Hi! Lots of pump and hydrodynamic questions here for someone smarter than me.
I’ve zeroed in on a Jebao return pump. I know. I know. But I’ve done the work and think this is a good decision.
I’d like to plumb one + a second that will take over in an emergency. Ie: if return_flow=0 for > 10 mins then pump_1 off, pump_2 on. Programming TBD. That’s a later post.
How do I plumb this? I have 10’ of head height to get by and I’d like my return to do double duty on the refugium and main display. I could plumb in both pumps with check valves right after the pump but check valves are a no-no in this hobby (for most).
I could use 1.5” solenoids on both pumps but that’s a spicy price.
What am I missing here?
