Materials and standards

Every water fitting must be installed, connected, altered, repaired or disconnected in a workmanlike manner. This means that all work must be carried out in a professional manner and to one of the standards required by the regulations, they should either:

o    Conform to an appropriate British Standard or some other European Economic Agreement state specification which provides an equivalent level of protection and performance; or

o    Conform to a specification approved by the regulator; or

o    Conform to a method of installation approved by Cambridge Water within its area of supply.

Anyone who proposes to install any water fittings must ensure that they follow and comply with the requirements of Schedule 2 of the Regulations, Government and Water Industry published guidance.

Information for plumbers

Plumbing systems must be properly designed, installed and maintained to meet the requirements of the regulations. This is to protect water quality, to ensure safety, ease of access for maintenance, detection of leakage, protection against damage from freezing and other causes and the prevention of contamination by pipes fitting and by backflow.

Where water or water-using equipment is used with fluids or materials which could contaminate it, there must be adequate protection to stop backflow of potential contaminated water into other parts of the system, especially the drinking water.

The regulations define fluid categories according to the type of risk that contaminants may pose.

The regulations specify the appropriate type of backflow prevention device that must be fitted to guard against backflow where these substances may be present. The Fluid Risk Categories are detailed in Schedule 1 of the regulations.

If you are employing someone else to install the plumbing, consider using an Approved Plumber or Contractor who will guarantee compliance of the new installation.
