"I was very impressed with Mr. Chris Massey! I placed a call to him at about 9:10 in the morning to request a quote for a hot water heater replacement. I received his voicemail; however, within only 20 minutes he called me back and was apologetic for missing the original call. I could sense at that point that he was a sincere individual. I explained to him that my electric water heating unit was located in my crawlspace. I also provided him with the dimensions of the tank and its accessibility in said crawlspace. He responded as if he had completed these type of projects countless times in the past. Without even looking at it he gave me a quote right there over the phone. After doing some research I knew that it was a very reasonable one so accepted it immediately. He then told me that he could pick up a new unit and be at my house by around noon. He was actually pulling into my driveway before 11:00 AM. He finished the whole removal/installation process in under two hours and filled me in on everything that he did. He was intelligent, personable and quick. I'd give him 7 stars if I could. This gentleman is truly a class act!"

"The owner and co-worker came out yesterday for a quote and they were very honest and professional and being that they had really great reviews, I went with them. They came out today and had the work done in 3 hours (we had a hot water heater relocated from our laundry room to the garage) and fixed 2 outside faucets that haven’t worked in a long time. With that being said, when I say they were professional about everything, they were! There was no mess from them at all, they cleaned as they went which goes a long way in my book. I would definitely recommend this company to anyone that needs any sort of plumbing work done."

Water Heaters FAQs, answered by experts

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.
