Remove the toggle on the cold water
shut-off valve (if installed) to prevent
anyone shutting it off manually.
Shock arrestor
If draw-off points that could cause pres-
sure peaks (water hammer/shock) are
connected to the same pipework as the
boiler (such as pressure washers, wash-
ing machines or dishwashers), we would
recommend the installation of a shock
arrestor near the source of such pres-
sure shocks.
g
: Fit a small domestic expansion ves-
sel if water hammer occurs.
