I need to run a new branch water line for a refrigerator. Existing 1/8" copper tubing takes off with a piercing clamp from a 3/4" pipe in the ceiling above a cabinet, to an in-line filter in the back of the cabinet, then runs laterally through an adjoining cabinet containing the built-in oven to the refrigerator space, then down the wall to the fridge.
HO is having new cabinets installed and does not want tubing running through the cabinets.
I am considering cutting out a short section of the 3/4" copper line in the ceiling at the point where it is pierced and installing a reducing tee over the wall top plate. From there I would run 1/2" copper through the top plate of the wall down to about 12" above the floor and then laterally through 3 or 4 stud bays to a recessed box behind the fridge.
Can I get 1/2" copper through the studs or do I need to use soft copper tubing?
The ceiling joists run perpendicular the wall. If I wanted to run the lateral through the joists, would that be easier than through the walls?
