Thanks guys 
 
niloc16: 
As Mark mentioned the CL pump will be below the main floor so I don't expect much noise. Fingers crossed. 
 
Mark: 
I think Im going to shoot for 1000 GPH from my sump return pump & 3000 GPH from CL. I may go a little larger and just hold them back a little with a valve.  
 
As mentioned below I think ill go with ... 
Closed Loop 
Sequence 4000SEQ19 / 4000 GPH at 0 head & 3000 GPH at 10 ft of head 
Sump Return Pump 
Velocity T4 / S4 1446 GPH at 0 head & 1000 GPH at 10 ft of head. 
 
What do you think of these pump brands?
