Did you know all premises that have a water supply from Welsh Water are legally required to ensure their plumbing systems comply with The Water Supply (Water Fittings) Regulations 1999? Essentially, everything on a customer’s side of the boundary is required to comply.

If you don’t know what is covered by the regulations, then you can find a diagram explaining them below. While Welsh Water owns and fixes the section on the far left of the diagram, the Regulations apply to the two sections on the right: your private supply pipework and your internal pipework and fittings.
