Recirculation Line

Hello all

I have moved my existing HW tank and need to extend and re-hook up my 1/2" recirculation line. The pump will be located at the new tank location. This location happens to be between the two most remote supplies (Master Bath and Kitchen). I have attached a file showing two different options for extending the recirculation line (Option A and Option B).

I'm looking for advice if there is a preference between the options shown, or if there is a better way that I have not yet explored. thanks

OF the two, "B" is the better option because you MUST have balancing valves to controll the flow from the two directions. The only way to install them and have them accessible is to bring the lines from the two directions back to the tank and then install the valves before merging them into the pump.
