Jimec3,

Sounds like you understand my question. The thing I am wondering about is how I would hook up the valve on the return side. Normally (on the supply side), the valve is hooked up so one output is fed by two inputs (depending on position of the valve).

My question is, can a three port valve be hooked up so you have one input and two outputs (where the outputs are controlled by the position of the switch)? And if so, how do you hook it up.

Maybe I am over-thinking this as I am assuming the valves only allow fluid flow in one direction (fluid in through the input port and out through the output ports). If the valves allow flow in any direction, then hooking it up would just be the reverse of how the supply lines are hooked up to the valve.
