Here is the diagram of the place in the basement where I will be connecting the pipes (here only the cold pipe). PEX Pipe from mains was clamped up to point A in the diagram, under a joist that borders basement staircase. That pipe (that extends as much as 6ft or so beyond point A) needs to be connected to a coper pipe going to the second floor and to another PEX going to the first floor (kitchen). The latter are around point B in the diagram. I am not worrying about hot water at this point. In that 5ft space between the two joists I need to connect the pipes and I want to put one shut off to shut off things on the second floor, not on the first (since this is next to basement staircase, I can just turn it off/on from the staircase).. What is the most elegant, efficient, catering appropriately for both the first and the second floors?An error occurred submitting the question.
