I am painting one of the bed rooms in my house. to get behind the radiator in the room I have removed it from the hot water pipe. I still have quite a bit of work to do on the room and don't anticipate being able to reattach the radiator for another couple of weeks. I would like to activate my heating system but can't while this radiator is not connected to the water pipe.
Is there a way that I can cap this water pipe for the time being while I finish painting the room? I would like to be able to heat the rest of my house during this time period.
