I'm adding new radiators in my new extension. I have lengths of 22mm plastic pipes under the floor linking exisiting copper manifolds. I plan to install the new radiators by inserting a 22mm Tee for flow and return and linking to a 22mm to 4 x 10mm Speedfit connector. I will use inserts throughout.
Is there any problem with keeping it in plastic to the radiator valve itself? The guy in Plumb Center recommended going back to 10mm copper pipe just before the radiator valve.
Any advice or recommendations welcome.
