Herbie Question?

[Kabong]

I got it.
So Technically it would probably work, But I'd just be begging for a flood without a back up pipe.

It's not that bulkheads flow less, just flow is balanced to return pump. Skimmin has Herbies, 2-1.5" drains, and flows ~2000gph so not like bulkheads running less (but must be closed to max'd for gravity).

According to the RC drain size calc you need a minimum 1.85" for 2000GPH Giving a difference of 1.15" So it's got a fair bit of spare.

Any one else running a Herbie setup could you give your drain size + your Aprox flow.
