2. Connect a length of grey tubing (supplied with the valves for use on

the valve barb fitting) between the hose barb on the valve and the
inlet connector on the isolator (Figure 2.9). If more than one isolator
is supplied by a valve, use “Tee” connectors as required (Figure 2.10).
Connect the grey tube from the valve to the “Tee” and use translucent
tubing between the “Tee” and each isolator.
