Default Re: Vinegar to detox and clean the radiator?

Joeway, they could be installed in a blockoff plate. I used a junk neck and all I had at the time was a thin piece of metal for the plate. Experiment with lye (drain-o) but don't leave it in to long maybe 15 min.

Pilotdave your correct, the backflush is in reverse. You would flush it from the bottom outlet back up into the radiator.

Be gentle with the air so u don't blow any tubes. Just tap the air at first to see how much water is moved out. Do it with a full flow of water going in from your garden hose.
