Good But Loud

Would Recommend

Had to replace my 10 yr old water heater. This new unit gets hot, but as the unit is going through a cycle, there is a loud thumping sound which repeats for about a minute, then stops. Otherwise, this would be the perfect unit.

repairing less than a year

Would Not Recommend

I am now changing the gas valve on this AO Smith tank 6 months after replacing my Rheem tank. I could not control the water temperature. I had it set between low and vacation mode. The temperature was 150 degrees (scalding). They sent me a new valve, I installed it but it is still hard to get the temperature to a steady 120. It fluctuates to much. I will use this tank till the warranty runs out but I will not be buying an AO Smith tank again. I asked the rep on the phone if others were having th...

Leaked immediately

Would Not Recommend

I purchased and installed this water heater in my basement. I installed a new pressure relief valve on my water line and added a new thermal expansion tank. Installation was straightforward and the unit fired up just fine. But on the first heating cycle, the factory installed inlet nipple started leaking from where it attaches to the tank. It’s a slow continuous leak that pooled water under the heater. I attempted to tighten the factory installed nipples, but the leak continued. I called the AO ...

Bad Experience

Would Not Recommend

We ordered this hot water heater online from the Lowe’s website on 11/24/2025, and it was installed the next day on 11/25/2025. Since then, we have been trying to register it on the AO Smith website, but we cannot locate the serial number anywhere on the tank. There is no sticker showing the model number or serial number. Our other hot water tank, which is installed right next to it, does have a clear sticker with all the necessary information, so this issue is specific to the new unit. We are ...

Second One

This is the second water heater of the same type that served my family very well for many years. Thus I decided to buy and install the same type. Installation was very straight forward and easy.

Quick and quiet!

Would Recommend

Only installed a week ago, but so far it’s working awesome. Straight forward to install, started up with no problems or drama, and has been quietly pumping out hot water since. The heater itself is pretty much silent except for the exhaust fan running. It is about the same noise level as the pre-draft motor on most furnaces. So it is very quiet for what it is. This is my first AO Smith, but I worked as an electrician for one of the big three automakers for almost 40 years, and AO Smith was all t...
