Water heater age?

RUUD RUO 570 73257.

I’m thinking 1970, but my references don’t give that format.


May 1970 is what I get Frank

Yup, Jim’s got it.

I was pretty sure that was it, but just thought I’d ask to be sure. Thanks

A 40 year old water heater? Pretty good. Oldest I’ve ever seen is 32 years. A record :slight_smile:
