Bathing equipment in a nursing or care environment is considered to be a fluid category 5 risk. The supplies to all taps and showers outlets must be protected by a suitable form of fluid category 5 backflow protection.
In practice this means being supplied from storage incorporating an adequate air gap (such as a Type AB air gap)
Or by maintaining a gap between a tap and shower outlet and spill over level of 20 mm or twice the diameter of the supply pipe (whichever is the greater) measured as shown below.
Please note this gap, must also be maintained between any shower handsets and the spill over level of toilets and bidets.
