I'm about to take out a stud wall between my kitchen and a utility room as we're extending kitchen and fitting a new suite. There's a small rad on one side of the wall so this will be coming out too. The sub floor is solid concrete so all the pipe work runs through the walls. The missus has plans for a conservatory or an extension in the next few years, so I was thinking of terminating the pipes back at the main wall. I could then hide them behind a kitchen cabinet and use them to feed a new rad in the conservatory in the future. My concern is dead legs/no flow and it could be for several years. If i had a wooden sub floor i'd have probably followed them back to the tee and capped them here. I dont fancy chasing these pipes and knocking chunks out of walls around the house. Any thoughts or suggestions would be appreciated.
