New water efficient WCs

The Water Fittings Regulations make a number of significant phased changes to WC suites.

From 1 January 2001

	Mandatory reduction in flush volume to six litres for all newly installed WC suites.
	Introduction of a high performance specification to cover the entire WC suite, to include endurance testing for the siphonic and non-siphonic mechanisms and improved tests for the effectiveness of the flush. The specification will ensure that sanitaryware continues to satisfy consumer expectations while also improving its water efficiency.
	Dual flush cisterns permitted for any mechanism and suite passing the performance specification.
	Existing WC flushing devices can be replaced with non-siphonic devices; provided the unit flushes the same volume as the cistern already in use.
	Integral WC cistern overflows are now permitted, which allows the overflow to run into the WC pan, therefore requiring no external pipework.
