Section 5 Water block installation
5.1 Description
• The Water Block is designed to be installed upstream of any Zip product and associated pipe-work
to minimise the potential for water leakage in the event of a system malfunction.
• The Water Block is ideal for limiting potential leakage and resulting water damage from water
heaters, water chillers etc. when tted in supply pipe work that is subject to mains water pressure.
• Once set, the Water Block will ensure that the volume of water that can ow through at one time is
limited to a pre-determined maximum, providing the ow rate through it exceeds 2 litres per minute.
• The Water Block also incorporates a non-return valve.
• The Water Block is WRAS approved.
5.2 Specication
5.3 Precautions
• The Water Block will help to contain leakage exceeding a rate of 2 l/min.
• Note The leakage at lower ow rates may not be detected by the Water Block and could remain
unchecked.
• Appropriate measures should be taken to contain leakage in these circumstances.
