soldering copper pipe

[carl21l]

a trick to help soldering when ther is moisture in the pipes is to use a piece of white bread without the crust, make balls slightly larger than the opening in the pipes. push a ball into the pipe several inches to act as a stopper for the water. after solder re[pair, turn on the water, open faucets and the bread will be pushed out of the system by the water preasure.
it works for me.
