DRAYTON TRV4 THERMOSTATIC RADIATOR VALVE - leaking

[bartolr]

I Hvae a very small leak from one of the DRAYTON TRV4 THERMOSTATIC RADIATOR VALVES in our house. Can anyone tell me how to fix it rather than having to replace the whole unit?

Thanks,

R

Never seen a valve body leaking. Complain to Drayton!

Only seen one leak- and it happened to be in my own bedroom. 'Is it leaking up the spindle?' That's what the Drayton guy said to me at Phex. It was, so although its very rare, I guess they know about it. Tiny weep made the head seize. Head cleaned up and re-usable but valve duff.
