Welcome to irv2 MasterKrafRV.
Thanks for added information about the Atwood water heater.



My question would be how do you drain it, in this picture do not see plastic plug?

Atwood XT Brochure - http://www.atwoodmobile.com/images/waterheaterxt.pdf

Atwood XT Manual - http://www.atwoodmobile.com/manuals/...S%204.9.09.pdf

As shown in the brochure, in order to increase the apparent quantity of available hot water, Atwood increased the temperature inside the tank from 120 to 160. They added a mixing valve at the output to mix the high temp water with incomming cold water to provide a 104 degree output temperature.
The Atwood gas/electric version uses a 1400W (11.6 AC amps) element which is way above the hott rod 6 gal 400W (3.3 AC amps) / 10 gal 675W (5.6 AC amps) rating. Because of the much larger AC element, the Gas/Electric Atwood version should be connected to it's own 15 amp AC breaker.

As shown in the Installation/Operators manual, the drain plug is located above the gas solinoid valve. Winterizing procedure is slightly different from other models but is basically the same.

Regarding the original questions related to this thread, here is the explanation provided in the Atwood Training Manual as to why you do not need a Anode rod:
Quote:
ATWOOD CLAD TANK
The Atwood water heater tank is constructed of a core of high strength aluminum. The interior of the tank consists of a 15% thickness of type 7072 aluminum (pure aluminum and zinc) that is fused to the core during the rolling process. This material protects the tank from the affects of heavy metals and salts found in waters throughout the country. It is anodic to these heavy metals and acts much like an anode in a steel glass lined tank except it will last much longer. There is also no need to replace an anode on a yearly basis.
Flushing the tank on a regular basis has been found to be helpful in insuring the best performance of your water heater and adding to the useful life of the tank. For flushing instructions see your owners manual or contact Atwood for a copy of our recommended procedures.

It does have a nylon drain plug, it should not be difficult to find. It does not "melt" to keep the tank from rupturing, that is the job of the over-pressure valve near the top of the tank, as seen in the picture Roger provided.

Drain plug is located slightly below the center line of the gas valve/venturi to burner assembly and to the right of the gas valve. Most use a 15/16" socket but I have found some having the 7/8" plastic/nylon plugs.

Da** sure glad I became a member of irv2. In this case, the what ever it is, inserted into the drain of my Atwood WH actually has a factory electrical connection - component yet to be determined. The big question will I remove the devise and replace it with the proper plug or be forced to replace the WH because what I have was never supposed to be?

I have worked in industrial automation for more than 40 yrs., but have rarely seen issues from such simple equipment.

Comparing the RV's I have looked at (and own) to the sailboats I have owned: the RV's are under engineered for longevity, and for the most part, use materials more suited for a stationary mobile home than a vehicle expected to move down the highway at speeds > 60 mph. If the boats I had owned had been built with such standards, they would have probably sunk during the first time they were away from the marina in less than ideal conditions.

For a time I thought I was being too critical of the RV's. At least with irv2, I can see others are dealing with the same issues.

Atwood aluminum tanks do not require a anode. From the original post i did the same thing and replaced the plug with a hose. Got tired of cutting my knuckles getting out the nylon nut. Click image for larger version

That is exactly what I was thinking would happen. Aluminum is subject to galvanic corrosion when in contact with most other metals. That is why they use a plastic plug. I have wondered alot if the tanks could be made of glass instead of metal. Probably could but the cost might be prohibitive.

mrt_1111,
Thanks for the input. I haven't pulled the component yet; but judging by the wiring this could be it. The wiring has corroded and is disconnected from the element. At this point I plan to remove the wiring and replace the rod heater with a nylon plug.
