Cold Water

Combination Valve

The cold water combination valve may be fitted in close proximity to the

cylinder, or alternatively, it may be separated to allow the pressure reducing

valve where the mains supply enters the property allowing for balanced cold

water throughout the whole property whilst the 6 bar safety valve is fitted in

close proximity to the cylinder.

A balancing port is supplied on the 22mm and 28mm valves allowing

balanced cold water supply to the rest of the building giving constant results

for mixer and shower valves. If the facility is not needed a plug is supplied.

Refer to Fig. 3.8 and Fig. 3.9

Note!

There should be no other valves fitted between the cylinder and the

EXPANSION valve.
