UK water regulations and EN1717 require the prevention of backflow or back siphonage of contaminated fluids into the drinking water supply.
The greatest risk are fluids found in WCs and bidets, hospital wetrooms and kitchen sinks, which are classed as fluid category 5. The risk posed by class 5 fluids means mechanical hydraulic protection devices are not permitted, and only physical air gaps are accepted.
Our innovative solution is a shower hose retainer which physically ensures an adequate air gap at all times, and once fitted can only be removed by destruction. The hose retainer must be positioned in the shower configuration in such a way that the shower handspray can never reach the contaminated fluids.
Retainers which allow the hose to pass through them by simply unscrewing it are now only suitable for fluids up to category 3.
