So l learned with my water test my ReeFlo Suntail Gold is way to powerful for my system. I couldn’t even open the ball valve a 3rd of the way on the return without the emergency drain flowing hard. I contacted BSR where I bought the pump they recommended. I took there advice and changed my plumbing to help. I ran another 3/4 line directly from the return to the sump return section. And another 3/4 line to my refugium instead of using the drain line.
