General Information
This product has been tested to the Water Regulations Advisory Scheme (WRAS) and
satisfies the requirements of the Water Supply (Water Fittings) Regulations 1999 and
current bylaws. For full Installation Requirements & Notes (IRN) please visit
www.wras.co.uk/directory.
Designed to comply with BS EN 200 for combination taps to be used within systems
designed to BS 6700.
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 normal
requirements and will minimise the build up of lime scale in hard water areas.
If installing this product on a low pressure (tank fed) system please see specification
table below to determine the minimum distance required from undeside of the cold
water tank to the outlet.
These taps and mixers should be installed in compliance with the Water Regulations.
Where the supplies are unbalanced, i.e. Hot water from cylinder tank / cold from the
mains, approved check valves must be fitted in the supply pipes.
For further details contact your Local Water Authority.
