The Joint (Example)

Note: Capillary action is when a liquid flows in a narrow space without the affects of gravity influencing it.The use of joints in plumbing is a fundamental part of the job, because they are the connection that holds pipework together, guaranteeing that water, gas or any other flowing liquid does not spill or leak out, creating a massive problem in the home or even at work. One such joint is called a capillary type. It simply works by melting a soft soldering metal so it runs into the join between two fittings. This action is the one that gives the joint its name capillary. When the solder is cool it will form a secure and watertight join. Chessington Plumbers use capillary joints every day.This joint is available in a couple of types:Yorkshire:This type is called self-soldering, as it includes a ring of solder actually in the end of the fitting, and the direct heat of a blowtorch. Before use, the end of the pipework should be cleaned on the inside of the joint with some wire wool. Smooth some flux paste in the joint and on the end of the pipework. Push the joint together, and make sure that the pipe is in firmly. With a small pencil mark, you can check if there is any movement. With the blowtorch, heat the pipe and its joint and once you observe a thin silver ring of solder, thats when the joint is made. Use more solder if needed. A Chessington Plumber uses this type of joint End-feed:The end-feed joint has solder fed onto it when heated to form the joint. When the temperature is right the solder will melt and flow over the joint just like a liquid. Guide the solder into the joint until you see it gatherering at the bottom of the joint. Do not use too much that it drips. Allow the joint to cool completely before trying to move it.
