"I have what turned out to be a 30 year old water heater replaced by this great company and they did it the same day of the quote. The installer had the water heater I wanted on the truck and did an excellent job of putting in the new unit, cleaning up and even replacing copper flex tubing and installing a new overflow pipe out of copper as well, no additional cost. This company specializes in water heaters and couldn't do any additional work on supply lines and they clearly state that on their website. I didn't need that type of additional work."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"We noticed black particles/materials on top of our water heater. Our thinking was that the particles were coming out of the top of the water heater, where there is an opening that was just below the venting pipe that leads to the roof. I called Better Water Heaters and Frans (owner?) answered. I did not realize that he was in his truck on the way to another job. I described what we saw and did not think it was coming from the water heater. He suggested that I sent him the pictures that we taken and forwarded to him. Shortly thereafter, he called back and reconfirmed to me that he did not think the particles/black materials were coming from the water heater and that it is more likely, coming from the roof by way of the vent pipe. Frans responded fairly quickly and did not charge me for his professional assessment of the problem. As a result, I will call Better Heater Services in the future whenever servicing is required."

"Gustavo from Escamilla plumbing is a pro thru and thru. I gave him a tough job that I wanted to tackle but didn't have the necessary tools or time to tackle. I had him relocate the water heater lines and install a tankless water heater, remove steel pipes and redo drain lines. The kicker for the water lines was access next to a furnace and new gas lines that needed to be run due to insufficient gas supply. During the project we found micky mouse water line taps that needed to be removed and the house water shutoff valve that failed to closed completely. Lots of unexpected work but he gave decent quotes to complete the job. He is quick, doesn't cut corners, and gets the job done. I wholeheartedly recommend him for project a homeowner wouldn't touch or doesn't have time to do."

"The cost to replace three natural gas wall heater was slightly less than Gree mini-splits heater cooler. The installers were courteous and professional. Delayed several days as the equipment haven’t arrived yet. Job cost as agreed, but took half day longer due to the complexity of installation. Results are excellent. The mini-split units works as specified. Will use Albert Nahman heating plumbing again in the future."

"The complete process from the quote, to scheduling, to the installation of the tankless water heater was excellent. It only took one week from quoting through the completion of the job. The installation was completed in one day. The team was cordial and professional. Furthermore, the price was competitive. I would strongly recommend Super Brothers for your plumbing jobs."

"Replaced a filing water heater. The work was excellent. My water heater was basically blocked in by the incoming water and gas pipes, but the two-person team managed to remove the old heater, replace pipes as necessary, and get everything working again. Gave up-front pricing including permit inspection. Super professional crew."

FAQs for water heater repair or service projects in Union City, CA

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.
