POLL: How Much Return Line Flow Do You Run?

[elFloyd]

660 gph monitored with apex at the two drains into the sump. 180 gallon tank. Vectra L1 running wide open. Pump also feeds UV (250 gph), carbon reactor (100 gph) and GFO (80 gph). 1” pvc lines... could have gotten more flow using 1 1/4” or 1 1/2” lines.

75 gal DT with 40B sump returns are two 3/4 pipe ,running off a Vectra M1 at about 70% I'm thinking that's about 1400 gph
