Dual Return Pumps

[Ubiq]

Setting up a Nuvo100 INT. Want to use 2 VarioS-2 for a turnover of between 3 and 5 per hour. Tank is drilled for one 3/4" return line, so 2 separate lines are no-go. I'm thinking 2 check valves on a y-connection are my only option, but will one 3/4" pipe have sufficient capacity to handle the upflow from two separate 3/4" lines at 792 (max rated) gph? Don't want to create a bottleneck.

Don't know the pump outlet size but it should NOT be restricted by a smaller pipe size.
Can you come back over the top twice?

I would run them on separate lines.
