Have removed an old rad in one of my rooms, so now have two pipes side by
side coming out of the floor. What do I need to close these off, as
although I don't need the heating - can't repressurise it anyway, I still
need the hot water from the combi boiler. If I turn on a tap, the water
runs hot, but as soon as I turn it off, water comes out of the top of these
pipes. Surely I can close these off until I'm ready to install the new rad,
I'm just not sure what I need to purchase.
