"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."

"I had an excellent experience with D G Plumbing and would highly recommend them to anyone in need of plumbing services. Their team was extremely professional, knowledgeable, and efficient from start to finish. They took the time to clearly explain the work that needed to be done and ensured everything was completed to a high standard. What really stood out was their fair and transparent pricing - no surprises, just honest and reasonable costs for quality work. It’s not always easy to find a company you can trust, but D G Plumbing definitely delivers on both service and value."

"They were very prompt, polite, and professional. My water heater was in a tricky spot . He ended up needing to disconnect a few things related to my furnace as well. They did it without charging me anything extra and When they were done, everything looked and worked great."

"I hired Alvco for a plumbing repair I highly highly recommend Alvco. This is a family owned and operated entity. Tim and his brother are superb at all aspects of the business from technical expertise, on time arrival, and genuine customer care. They did a water heater replacement for me same day. They did not charge me extra for the rapid response and they quadruple checked their installation to ensure every aspect of the job was correctly executed. I also asked Tim to change the dimension of my heater as the outgoing unit i felt was to big for the closet it was located inside of. He fully supported my request and and now the new unit looks perfect. Tim and his brother are exceptional. I will use them on all my plumbing jobs going forward."

"Called Trio Heating on a late Friday afternoon and they sent out two technicians (Jose & Dallin) the next morning to fix a gas heater that would not turn on. Their communication from beginning to end was great. They sent me a text 45 minutes before their arrival time and I was able to track their ETA which was extremely helpful. They explained to me what the issue was. I was able to run out and buy a new thermostat for them to install. They did a great job, cleaned everything up and put everything back together. They also typed up everything they worked on and took multiple detailed photos of the unit and emailed 10 minutes after they left. I think what they charged was extremely reasonable for the quality of work. I really appreciated not being charged a higher fee for coming out on a weekend. Will definitely use them again for my HVAC needs!"

Water Heaters FAQs, answered by experts

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.
