One cool rad ?

[joesoap13]

Usually yes 1/2" bspt.

Thanks terry,
I would like to just get it blinking for now, will change rad as well later, it,s an old rad but have two others same, but working.
Changed two in march.

Just undo the nuts and swap valve usually. (After draining)

No problem, that's plumbing for you!

As above should be a standard fitting but we could confirm if you can upload a photo.

As the other two have. Same trv,s on would be best to replace them at same time whilst system is drained.
Have had trouble with them.
One rad is 3 metres long ! And papered up to it.
Will try and upload a pic, not familiar with it.
Cheers.

Cheers Terry.
Thanks again for reply, much appreciated.
Looking at that old trv, in the pic,and new ones I had fitted to new rads in kitchen in March, it looks as if it’s deeper to the olive, so may have to cut a bit of pipe from olive to end of pipe going in to the Trv so it makes contact with the existing olive ?
Have had to do this in the past I think !
Unless I can get a trv that’s as deep as existing one so it makes contact with the olive.
Could do with taking it off and going to Screwfix with it see if they are all standard depth now.
Do you know.
It’s an old westherm.
Can you see the difference ?
The other two are different, one is the same, and the other is a shallower one.
C H system in this house is a Heinz 57 mix.
All sorts of pipes, rads,fittings, even imperial pipe underfloor.
Doing one job nearly always leads to another, that’s why ,if it’s working ,I leave it, but not for long, cannot, it bugs me.

Update.
seems it was not the tr v after all

fitted a new one, same problem.no flow.
the inlet pipe from circs to tr v was blocked with crud!
been trying to unblock it all afternoon.
I think it,s the chrome but which comes through the floor to trv ?
Flowing a bit better, not sure how much flow I should get when it,s the only rad on, and boiler running ?I
Keep turning rad on/off to force crap out into bucket,and repressurising.
Hundreds of times so far !
Do it again tomorrow and see the result.
Whole floor has to come up to replace pipe,coopper/plastic,and plastic joints.
Hope not
Would it pay to put cleaner in system and flush through ?I
Any type recommended please?
Then inhibitor,got fernox.
