in fact I've knocked it a couple of times and provoked a squirt of

Wait until the room cools down a bit and the valve opens properly.

Thermosatic valves are supplied with a maintenace cap. You remove the
thermosatic head and screw the cap down in its place this closes the
valve properly.

For a permenant fix you need to properly cap the pipes. Compression
stop ends would be the easiest by reusing the nut and olive from the
old valves. Best would be soldered stop ends.


If you're quick, and I was once, you can remove the radiator valve by
undoing the nut while firmly pushing the valve onto the pipe, then
whipping off the valve with thumb ready to cover the pipe. Use a
reverse operation to place the compression cap on the end of the pipe.
If you're luck and quick you'll lose surprisingly little water.
