The PRV valve should be fitted
with service taps that allow
maintenance whilst the PRV is in
operation.
An example is shown opposite.
Choose locations to be used for
attaching any Sentinel pressure
transducers and also the water
feed to the Hydroswitch inlet
port.
Ensure these service taps are
closed to allow work to proceed.
Fit Y-adaptors or quick-release
connectors to the PRV, as
required, to allow connection to
Sentinel 2 at a later stage.
Do not fit any hoses or pressure transducers to the PRV at this stage.
Stop Taps (for service):
Close those required for transducers and
water feed to Hydroswitch solenoid valve.
