Please can someone advise me or offer me some help possibly - i am trying to close off the valves to 1 radiator, to give it a flush through with a hose outside. it seems sludged up and has a cold middle/sides. i have shut the lockshield side ok but the other side has a thermostatic valve and i believe these do not shut fully off. i unfortunately do not have the cap to shut the pin down fully. is there anything i can do to make sure it shuts off the flow of water fully as i don't want a flood on my carpet!

remove the head put a 5p coin underneath and replace the head a lot of them do shut off altogether btw 
they useally fully shut.
shut them both fully and open the bleed valve if it stops you know they are both closed.

Hi
Thankyou all for replying and helping me. I have tried the 5p trick and the head would not go fully on again after - it was too tight a fit!
So most trvs do fully shut off then - mine doesn't go down to 0 setting though - just a star sign (frost setting is that)??
Is there anything else i can do to make sure the valve doesn't open when the rad is off??

did you open the valve fully first then put it on then close it against the 5p ?
if your only going to flush the rad and replace it just put it on the frost setting
if its staying off any lengh of time cap the outlet

I will try the frost setting - maybe if i keep all the doors shut then the temperature will stay high enough so the trv won't open?
capping off is a good idea - how exactly would this be done easily? if easy (i have some fittings in a box in my shed) i will do this and then i can relax and take my time flushing!

Just get a 1/2" brass cap and a bit of PTFE tape. Wrap the tape round the threads and screw on cap.
a 15mm compression stop end won't fit.
you need a 1/2" cap end to screw on the end of the trv.

should be ok on frost setting we're not due for frost in essex yet. LOL.
