3.1.1 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 fitted 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 flow through at one time is limited to a pre-determined maximum,
providing the flow rate through it exceeds 2 litres per minute.
• The Water Block also incorporates a non-return valve.
3.1.2 Specification
3.1.3 Precautions
• The Water Block will help to contain leakage exceeding a rate of 2 L/min.
• Note
The leakage at lower flow rates may not be detected by the Water Block and could remain
unchecked.
• Appropriate measures should be taken to contain leakage in these circumstances.

Section 3.1 Water Block description
(optional accessory)
The HydroTap has an internal leak detection system
that will automatically shut off water supply into the
product, should a leak occur internally. For external
leaks that cannot be protected by the HydroTap, consider using a Water Block.
For UK, the Water Block is a recommended installation requirement.
