Poster #14,
So you are denying that there is accumulated sludge? What do you think the black stuff is?

The TRV fell off
- Thread starter Mr. Clueless
- Start date
So how do you think the sludge you say is in the system got to travel to the outside of it? If sludge had been able to get through the o-ring seal around the TRV needle, then large amounts of water would have come out as well. There's just been a small seepage of water around the needle which as caused some rust to form there.
Because of that seepage, ideally the complete TRV should be replaced, but if the OP doesn't want to do that, replacing the TRV head with a new one will probably suffice, though then they'll always be a risk of a larger leakage from this valve.

Hell fire I didn't expect this.
Have we ever had a power flush? Yes. Can't remember when though. I'll say maybe 6 years ago?
Just to double check, the plumber was clanging & banging all the radiators. Sound like a power flush? After all this job he then installed a Magnaclean filter.
I did wonder about the corrosion in the first phot as to whether that's normal or not.
I don't know of any noticeable leak on that TRV although there are one or two rads which have that green crud around them which I think it supposed to be leakage? Again not massively so. I'll have a see tomorrow & come back here.
Regards the unscrewing as mentioned here, is it just a case of get an adjustable spanner & undo or what?
Reason I ask is when you scroll around videos & come across plumbing videos, the comments are always full of contradicting do this, don't do that & nobody agreeing on how it should be done.
Bit like this post here I suppose.
Am I supposed to hold the lower part tight while undoing that collar or should it be fine to just remove as I said with a pair of adjustables?

Not adjustables as they don’t have the required grip. Water pump pliers, mole grips or similar
OP,
Where are the signs of rust on the pin - there is a little green corrosion.
The tiny weeping leak will carry particles of sludge, & when the tiny amount of water evaporates it will leave the particles, these particles will accumulate over time.into the black sludgy stuff seen in the pic.
As my earlier post - best practice says replace the whole valve.
Perhaps you will pic any other crusty suspects plus the ones you mention?
Six years with a possibly unwashed filter, a failed TRV, & green crud at the rads suggests that the system might need professional attention.
