction. Seem like good company just a bit slow on receipts. Other than that I'd recommend and would use again."

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