The importance of correctly plumbing the water tank warning pipe and overflow correctly
Warning pipes and overflows that are not plumbed correctly can lead to thousands of euro worth of water damage to buildings. Failure to plumb the warning pipe to a monitored area may lead to faults going undetected for long periods.
How it works
The role of the warning pipe is to alert personnel of rising water levels in the water storage tank, indicating a fault or malfunction with the inlet or other connections.
If undetected, water levels will continue to rise and exit the tank through the water tank overflow. It is vital that the overflow is correctly piped to a gully or bunded area to accommodate overflow water and avoid flooding, water damage, and possible costly repairs.
WRAS warning pipe and overflow guidelines
‘Warning pipe’ means an overflow pipe with its inlet located in the cistern at such a height that it will start to flow before the main overflow operates and with its outlet located in a position where the discharge of water can be readily seen.
Wherever possible warning pipes should discharge outside a building, however where this is not practicable owing to the design of the building, they may be discharged internally provided the discharge is conspicuous. View the WRAS regulation guide for examples of acceptable arrangements for the discharge of the warning/overflow pipe.
