Plumbing Info

*Same rules apply to other household products like washing machine, fridges with water connection and any water filter or appliance connected to a water tap.
Handsprays
Handsprays shall be installed in accordance with The National Construction Code – Volume Three and where used as a douche spray are classified as High Hazard and appropriate additional backflow prevention will be required.
For use as a bidet spray, a RPZD that complies with
