Another failed TRV

[Radio Fixer]

You have obviously got the knack Jeffery.  I know you can easily replace the valve bodies but is there any point?  One knock and it doesnt have to be hard and it needs another one.  If I were to replace them it would be with something else (maybe Pegler as you went for) hence then water messing about with.

So just use them as manual valves and forget it
