A few of the TRV valves I fitted 21 years ago have started to leak - looks like the plastic nut (?) etc at the top has gone brittle and is starting to disintegrate. Oddly some others fitted at the same time are OK, but probably worth swapping now too.
Anyway, are there any recommendations for a quality TRV body, perhaps with brass parts not plastic? With a 10mm pipe fitting, not 15mm.
