Thanks for your reply i was afraid of that.
Yeah all was turned off no heat and no pump on, the problem with it is the pipework only shows by about a inc and half so not enogh to freeze.
Could anyone tell me if i need to drain an open vented system to replace a radiator valve?
I tried freezing the pipes but with no luck as the amount of pipe i'm able to get to coming from the floor is not enough. :cry:
