First use fine sandpaper to clean the inside of the fitting and the ends of the pipe. Then brush flux onto your fitting. Join the pipes together and use a propane torch to heat the fitting, not the pipe; that pulls the solder into the joint. If the copper turns black, it's too hot. Now, wipe off the excess, and that's all there is to it.
The plumber Steve Bowton shows Bob how to sweat a joint in copper plumbing. First he cleans the pipes with an emery cloth. Then he explains that plumbers no longer use lead solder and instead use a tin and antimony mixture to protect homeowners from lead poisoning. Then he puts flux on the pipes and the fittings. Places the fixture on the pipes and levels it, then solders the joints. The flux helps draw the solder into the space.
Plumber Jack O'Leary shows Bob how to sweat a copper pipe joint. Jack cleans the pipe ends and fittings prior to applying the flux and explainsthe purpose of each step.
Bob Vila meets with Carlos Leuchtmann from Blue Ridge Plumbing, who shows Bob the shower pan and layout of the new fixtures. Leuchtmann explains that the drain is off center due to structural supports in the floor that cannot be moved. Leuchtmann also points out the anti-scald restrictor and the dual-flow Moen shower fixture, which allows for either an overhead rain-type shower or a body spa with four wall sprayers. Leuchtmann shows Bob a tool for plumbers and electricians called the �stud popper�. The device makes a perfect hole in steel framing for running pipes or electrical wire. Once punched, the stud is fitted with a �pipe tight� that provides a feed for the pipes or wires and keeps them from touching the metal studs. Carlos also explains how sanding the pipe and adding flux creates a bonding surface for the solder to adhere to when sweating pipe.
Tom Higham is on hand to demonstrate how install copper plumbing for the bathroom lavatory. A copper T is used to join the various pipes. The pipe ends are cleaned and flux is added to ensure a good seal. Tom also gives a few tips on soldering.
Pinholes can be the result of the flux or too much head. You don't want self cleaning flux and you may want a water base. Flux is cheap. You could try another brand. Some plumbers will use only certain brands of fluxes and solders. When

the new copper pipe. Place the new length of copper pipe back into the vise. Use a flux brush to apply a coating of flux to the end of the pipe. Apply flux coating to the insides of both ends of the coupler as well. Put the coupler on the end
