How drain boiler for repair?

The paste is just a heat sink. Putting it on the iron fitting will just make the iron fitting soak up more heat. You can collapse the copper nipple in with a big pair of channelocks if you have to to free it up but i would just remove the male adapter and replace it with a copper coupler and piece of copper pipe to get the needed length.

If it was cherry that part was far more than hot enough, need to move the torch around some.

Oh, makes sense. But I would want to put heat paste on the tee’s joints, right? It would protect them from coming loose, but wouldn’t that act as a heat sink too?

Channel locks, squeeze to collapse nipple: WDITOTATFTT! (Why Didn’t I Think of That and Thanks for the Tip!)

As you sure there isn't any water in the tube as you try to heat it. Even a trickle, fast drip will prevent the tube from getting hot all around.

Jam a few slice of Wonder 🍞 Bread up the tube to temporarily stop a small flow. That's why they call it Wonder bread.

or use a shop vac to suck the remaining water out
