Hi the flexi pipes are 19mm screw caps, I already have 15mm isolation valves fitted but need to reduce the stanadard 22mm to 19mm capsWhich part is 19mm?
Grohe typically are 3/8" female.
You would fit 15mm isolation valves then a small bit of pipe then a 15mm to 3/8" male iron
yes 22mm so your right its just a 22mm male connector to 10mm flex adapter just found 1 on screwfix. I will use the screw nuts from a couple of straight connectors I have spare to connect the small piece of copper pipe to 22mm male connector cheersI don't know what screw caps are.
The spec says G3/8" and I've done enough Grohe stuff to know thats what they normally are.
Is your pipe work 22mm?
Correct easy when you know the correct terminologyI think OP is talking about measurements in mm across the fitting - which we all know has nothing to do with what they are called in bsp or G as they get referred to nowadays.
I think you’re both talking about the same thing.
