Radiator Valves?
Can someone explain to me how to replace my radiator valves..is there any soldering involved or is it a matter of remove and replace (not THAT simple i know).
I know my pipe size is 15mm but im not sure about the valves themsleves, the rads are quite old. how do i determine the valve size too?
At the moment i have very old TRV's on there which i know dont work for a start,i want to replace them with standard none TRV's...any recomendations on which valves to get?
Thank you
