So far so good

Would Recommend

only installed a month and so far so good we shall see. The guys at Lowes were very helpful and polite. None on the floor but in stock on the high shelf and they worked quickly to get one for me then checked me out right there. Now that was easy!

Would Recommend

I had an AO Smith 50 gallon water heater installed 14 years ago and did not have any problems. Of course I was going to have a AO Smith water heater installed again!

Ridiculous!

Would Not Recommend

$600 for a $300 water heater that won't last 10 years. Absolutely Pathetic!!!

Anode unable to be changed

Would Not Recommend

Heater is 2 months old and cannot change zinc anode to aluminum even with 800 ftlb dewalt impact wrench. of course Lowes does not support the product and referred to AO smith who does not have a page on website to start warranty claim. Good grief what a joke

Nice water heater

Would Recommend

Picked this water heater up because my old one was getting old and was seeing some rust coming out in the tub. It’s a very nice water heater for the money. Heats water fast.

Compact and easy to install

Would Recommend

The water heater was thinner and taller than my old one, so it took up less space, it was easy to install and all fixtures were easy to access. Filled and heated up very conveniently. Happy with this product so far.
