Is plumbing antifreeze harmful to HW tank?

I hope you mean the PINK RV/Marine anti-freeze....if so, no problem. But why it got IN the tank...a faulty fitting or "o" ring? Either way...you're ok...just be sure to flush it out either by draining the tank or hooking up a hose and letting it flush out via a faucet. Be thorough, tho.

Yes pink plumbing antifreeze. I blew a little into the tank winterizing. The manufacturer changed/updated the winterization procedure for our trailer. I had already winterized our trailer when I saw a post about an update to the manual. The update calls for the HW line between the bypass valve at the panel to the tank to be blown out. Because I had already winterized the trailer there was a small amount in the system. No problems with "o" rings or valves.

Thanks for your replies.

As long as you don't heat it you'll be fine.

No, it won't hurt the tank. Rinse well in the spring.
You could fill the tank with antifreeze if you chose, but it's just a waste of product.
