Water Regulations Requirements
It is important to ensure that the water supplies to your taps and mixers are connected in accordance with the water
regulations (WRAS) requirements and good plumbing practice.
It is Wolseley’s recommendation and good plumbing practice that the supplies of hot and cold water to the products
should be equal (balanced) pressures in order to provide a consistent flow. Supplies should be from a common source.
Either mains or tank fed. If supplies are not equal pressures then non return valves should be fitted (not supplied).
There products have been designed to function on all types of water of water systems.
Please note: if a pump is to be installed to boost gravity supplies please refer to the pump manufactures instructions.
The hot and cold inlets for any of the products are hot on the left and cold on the right when viewed from the front of
the fitting. It is our recommendation and good plumbing practice that a service valve also should be installed up stream
in the inlet supply lines.
Pipe Connections
IMPORTANT. Before making any inlet pipe connections all supplies MUST be thoroughly flushed to remove any
debris.
Failure to do so could result in damage or low flow from the fitting.
It is a requirement of Byelaw 55 of the Water Fittings Byelaw Scheme that this function is undertaken before making
any pipe connections to supplies.
General Installation Notes
• Care must be taken during installation to prevent any risk of damage to the product or injury to installer.
• Installation must be carried out by a qualified and competent person and in accordance with the instructions supplied.
• Installations must comply with all Local and National Water Authority Regulations and Building/Plumbing
Regulations.
• Ensure that you have read and understood all sections of this manual before installation.
Water Supply Pressures
All fittings have been designed to function under the following conditions:
• Minimum supply pressure: 0.2 bar
• Maximum supply pressure: 5.0 bar
Generous flow rates are achieved at pressures as low as 0.2bar. At high pressures it maybe necessary to reduce
excessive flow rates by fitting stop or servicing valves in the supply line before the mixer or tap. These stop valves
facilitate ease of maintenance should it be necessary.
