A Herbie standpipe potentially could flow more in that it's a siphon but then to create the Herbie you're restricting the flow with a valve to have the water back up over the top of the stand pipe.
Would think for estimating probably not to far off with the commonly used gravity flow rates (~600gph for the 1"). |
