"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"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."

Customers say: Super punctual

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Excellent service! Pablo called immediately after I had submitted my HA inquiry, to see how he could assist with my project. He was able to come to my house same day; and even showed up to the appointment earlier than expected. He did the work efficiently and well, and was very courteous. Great service and for a reasonable price. Will definitely call Cost U Less Plumbing & Drain in the future when I need a professional plumber. Thanks Pablo!"

"I contacted the company. I got a call back from Manuel. I explained the problem. He came to the house within the hour and we agreed that the job would be completed today. We got a broken pipe in the garage fixed and a water pressure regulator installed. Then we tested the faucets and I was very happy about the water pressure and no leaks. There is a cost that was a little steep but we pay with emergencies. I recommend the company and also Manuel. Excellent!"

"Really great customer service before, during and after the service call. Instilled confidence. Provided simple solution to dramatically reduce the time it took to get hot water to the primary bathroom. Planning to work with them to install new high-efficiency water heater system in the near future. Compared to other plumbers I've worked with in the past, Big Blue is HIGHLY RECOMMENDED."

"I highly recommend the company (Costello's Plumbing) as well as the employee who helped us (Miguel). My wife spoke with Mr. Costello this morning, and booked an appointment for Miguel (one of his workers) to come over and look at the situation / prepare an estimate. He did so (arriving iwihin the appointment window), gave us a good quote, and indicated the two parts that needed replacement (the garbage disposal unit and the cold water dual shut-off valve. He indicated that we could purchase those parts through the company, or if I had the parts onhand, he could just install them (saving money). Fortunately, The Home Depot nearby was open, and I was able to get the two pieces fairly quickly. Miguel then: * installed the garbage disposal (and took care of getting rid of the old one), * connected the replacement shut-off valve, * replaced the faucet itself, and made sure that none of it leaked. A job well done!"

FAQs for water heater repair or service projects in San Lorenzo, 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.
