If flexible pipework is used
Connect the pipe to the non-threaded side of the hosetail and secure using two jubilee clips
(See Fig. 7)
NOTE:
•
The hosetail may need to be cut depending on the diameter of the pipe.
•
Wrap PTFE tape or use silicone around the hosetail before connecting the
pipe to reduce the risk of leakage.
•
When using non-standard pipework, the first thing to note is that the smooth
end of the pipe will not fit into anything other than another fitting of the same
brand. You will have to cut it off. The hose tail will push fit in to the cut end
of the pipe, but it will not be watertight. You can put two jubilee clips on it
but because of the ridges in the pipe it will not squeeze down tight. It will
need to be sealed with a bathroom type mastic sealant.
