Hot water heater drain?

Anode rod, yes it needs to be replaced when it gets close to the steel core

That is your anode rod. do a search on it. lots of info. It basically saves the inside of your tank from being eaten.

That's your anode rod. It is a sacrificial rod that is eaten away by the electrolysis of the water, rather than eating away at your water heaters tank.

Here is info on when it should be replaced.

I've also attached a manual for you.

When you replace the anode rod, use Teflon tape on the threads.

While you have it out, use your hose to flush out all the white crap in your water heaters tank. Some folks buy a plastic wand that goes on the end of their hose to stick in the hole to help flush. Others buy a washing machine hose, cut it in half, and put it on the end of their hose and stick it in the hole to flush out the white crap.

The white stuff is precipitated calcium and such. Won't hurt you, but can clog stuff.

Just did this today. I used my water tank filler. Fits perfect. Amazing how much white junk comes out.

There's at least 3 long anode rod threads going right now.
Always happens when people start winterizing.

Manufacturer sez

Manufacturers say no more than 1-1/2 wraps and not to tighten the plug more that 7-8 foot pounds which is not a lot. Just so it don't leak. Multiple threads don't bother me a bit. If they bother you, go fishing.

Anode rod

A quick question: since the anode rod comes out with some scale on it, is brushing it with a brass brush advisable?

Cant say the impact of brass on Magnesium, butmI just scrap mine shiney with a razor knife when I pull it.

While we are in the "wet world" here, I keep my blue ext water filter in the garage freezer btw road trips. Should help cut down on uglies growing in it....

Have you run your WH on electric? If you have, you probably have scale on the heating element. If there is a lot, it will slow down heating the water and may cause whistling sounds.

I've taken to soaking the WH with a 50/50 solution of water and vinegar. Drain the water heater and then use your winterizing port to suck in the vinegar solution to fill the tank. Let sit overnight or heat it up and let sit for an hour before draining again. Don't forget to release any pressure buildup before removing the plug or anode. Ask me how I know.Ö

Here's a link to for the Love Your RV folks on doing this...
