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 Pegler Yorkshires recommendation and good plumbing practice that the supplies of hot and
cold water to the products should be at 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 single check valves must be fitted (supplied).
The installation of any thermostatic product must comply with the requirements of the Water Supply
(Water Fittings) Regulations 1999.
Regulation G15.14
G15.14
Submerged inlets to baths or washbasins in any house or domestic situation are considered to be a
fluid category 3 risk; they should be supplied with water from a supply or distributing pipe through
a double check valve. Submerged inlets to baths or washbasins in other than a house or domestic
situation, and sinks in any location, are considered to be a fluid category 5 risk and appropriate
backflow protection is required for this level of risk.
The shower head of any shower hose pipe should be fitted by a fixed or sliding attachment so that
it can only be discharged at a point not less that 25mm above the spill-over level of the bath tray or
fixed appliance. (Shower kit not supplied)
This product has been designed to function on all types 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 (Pegler PB300) should be installed upstream 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 Bath and Shower
Mixer. It is a requirement of Schedule 2, 13 of the Water Supply (Water Fittings) Regulations 1999
that this function is undertaken before it is first used.
The Thermostatic Bath and Shower Mixer inlet connections are threaded ¾" BSP
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.
• Please ensure that you have read and understood all sections of this manual before
installation.
Water Supply Pressures
This fitting has been designed to function under the following conditions:
• Minimum supply pressure 0.2 bar
• Maximum dynamic supply pressure 3.0 bar
• Recommended dynamic Pressure 1.5 – 2.0 bar
Generous flow rates are achieved at pressures as low as 0.2 bar. At high pressures it may be
necessary to reduce excessive flow rates by fitting a pressure reducing valve in the
supply line before the fitting. Using the supplied flow regulator in the outlet of the
product will assist its performance also, but will not negate the need for the Pressure
Reducing Valve!
