General Specifications

Operating pressure range (bar)

NOTE:- Nominally equal (balanced) inlet supply pressures are recommended for optimum

performance of mixer taps.

BS 6700 recommends the temperature of stored water should never exceed 65°C. A stored

water temperature of 60°C is considered sufficient to meet all nominal requirements and will

minimise the build up of lime scale in hard water areas.

the diameter of the inlet pipe to the fitting, whichever is greater. If the fitting cannot be installed

as indicated it shall be installed:-

a) With a backflow prevention arrangement suitable for the Fluid Category or

b) So that it draws water by gravity only from a cistern, cylinder or tank having a

permanently open vent pipe, the vertical distance between the point at which the pipe or pipes

supply water to the fittings is or are connected to the supply and the spill over level of any fixed

appliances is not less than the dimensions stated above, and the vent pipe or pipes supplies no
