Is there any way to repair a leak around the pin on these TRV's or is it a new valve I need? I was preparing to replace it but read somewhere that a pin leak can be repaired under pressure and without even having to drain the system - although, maybe I read it wrong.
Also, does anyone know how to balance the system using these TRV's? There are numbers (0-6 I think) when I take the head off. Is it better to balance using the lockshield valves or the TRV's?
Thanks in advance.
