"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!"

"We opened this project through Angi on a Sunday afternoon, after our water heater started leaking on Saturday afternoon and completely stopped heating our water that night, I had been calling multiple plumbers with no luck (except high prices and a few day wait) the water heater guyz matched to us and called while I was still on the phone with the Angi agent! I called back Ty once I was off the phone with Angi, I then sent him a few pics of our water heater/water heater closet area and he was able to call me back and discuss a new tank vs tankless water heater. We decided to go with a new tank water heater and Ty then sent us an estimate that we signed and was able to schedule us for the next morning, Monday morning to get the water heat replaced! The gentleman Joe that he sent did an amazing job, very kind, efficient and professional. A few hours later we had hot water and 2 days later we had our inspection from the city. Great and easy process! Thank you again!"

"If I could give Mariano and his crew at Cal Finest Plumbing Inc a higher rating I would. The whole process, from the initial inspection/quote, through scheduling, and all of the work was handled with the highest level of professionalism. Communication was consistent and clear. Everything was thoroughly documented and shared throughout the process. The work was done well, efficiently, and as discussed/agreed upon. All while providing the best price for a large job (sewer and water lines replaced throughout the house). Mariano even helped us find someone to do a few other projects as well. HIGHLY recommended."

"The technician was supposed to be doing a plumbing inspection and draining the water heater. My wife was home; the guy was at my place for a total of 20 minutes and did not say much, then left. I wanted to talk with him about what he saw and some possible things to work on, but he just gave my wife the invoice and left. I am not an expert in any way, but I would think it would take more than 10 minutes to drain and inspect the water heater alone. But I would not know since I was unable to speak with him."

"Oak called 2nd but came next day/ UN-prepared to do either repair or water test (requested on phone) or even replace with ready new ADA toilet that the lying receptionist booker said they have “some in stock and if not he will show a catalog of choices”. Guy came punctually with Nzo tools or appliances Or knowledge of what I asked for as an “URGENT repair/replace”. See ABC review same call. Not quite as bad as them doing same since we also still have broken HVAC too, both said they would fix ( I bought gasket already, they could have put in) or replace if they brought new toilet. Problem is not in water pipes except they need testing for lead - both said they would do this too - when I asked oak re taking a sample, how long sitting in pipes? He wiped off his soda water bottle and asked “which pipes?” !!"

Water Heaters questions, answered by experts

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.
