"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!"

"Perfectly. They cleaned everything up, explained how the system worked and how often it needs attention, and hauled away the old hot water heater. They arrived on time, worked steadily, and finished before dinner time."

"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."

"They had a good program for heating and A/C like for $100 they come out and check in the fall to make sure the heating is running right and again in the spring to make sure the A/C is working right. They did their job. It was cheaper than anyone else and I got 2 services. The only thing they could do better is give me free heating and air conditioning."
Our team at Bonney helped restore flow at this Sacramento home by performing a sewer spot repair on the main line for our customer.  This involved locating the problem area, digging the trench, snaking the line to clear the drain, repairing a section of the sewer pipe, and then backfilling the space to restore back to the original landscape.

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