The Water Supply (Water Fittings) Regulations 1999 set out the installation requirements for plumbing systems, in the same way building regulations set out the requirements for buildings.
There has been a long history in regulating plumbing systems in homes and businesses in the UK designed to protect public health by safeguarding drinking water through the use of water companies’ Water Supply Byelaws.
More recently the Government carried out a review and introduced the Water Supply (Water Fittings) Regulations 1999, to prevent inefficient use of water, the waste, misuse, undue consumption, erroneous measurement of it and, most importantly, to prevent contamination of drinking water supplies.
The Water Regulations Advisory Service (WRAS) provide national guidance on the regulations for water companies and their customers. Water Undertakers are responsible for the enforcement of the regulations within their water supply areas.
