From what I know and have read, it shouldn’t matter. I just used the only kind they had at the RV shop.

Aluminum or Magnesium anode rod, does it matter which I I use? and where can I find it out if it does if I don’t have a manual for the heater. I have a used trailer and just winterized it and drained the heater, I saw that I will need to put in a new rod when the season starts up, but I’m unsure which I will have to use and I don’t have the user manual.
Thanx in advance for your help

Good question! I have no idea. Sorry, but I suggest you ask at your local RV dealer or service shop. I’m no technician.

Why do water heaters (that don’t require anode rods, believe they are aluminum) have plastic plugs? I am continually replacing these. Can I use a copper plug?

Good question! If there’s no water in the heater, there’s no reason you couldn’t just leave the anode rod in there. Otherwise, a plastic plug should be just fine. Or, cut the anode off next time you change it and just use the plug end. Thanks for asking.

My travel trailer sits idle on site all winter so I drain all water and use the bypass so anti-freeze doesn’t get into hot tank. What is best for the anode rod opening from the outside for the winter? Plastic plug or what?
