how am i supposed to find the sacrificial anode on my lochinvar LTN040G water heater?

I'm under the impression that you'd remove the sacrificial anode from the top but to remove the top it appears as though I'd need to remove some plumbing. I've searched for a manual that might explain but haven't had any luck. The top cover doesn't give any clues as to where the item might lurk below. Its @#$%& stupid.

Some anodes are “hinged”. They can be slid in and out without the need for large clearance at the top of the heater.

Looks like it's part of the outlet.

Wow - so the outlet tube and the anode are one and the same?

Here’s a different model that takes the same part and the exploded view is more exploded:

Installation-and a tip if you don't have enough head room to install new anode.

Oh, installed by an idiot! It would be normal for there to be a union joint so the water heater could be disconnected without unsoldering joints.

Replace with PEX?

After some research - seems that at least in some places you need 18" of copper before you can use PEX.

Yeah, where's the union?
In CA, there would be flexible connections to meet seismic codes. Loosen, bend out of the way, R&R anode, reconnect.

Why would you use PEX? Just cut out a section of copper and solder in a threaded pipe fitting. Then connect that to the water heater with a flexible corrugated copper pipe (which is designed for water heater connection). Sweat soldering is easy, but practice on some scrap copper tubing first. If you're scared of soldering, then use a sharkbite connector.

They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion." (1987) -- Carl Sagan

See my edit. I added the option of using sharkbite fittings instead of sweat soldering.

This looks like the manual - [www.lochinvar.com]

and this looks like a replacement part list - [www.lochinvar.com]

I'm still a little confused about how this outlet pipe relates to the anode and how the anode is removed. maybe it sits inside the outlet pipe?

I guess I need to figure out what diameter connections I need on each end of the sharkbite hose.
