erm,
bit embaarasing really, on a trv drayton lifestyle trv, its liquid filled and is contained in the head of the valve (plastic) part is it not?.
so changing the head on a suspect trv that is reaching max temp even when off or frost protection will sort it and not needing to drain down to change the body, am i right?. spent to long chucking them on new systems to remember. lol.
