Backflow prevention

Thanks mike. Running over it in my head, just confusing myself in the end.

Just want to make sure I've got no comebacks. Cover myself before anything.

could you not ring local building inspector and tell him what you are planing to do and ask for help ?

Building inspector won't have a scooby. The water inspector from the local water undertaking is the person that you need to speak to for this sort of thing.

same thing applies with showers that can reach toilet pan. you must create an air gap. a shower screen as a barrier or a fixing on the hose/riser bar.
