"EXCELLENT CUSTOMER SERVICE Eddie visited our house the very day we called about our water heater. He came out, inspected the very tough location where the water heater is located and delivered an estimate with 3 options on the spot. We decided which direction to go and let Eddie know at which time he promptly scheduled our installation. On the day of install he arrived when he said he would, put down every type of floor protection you can imagine and proceeded the very difficult task of manipulating a 50 gallon water heater out of a small closet 10 feet up in the air. He worked with his partner to remove the old one, replumbed and installed the new one, again in a very tight space. Eddie ran all new venting to the outside, added electronic monitoring, and crawled under the house several times to make certain the drains were all functioning properly. We could not ask for better service and the attention to detail was amazing. This is our second experience with Excalibur Plumbing and they have both been wonderful experiences. Great customer service!!!!"

"I purchased a home in Cedar Park and needed a new water heater and other small plumbing repairs done. I saw Daniel's Plumbing advertisement on HomeAdvisor, so I decided to call him. I'm so glad I did! Daniel is very knowledgeable, professional, and a genuinely nice guy. His work is A+ and the price for the work done is very fair. I highly recommend Daniel's Plumbing, LLC for all your plumbing needs!"

"Although my malfunctioning pond pump wasnt an emergent issue, nevertheless they arrived within a few hours of my request and very quickly identified the problem and fixed it. I'm very pleased with the service. I asked Alex Castillo, the plumber for his card so I could have it for future plumbing issues."

"We have a water system on our place for cleaning and treating our water since we have wells. We have a water clarification system which we bought from them and they come out every year and do maintenance on it. It is more than just a softener, it's a clarification system as well, it crops out solids and everything. They've got a service tech that's really knowledgeable and knows his business. Their maintenance costs and service calls are not inexpensive but they are no different from anybody else. When they came to install the new part, it took about 20 or 30 minutes."

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.
