If you are talking about the water heater anode/drain, mine is 1 1/16.

What Scott said ... make sure water pump is off or city water is shut off ... let cool a bit ... relieve the pressure by flipping the relief valve handle on the HWH ... stand to one side when removing anode as it will come out fast! Flip relief valve handle to original position and flush out sediment in bottom of tank.

They are 1-1/16" except for the ones that are 15/16" such as the one on every RV we have owned. I found a CAMCO plug with a petcock taht makes it even easier.
You do have to use some anti sieze or Teflon pipe tape on the threads of that gadget as it may freeze in place from dissimilar metals electrolytic problem.

Dave W ... Suburban HWH have steel tanks and need the anode, thus the larger wrench size. Atwood HWH have aluminum tanks and don't need the anode rode, thus the smaller drain plug. It depends on the brand or model of RV as to which is installed, but all my HWH on my Montanas since 2000 had Suburban tanks. $$ from the supplier of either heater could change future installs.

Yep, you are 100% correct. They all have Suburbans, that is except those that have Atwoods. I think that it's based on the time of the month or the phase of the moon as to what unit gets what, regardless of brand name..

I have noticed during my research that there are two types of anode rods, magnesium and aluminum. Which one for the suburban water heater.

You can use either one in the Suburban. I think it comes standard with a magnesium. My original was magnesium and it lasted only two years. Replaced it with an aluminum/zink and it went several years with almost no decay. Did not seem to be doing much good so went back to magnesium.

I too would go with the magnesium even if they cost more. They just seem to do a better job of what they are designed for.
