need to solder the joins using a blow torch and solder.
Follow these steps to find out more:
1 About compression fitting
2 Removing the nut and olive
3 Assembling the pipe and fitting
4 Final assembly
Tools
Adjustable spanners.
Materials
Compression fitting, prepared copper pipe.
Step 1 - About compression fittings
Compression fittings are an easy method of joining pipes
and appeal to the occasional plumber. No specialist tools
are required other than a couple of sturdy spanners and a
hacksaw.
Step 2 - Removing the nut and olive
The fittings are made up of the fitting itself, a nut
and an olive. The nut screws on to the fitting and
compresses the olive against the pipe to give a
watertight seal. Remove the nuts and olives as shown.
Step 3 - Assembling the pipe and fitting
Pipes must be clean and free of burr before you fit them.
Use a pipe cutter to attain a clean cut. If you would like
to know more, click the icon below. Insert the pipe through
the nut and olive. Push the pipe into the fitting and
hand-tighten the nut thus slightly compressing the olive
ready for the final assembly stage.
Step 4 - Final assembly
Hold the fitting firmly and tighten each nut in turn.
Once you turn the water back on you will need to check there
are no leaks. If there is a slight leak you can simply
tighten the fitting a little more. If this does not work,
turn off the water and check that there are no serious
score marks on the ends of the pipes and re-assemble carefully.
