Thanks. Here's what I'm working with. The water supply comes up from the bottom right (behind drywall), comes out of the wall, goes through a shut off valve and the pressure regulator (just below were picture cuts off), reenters the wall, turns left through a 2X4 and Ts. The up T is to the water heater, the down is the main cold water supply. Any advice on how to route the pipes for the softener?
