Whenever you alter or replace pipework in the home, ensure you only use approved plumbing materials and an approved plumber.
It is essential that any work carried out on domestic plumbing does not result in deterioration in water quality. The Water Supply (Water Fittings) Regulations 1999 and the Water Industry Act 1991 detail the responsibilities of water companies, customers and people who install water fittings and work on plumbing systems.
We strongly recommend that you use an approved plumber who will be able to ensure that the work complies with the Water Supply (Water Fittings) Regulations 1999. Anglian Water has an approved plumber scheme known as Aplus.
When making any changes to plumbing in the home, always follow the manufacturers instructions carefully and ensure pipework is laid appropriately and that any undue warming is avoided. Ensure that header and other storage tanks have adequate covers, vents and ventilation.
The Water Regulations Advisory Scheme (WRAS) provide interpretation of the Water Supply (Water Fittings) Regulations 1999, along with advice on subjects such as backflow prevention, installation of fittings, and prevention of cross-contamination and so on.
