When using non locked rubber seal joints or mechanical couplers, pipelines must be anchored at each
change in pipe direction, to prevent the pipes coming apart.Sideways movement is prevented by clamping.
Where mechanical couplers are fitted, sideways movement can be avoided by scuring the coupler itself.

Please note that rubber seal lock joints must be fully extended. This means that the locking strip is pinched
between the stop in the socket and the stop in the spigot end. This prevents movement of pipe sections and overloading
at bends and tees. Mechanical stretching is preferable; the results can be seen by inspection of the position of the
locking strip through the insert hole. Extending can also be done by pressurizing the main line (0.8 x working pressure).
Take care that the pipe sections are not pushed off their supports. In order to prevent this the lower part of the clip
should be tightened temporarily and the upper part of the clip should be loosened. Relocate any moved pipe clips
in their original position.After fully extending, the branch pipe sections can be installed.
