"Price is negotiable if you have another estimate to compare to. Heaton handled the pickup of the water heater from Home Depot. The job was bid, sold, and completed on the same day. The installers were first-rate..."

"Iâ ve used Joe at Pipers Plumbing for a previous issue with my tankless hot water system. Joe brought my system up to code and added the items needed to do so. We are finishing up a complete remodel of our 2nd floor (which the contractor used his own plumber) we ran into what was originally thought to be a major problem. Our sink, toilet shower and one of the outside hoses ran nothing but HOT water! After spending 30 mins or so trying to figure things out we started discussing where we were going to have to cut in the ceiling of first floor to get access to where we thought the water lines were crossed. (I had many pics and videos of remodel) Joe thought of something. 10 mins later everything was fine and disaster was avoided. The stem in the shower valve wasnâ t installed by previous plumber and it was allowing hot water to feed into the lines. Saved hundreds if not thousands of dollars in work. Then, when I asked what I owed him he said nothing.. $0.. Told me he was glad to help and glad that we were able to fix the issue. When I tried to pay him $100 he continued to turn down the money and told me to consider it my â Veteran Discount â and thanked me for my service in the Marine Corps! Awesome company!"

"Did a great job with a challenging situation. Chris spent time figuring out several options for me. They went ahead and relocated the new tank water heater. It was a long job but it went very well. Chris and Evan were great, explained everything to me and cleared up afterwards. I would highly recommend this company. They pulled the required permit and the inspector said they’d done a good job. I will use them for my servicing now."

"I originally called Nick's Plumbing to fix a kitchen faucet that I could not fix myself. David had it repaired in about 5 minutes. I was embarrassed that I couldn't figure it out myself. I figured that while he was there, I'd ask some questions about our hot water supply. He checked our water heater to find it was 12 years old. It had never been serviced. The 12 years of sediment build up explained poor hot water supply. I asked about replacing with another tank and the cost for a tankless system. It was about 2½ times more expensive to put in a tankless system. The 40 gallon water heater was in our attic. The thought of a leak in tank, and the possibility of 40 gallons drenching the house - and the continued water supply trying to fill the leaking tank - was the 1st thought that came to mind. I'm looking towards retirement soon with no regular paycheck to replace a water heater. I asked myself "if I'm going to replace a water heater in the next 2 to 5 years, isn't NOW the time to do it?" We are planning to retire in our current home. The tankless system seemed to make sense for us now and into the next 10 to 20 years. I plan to have THIS hot water system regularly serviced so that we get more than 12 years use out of it. David and Jorge got all the parts and materials to replace the old water heater with the new tankless system. This included replacing the roof vent - tankless requires something different than a tank. I was home when they initially arrived and when we negotiated the replacement. I had to leave for work but my wife was there while they worked. She said they departed about 4 pm so it was an all - day job. Nobody replaces their water heater on a whim. Something bad has to happen - like a leak or no hot water. I got lucky. I replaced my hot water heater by talking to an experienced plumber about annoying issues. I got it replaced before something bad happening. Thanks David, Jorge, and the folks at Nick's."

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