Question Can't find the anode rod to replace it

We have an A.O. Smith water heater, model # GVR 40 200. We need to inspect &/or replace the anode rod (we have all the right conditions to make the anode rods go very quickly; our last one lasted 2-1/2 years before the water heater broke and had to be replaced). Trouble is, we can't find the old anode rod to even inspect it.
There are 4 holes in the top of the water heater; water in, water out, T&P valve connected to a drain pipe(?) and a hole that has, at least, 3 inches of insulation in it (we haven't dug any further down in there).
In the manual, it kind of looks like it's underneath the T&P valve.
We are at a loss. Does anyone know where that anode rod is or how to get to it? Is it really under the T&P valve?
Thanks a bunch.

I'd dig down until you get to the tank. That's where I'd expect to find the anode.

No luck. Dug down about 10". The hole with the plug is near the edge of the water heater so I think it just runs down the side of the tank. I've been looking around and haven't seen anyone else that had to remove that valve to get to the anode but I'm not sure where else it could be. ???

Ummmm. Page two of the manual says:

*Location for optional top-mounted
T&P Valve if ordered from factory.



I hope that doesn't mean they've eliminated the anode --- I wouldn't think so.

They give a phone number for the technical services department of AO Smith on page two. Write down the model and serial number, call them and see what they say about an anode.

None of their other service literature answers the question of how the anode issue is handled if the top mounted P&T valve option is selected ---not that I can find, anyway.

Thanks for your suggestions. I agree and don't see the info in the manuals. They were closed by the time I called but will try again soon and post what I find out.

It could be a combination nipple/anode rod in the hot water outlet.

Could be, I suppose. Never heard of 'em though.

When I called she said the anode is under the hot water nipple so it sounds like I ordered the wrong type. I bought the hex and not the combination. Thanks for your help. I'll see if I can return it.
