Default Radiator blanking plugs?

In an earlier contribution to this discussion,

Do they exist? I have a rad off to decorate, and the thermo valve
has just opened & dumped the system contents into the room/garage.

Can I get a screw on cap anywhere to blank off hte open end of the
valve, or is there another way to stop it opening?


TIA

As others have said, the TRV should have been supplied with a 'decorators
cap' which screws on, once you've removed the thermostatic head, and holds
the pin firmly down. If you don't use that there is a danger - as you appear
to have discovered - that if the temperature drops sufficiently the valve
will open, even on its lowest setting, and cause a flood.

If all else fails, find something (e.g. one or two 5p pieces) which you can
sandwich between the valve and the head, to make sure that the pin stays
down under all circumstances.

Alternatively . . .
Do your radiator tails have the equivalent of a compression joint where they
connect to the valves? If so, you could make up blanking-off devices with
the following ingredients for each one: Short length of 15mm copper pipe,
15mm olive, compression nut, 15mm stop end.
