I am planning the fitting of a new bathroom in our home. It isn't a straight replacement so I will need to renew the piping to the fittings.
When I remove the bathroom I will strip the pipes back to the 22mm hot and cold stop valves and start fresh. From there I will be using JG Fast fit plastic piping and fittings.
The cold will be mains fed, The Hot is pumped gravity fed. In a few months we will be moving to a mains combi boiler for the hot which should balance the pressure.
When re-plumbing the bathroom I was going to use non return valves on the hot supply to prevent the cold water surging down the hotpipe
My questions are:
1) Would I need non return valves on the cold supply as well?
2) Would I need to fit non return valves before each mixer (Bath / Shower / Basin) or could I fix one to the supply before it branches?
3) When we move both supplies to mains pressure should I remove the valves?
Thanks
Dan.
