corrosive action on this union hot side


Why would there still be corrosive action on this union hot side? The plastic bushing and rubber washer is in tact. I wiped it off so the corrosion is not showing. The old heater was in service 20 years no corrosion, same set up.
Just on the bottom of the union!

Anodode rod is probaly long gone with a heater that old.
20 years is about 5 years behond the expected life of a heater, may want to concider replacing it.

Might be a tiny bit of seepage---the threads are just raw steel---they can pick up some rust from the atmosphere

I ALWAYS use anti seize compound on something like this. I pulled the anode on my new water heater prior to install, applied Nickel based Anti seize compound and reinstalled it. I picked this us while servicing burners on huge stills in refinery's. That stuff is worth its weight in Gold.

I was thinking flux may have run down, it was a straight line run rust colored so who knows. I can't help but look at when I was clothes as it is right there.

I've seen that area stained from the union--seep a bit and obviously was tightened----
