I have bought 5 Drayton trv4 15mm angled valves off eBay and planned to fit them today.
I have drained the system and taken off an old valve. The Drayton TRV4 fits on the copper pipe but has a smaller thread where it attaches to the radiator.
I guess I have brought the wrong valve but I’m hoping I haven’t?
