Great question. I'm actually thinking about this also. So I will b following.
Frankie I am in Logan if you want to stop by and see how I plumb the same reactor. Below is what I used in order from the pump.
From the pump:
Union
PVC
Gate Valve
PVC
T
From T to the reactor:
3/4 slip reducer with 1/2 FPT
1/2 MPT quick connect adaptor )(You need to buy this it does not come with the reactor)
Line to reactor
From T to return:
PVC
Check Valve
PVC
Gate Valve
Plumb to display
