corrosive action on this union hot side
 
1 Attachment(s)
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:thumbup: 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.

What corrosion? I don't see any corrosion or electrolysis at all. All I see is solder tin Am I going blind Joe? Vat DA Hek Ar U Talkin Bout? :huh:

Admittedly, the guy cant focus (Macro Please) but aside from that, whaaaaaaaaaaaaaaa?

That is a new heater, I wiped the corroison off. I will have to wait till or if it comes back and take a photo before I clean it off. Thanks for the response till next time.

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----
