Recirculation Pump

[Meaford Maples]

I am in the process of rebuilding my RO to add a second 4x40 post. I will be upgrading the pump to a Procon 330 with a 1.5 HP motor. Since I already have a Procon 265 gph pump, I was wondering if there was any value to installing in on the recirculation line to increase flow.
Thanks
