Water heater replacement time. I will be installing a "short" 50 inch heater, similar to what I have. In the future, when anode requires replacement, can I install a segmented "flexible" anode in any manufacturers water heater? I am considering IO Smith and Rheem. Thanks.
Segmented/flexible anode?

Yes, I think so. Some anodes use a hex plug with a 1-1/16 head and a 3/4 NPT thread. Those typically require an impact wrench to get the old anode out.
The other type integrates the anode with a nipple. That does not require an impact wrench, but does involve working with the piping if you don't have a flex connector. Most such nipples are 3/4 inch thread, but I think a few are bigger. Some WHs even have both nipple and hex types.

If you get a sulfur smell in your hot water, consider looking into a powered anode. Search for that term with the search box above.

Thats good info, thanks. My current Bradford White must have a nipple type, as there is nothing on the top of the WH except 2 nipples and the flue. It sprang a small leak that I can't see and is 13 yrs old, so I think its best to replace it. I do have flex lines to the WH. Anyway, anyone else care to chime in?
