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 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.
