Gravity System
Cold Mains & Gravity Hot Supplies
If the cold supply to the shower is direct from the cold water mains and the hot water supply is
gravity fed from the cold water cistern via the hot water cistern you MUST fit a pressure
reducing valve or a 6 l/min flow regulator.
Site Preparation
It is important to plan the installation thoroughly to suit site conditions before
commencing.
• Before commencing the installation ensure site conditions are suitable.
• The shower mixing valve is designed for concealed pipework, whether in a solid or studded
wall with the supply pipes coming from below, above, the side or through the wall.
• The thickness of wall tiles, plaster or plaster board should all be considered when routing the
hot and cold supply pipes.
• The valve requires the supply pipes and wall brackets to have 150mm centres and sufficient
copper pipe must protrude from the finished tiled surface to allow a water tight compression
joint to be made.
• Ensure the shower valve will be horizontal when installed.
• The supply pipes if not embedded into the wall with plaster the should be fixed securely
to the studding.
• The whole system should be thoroughly flushed, prior to the connection of the hot and cold
water supplies to the bath-shower mixing valve, to remove any debris that may be in the
supply pipework.
• Ensure there are no joint leaks before finishing the wall.
• Isolation valves must be fitted in an accessible position to both the hot and cold supplies
should the valve need to be isolated in the future for servicing.
