Marc Posted April 9, 2013 Report Share Posted April 9, 2013 Click to Enlarge 68.5 KB Click to Enlarge 34.23 KB Serial D4264-2G05479 I'm thinking either 64' or 79'. No aluminum conductors, ground wires in romex, copper fresh water supply, steel & cast iron DWV. Built on a slab. No numbers on WH gas valve. Doesn't mesh with TIJ decoder...that I know of. Thanks Marc Quote Link to comment Share on other sites More sharing options...
AHI in AR Posted April 9, 2013 Report Share Posted April 9, 2013 Styling clues look earlier than 1979. But a unit from '64 still working? Were they one of the companies using aluminum tanks then? Quote Link to comment Share on other sites More sharing options...
Richard Moore Posted April 9, 2013 Report Share Posted April 9, 2013 I don't think they were still stamping the data plates like that in 79. The last "glass lined" oldie I found was from 1965 (still working in a 1965 home). If those serial numbers on yours can be decoded, then best guess would be week 42, 1964, perhaps plant "D".

hausdok Posted April 9, 2013 Report Share Posted April 9, 2013 Hi, I just spent nearly half an hour on the phone with the current American-Standard Company. They are now based in California. The new serial number decoding sequence is coming email and will be added to the chart. They tell me that the water heater division used to be based in New Jersey and manufactured tanks in New York and that they stopped producing water heaters many years ago - although they don't know exactly when that was. Kim, the lady at their office says she thinks it was Burnham that bought out the water heater division but she's never been able to confirm that because Burnham has been unresponsive to her inquiries. She says that lots of folks call her from all over the country with tanks that are in 1950 and 1960's homes looking for manuals and say those tanks are still going strong, so she's quessing that your tank is from the 60's, possibly older. She says some of those older tanks are copper. As for their current models. They reinitiated tank manufacture in 2000 with commercial tanks and didn't get back into residential until December of 2007. I'll have that coding added to the chart after I receive it. ONE TEAM - ONE FIGHT!!! Mike Quote Link to comment Share on other sites More sharing options...
MMustola Posted April 9, 2013 Report Share Posted April 9, 2013 Was the TPRV installed into the side or the top of the tank? If so, most likely 1979. If the valve was in the outgoing hot water pipe than mostly 1964. Quote Link to comment Share on other sites More sharing options...
Marc Posted April 9, 2013 Author Report Share Posted April 9, 2013 Was the TPRV installed into the side or the top of the tank? If so, most likely 1979. If the valve was in the outgoing hot water pipe than mostly 1964. TPRV wasn't on hot water outlet. I've never seen one of those down south, just in photos. Thanks fellas. I feel solid about 64' now. Water quality very good here. Added to the track record Mike mentioned and that's probably why it's still in service. It also dates the house for me. Never heard of aluminum tanks. Not aware of any down here. Mike O, I appreciate all your time. That's a lot of work for you. Marc Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted April 9, 2013 Report Share Posted April 9, 2013 Because the label has "American Radiator & Standard Sanitary Corporation Plumbing & Heating Division" it has to be before '67. That year and later it would read "American Standard Corporation". Quote Link to comment Share on other sites More sharing options...
Marc Posted April 9, 2013 Author Report Share Posted April 9, 2013 Thanks Bill. That's my proof. One of these days, you're going to post on how in the heck you catalog all that information.[] It baffles me. Keeps me awake even. Marc Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted April 10, 2013 Report Share Posted April 10, 2013 The address uses the old postal zone numbering system. Those were used from 1943 to 1963. Perhaps a few years later, but not much. In 1963, zip codes were introduced and pretty much took over. That tank is at least as old as 1964, and probably older. Quote Link to comment Share on other sites More sharing options...
