"I had tried to lite my Water Heater multiple times and it would not lite. I am a retired HVAC Technician myself and have lit many Water Heaters before. I thought there was certainly something wrong with it. The Technician from 100% Plumbing checked it out , lit it , and didn't charge me a dime. There's not a lot of Companies or People that honest anymore. I would recommend 100%Plumbing to Anyone looking for a Plumber."

"The gentleman did an okay job at flushing my water heater , however he spilled water in my attic which then leaked over my bathroom and tried to convince me it rained and my roof was leaking. At the end, he hired some guys to replace the ceiling in the bathroom at the company expense."

Usually, the two most important questions you want to be answered are? What?s wrong? ?And? How much is it going to cost? At Luke's Plumbing, we don?t have a problem giving you a price over the phone. Many Houston homeowners who call us are frustrated because they have called other Houston plumbing service companies and have gotten a run-around when it came to getting a price. It is sad to admit that our industry is plagued with plumbers who intentionally will not give you a price or even a ballpark estimate over the phone because they want to get in your home where they can pressure you face to face into spending more than you should. One of the highest numbers of complaints to consumer protection agency is for home improvement and service companies.. Plumbing license: MPL 37466. A/C license: TACLB 53102E. Call us today for all your plumbing needs!

"I checked PDI's reviews and they almost seemed too positive. After they took care of a water heater problem that an electrician failed to figure out, I now understand why their reviews were so high. They really exceeded my expectations."

"David Muna was very friendly, courteous, and above all, professional. He explained to me in detail what he was going to and why. Not once did I question his integrity nor his ability to repair my kitchen sink on time and at a reasonable cost. I highly recommend David and JD Precision Plumbing Services, and I would not hesitate to use them again."

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