My current line coming into the house is 1/2" copper. From there it goes into old 1/2" steel pipe. I am adding a new bathroom and am going to take out as much of the old piping as possible as well as add a manifold so i can easily shut off certain fixutres.
If i go with 1/2" pex would i be okay? or should i go with 3/4" since i heard 1/2" inside diameter is smaller than 1/2" copper is.
