Installation: FAQs
What are the design requirements for cold water storage cisterns?
All components making up and used within a cold water storage cistern must be of an appropriate quality and standard
If the water stored in a cistern has to remain wholesome all non-metallic materials in contact with water, including any surface where condensate forms, must conform with the current version of BS 6920 (or an equivalent).
Cisterns should be watertight and where appropriate lined or coated with suitable impermeable materials.
In addition to an inlet, outlet, overflow pipe and warning arrangement a cistern should have a rigid close fitting and securely fixed lid or cover. Cisterns, and their lids, should be made of materials which do not shatter or fragment when broken.
