Is a thermostatic radiator valve that has been left in the off
position likely to stay shut down despite the being wound full on?

I have a radiator which has not been used for a year and now will not
turn on, an it has been bled.

Take the top off and push the sprung pin in - does it move? If
not, tap it *gently* with a hammer. Does it move now?

On my Drayton valve (the one with a shiny chrome head) turning the valve off
pushes the pin in. Sometimes it gets stuck and to open it again I pull the pin
up with a pair of pliers

Agree. I used to regularly have to try both methods for my parents.

OK it's a Drayton trv 4, how do I get the top off? It doesn't come
with a pull.

Undo the knurled ring immediately below the white plastic body

Turn it anticlockwise as you look down from above.

The pin will be sticking up out of the centre of the valve base
underneath.

The pin will not move by a great deal - no more than 3-5mm

.... Place e.g. a spammer on top of the pin and tap that gently with a
hammer

I'd have thought they would be a bit soft for that.

Yeah, but it's got to be worth a try. If it didn't work you could
always try a bigger hammer. Might not free off the valve, but what the
hell...

If I could find a spammer I'd be very happy to oblige. Only I don't
think the idea of being "gentle" with a hammer would be part of the
exercise.....
