Sorry Michael, I didn't see you post until now. I tested everything in the garage and had to make several tweaks as I went. What is the purpose of heating and smashing the pvc? How does that provide more flow? Actually I had to much flow from the return so I've got the ball valves dialed down a bit. I'm using a mag 7 (700 gph) and the pump is only 12 inches below the outlet in the top container. I am also in the process of adding a spray bar at the other end.
