Hi Guys, need a bit of advice please.
I have two old rads that are not getting hot, barely warm.
I flushed one ages ago, Black,no change.
I suspected crud, but just drained the other one, and the water is crystal clear, could drink it!
Was going to flush it, but didn’t bother .
Can I just change the body of the trv, using the existing nuts on rad and pipe,as the trv gets hot, but not beyond it!
That seems the obvious problem, even though the pin is ok, springs back.
Means draining system.!
Theirs inhibitor in the system.
