Water heater anode rod?

Well I did my first winterizing this weekend, just before the big northeast snow storm, and to my surprise when I pulled the plug to drain the water heater, there was no anode rod. Just a plastic plug. One of my friends told me it might be an aluminum tank and not need an anode. Is this true? Or should I replace the plastic plug with an anode rod in the the spring when I de-winterize?

Your correct, no anode rod required. Just clean the plastic plug and reuse, or install a new plastic plug.

Here is another thread on the same subject for reference: https://www.jaycoowners.com/showthread.php?t=4788&page=2

Thanks for the reply. Sometimes I forgot how useful the search button can be.

I have seen many places recommend installing a new plastic plug every year. They are really cheap so I keep a spare set on hand. Finishing up my second year so I am overdue, I will throw in a new one this spring.

I don't understand why a plastic plug that does not have damaged threads or a damaged hex end would ever need to be replaced. Any theories on this?

Sure........,the plastic plug will require a little extra turn of the wrench each time it is reused in order to get a good seal. I would also guess the continued hot/cold temp swing will compromise the plastic plug over time as well.

Even using plumbers tape on a reused plug doesn't guarantee there will be no leaks...been there, done it.

Like Terry, I keep a couple on hand....., seems someone is always in need of a new one

I had one blow out a few years back with another rig. It is easy to damage the plug when re-installing it.

They are cheap insurance.

Also - plastic does deteriorate over time so the threads may weaken. Just a good maintenance habit to get into in my mind. I would hate for the plug to release and dump all that hot water if someone was nearby. Would probably not do too much other than really make them mad.

I think I paid $4 for a 2 pack on ebay last year. Why not for a couple of bucks.
