In addition to the specific guidance given in this chapter there are some general requirements of the water fittings regulations, byelaws in Scotland which apply.
All components making up and used within a cold water storage cistern must be of an appropriate quality and standard . Any non-metallic component or material in direct contact with the water must conform to BS 6920 or its equivalent.
In many cases the local water undertaker will need to be given advanced notice of the proposed installation of any cold water cistern. This is an important simple and essential check to minimise the risk to water supplies.
Although the water in the cistern is intended to remain wholesome as a condition of consent it is likely the local water supplier will require backflow protection to be installed. This is typically achieved by suitable air gap arrangement, in some circumstances a double check valve may also be required.
