I'm making a closed loop with a Quiet One 9000. it's rated at 2300 gph max. I will have several return lines from the pump. What size/ how many drain lines should i use. the input is 1 1/2" and so is the return. They seem like pretty sweet little pumps. I hope the question is clear enough.
Hmm, don't know if this will help, but here's how I ran my closed loop:
Started witha ReefloDart, has a 2" intake and a 1.5" outflow. My closed-loop has 2 1" bulkheads for outflow, and 2 1" bulkheads for return. I ran 1" flexible braided vinyl hose from both intake bulkheads into barbed fittings that mounted to a 2' PVC T-fitting. This went into a 2" section of pipe, then to the pump. I have in-line shutoffs in the Vinyl, and a union before the pump. This same set-up is done for the returns. I.e., a small section of PVC pipe, a union, then a tee and hose barb fittings to the vinyl.
Make sure to use shut-offs and unions for emergencies, repairs and upgrades in the future. Obviously the entire thing can be done in PVC, I just chose the vinyl for ease of installation. If you do use vinyl, DEFINITELY used the braided stuff, its far stronger and more durable.
