Hot water anode rod.

Does anyone know what size socket is needed to remove the plug to change the anode rod in the hot water tank???

It's a 1 and 1/16 inch socket. Be sure to use an extension on your socket wrench, least you want cracked knuckles.

I'm checking/changing mine today as well. I'm curious what it'll look like after 10 months of Fulltiming in the Redwood. I also suspect my RO system might cause the anode rod to rot away a little faster than normal.

We replaced ours after 14 months and it wasn't anything but a bare wire. However, I have to question its usefullness as the hot water tank is aluminium and not sussepectible to corrosion. Maybe, it's protecting the electric heating element? Anyway, checked our current element and it just had some calcium buildup on it.

I highly recommend flushing the hot water tank twice a year with one of these. You'll be amazed how much crap comes out.

So the Suburban tanks are AL? Maybe it's the internal components its protecting?

Just replaced the anode rod. It wasn't too bad, about 50% gone after roughly 10 months of constant usage. Looks like once a year will be adequate for me. The tank wasn't terribly dirty either. However still glad I cleaned it out, there was some nasty red water that came out that I suspect was from the few months I used the stock filter only.

I thought all Suburban tanks were steel? Aluminum tanks donot have an anode and use plastic plugs as steel is a dissimilar metal
