Herbie Question?

[mark]

As Todd said, you need two standpipes for a Herbie (primary and backup) as asking for flood without.

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).
