The Regulatory background
In July 1999, the Water Supply (Water Fittings) Regulations 1999 replaced local water byelaws in England and Wales. They were made under section 74 of the Water Industry Act 1991 to prevent the waste, misuse, undue consumption, contamination or erroneous measurement of drinking water.
The Regulations set minimum standards for the water consumption of WCs, which account for around 30% of household water consumption, as well as washing machines, dishwashers and washer driers. They also contain requirements to ensure the durability and leak tightness of water fittings and guidance on minimising the length of pipe runs to reduce the run-off necessary to get hot or cold water at the tap. The Regulations reduced the maximum flush volume of new WCs to 6 litres and permitted more efficient dual flush systems.
