Unit 109 Copper Pipework

End-feed components

• Elbow: Named after the shape of the fitting, it allows the pipework to change direction by 90º.
• Reducer:This allows the connection of a smaller diameter of pipe.
• Stop end: This is basically a cap that can seal the end of a piece of copper pipe

• Solder ring These fittings are classified as non-reusable because once they have been soldered in position they cannot be moved. If necessary, they can however be re-heated to release the pipe from the fitting.

• Push-fit These fittings require care when being installed as they rely on an internal rubber O-ring to create the water-tight seal. They are simply pushed on to the copper pipe, where the grab teeth inside the fitting keep it in place. A square and clean-cut end to the pipe is needed to avoid damaging the O-ring.

• Push-fit These components are produced by many manufacturers and come in different finishes.

• Push-fit When installing these push-fit fittings onto copper pipe there is no need for the use of a sleeve or insert as the copper pipe is rigid. If they are used on plastic pressure pipe then a sleeve is required to give the pipe added rigidity.

Joining copper pipe

• Compression These fittings are classified as reusable because they can easily be released by the use of an adjustable spanner. The olive is compressed to the pipe and will need to be removed to allow the back nut to be released. A replacement olive will be required next time.

Joining copper pipe

• The two most common sizes for domestic pipework and fitting are: 15mm 22mm Both sizes of pipe can be purchased in 3.0m or 6.0m lengths, either in a bundle of 10 lengths or as a single length.

Joining copper pipe

• Installation When copper pipe is installed in a property, it is required to be correctly supported to avoid any sagging or movement of the pipe, whether vertically or horizontally.

Clipping distances Required clipping distances for copper pipe:

• Clips There are many different types of clip available for copper pipe and each is designed for use in specific situations. They all perform the same functions, however: To prevent sagging To prevent noise To prevent movement and damage to the pipe and fitting
