Annode / WH plug

[Terryallan]

Won't come out. So I opened the low point drains and let the water out that way. On my old TT, that drained the WH as well. But I really can't tell on this one, If the WH drained or not. I can say. Water ran out of the low points for a good long time.

Then blew out the lines, with all by pass valves open. Only got air out of the faucets. Think I'm good to go

Nope it's back in. Not taking a chance of something making a home in the water heater. I'll get a new one in the spring. Have too. It's pretty well gone near the threads. It's only in it's second year. Seems like it getting used up awful fast.

No need to replace until sacrificial material wrapped around the steel core has deteriorated by 75%......still doing it's job and the steel core stays intact.
Just remove, clean 2X a year.

Hook up to city water and let it start to fill your water heater tank with the anode rod out. Then use a small steel wire brush in it to clean the rust out of the threads. Turn water off and then run the anode rod in and out a few times. Turn water back on and clean it again with wire brush.

When you put your anode rod back in, use thread tape or similar liberally and it will help keep them from rusting together so bad.

I use an extension rod (so I have 6-12 inches longer length), big socket wrench, and the usual socket. So far, I've had decent luck in breaking mine free, although I always wrap the thing up with Teflon tape before it goes back in so I can get it out easily next year.

Been a year since last time........so you might want to change that to twice a year.

Yeah. I'll get it out. I put some penetrating oil on it, let it sit, and try again. Felt like I was picking up the entire TT this time.

And it has only been since I last winterized it last year that the plug has been in there. But I guess it rusted in place.

And I did run the air thru the water heater.

When I opened the low points. Water ran out for like 15 minutes, That's why I though it may have drained the WH too.

If you can borrow an electric rattle wrench, i bet it will spin right out.

I needed a 2 foot pipe on the end of the breaker bar... to get mine to turn.

but I did not tighten it back as much.

Sooner or later you will need to replace the anode. You might as well get it out now, using a bar and Skip's trick to remove it. Once out, the teflon tape works for me, to aid in removel next time, as well as make a good seal.

One trick to removing the plug is to tighten it more then take it out

IF your WH doesn't have check valves in the lines:

Pressurize the system with air into the city water connection. Disconnect the air hose, the check valve in the city water inlet will hold the pressure.

Then open the low point cold drain.

Repeat as necessary. The WH will get an air bubble in it and force the water out the cold inlet (if it doesn't have a check valve.)
