    Rated 5 out of 5 by from Original Worked great for 10 years! My. builder installed the same unit in 2012 and it has worked flawlessly. It probably would have worked longer if I had changed out the anode. Weeks ago the tank developed a small leak and I replaced it with this current model. I was slightly disappointed that neither the control box nor the temperature/pressure relief valve were installed pointing exactly "down" so I had to rework the drain pipe to fit. Other than that it was easy, fired right up, and heated the water completely in under 45 minutes. Ordering on-line was easy, and pickup at a nearby Ferguson warehouse was a breeze. It was the best price I found for a 50 gallon water heater too.

    Rated 5 out of 5 by from Great product This is a replacement to the state hot water heater I purchased 13 years ago. The replaced water heater was working fine. I got a new one because of its age and the fact that is in the attic area of my home. I didn’t want to take any chances on a leak….

    Rated 5 out of 5 by from Solid Water Heater I previously had a State Water Heater and although it failed after 10 years it was a very good product, never having any issues delivering hot water to our 3 showers and 6 sinks. That's why I opted for the same brand again and the quality is second to none.
