A suitable water supply should be chosen depending on the application. There are several types that can be used, a mains water supply (mains pressure only; or mains with booster pump) or stored water supply (pump supplied from a water tank; regulated pressurised vessel or gravity fed water system).

For residential buildings over 4 storeys or 18m high a fire sprinkler system must be installed.

All valves on a system designed BS 9251 (except category 1) that control the flow of water to a system should be electrically monitored for the correct open position.

It is mandatory for systems designed to BS 9251 all flow-switches installed on a system are tested annually to determine they are functioning as designed. Zonecheck Residential can carry out this test automatically, saving 100% of the water.
