How to Sweat Copper Pipes : Dry Fitting Copper Pipes

Hey everybody Don Golden here with Expert
Village. We are talking about copper piping and copper fitting. We have prepped these
two little demo pieces and the 90 degree union that I am going to show you how to sweat shortly
but I got a little ahead of myself in that we had already applied the flux paste before
dry fitting. Now dry fitting is a term that sounds exactly what it is. You want to fit
these together before you put anything on it especially the solder. If you have two
valves that you are joining and you are a little off in your measurements and you have
already soldered them then you have got to start all over again. A dry fit is simply
what it is, you take each piece and put it together and if point A goes with point B
exactly where you want it then you are ready to go. It is very important that you dry fit
all of the copper pieces and there is going to be a lot more of this whenever you are
doing a job. That’s it for dry fitting.

  1. Tip from the pros: NEVER dry fit, your tape measure doesn't lie so there should be no need to dry fit. NEVER place a newly fluxed piece of pipe on the table or work area where it can pick up dirt and debris which will defenitely cause a leak in your joint. Stick it in the socket immediately. Lastly… use as little flux as possible because the more you use the more it drips and runs and the more heat needed to solder. 🙂

  2. where the hell did he find that copper that has to be the dirtyiest shit I have ever seen/ plus is that flux lead free?????

  3. He the wires show and tell guy I have ever seen…if he clears his throat one more time I'm gonna throw up…
