PERFORMANCE CHARTS
These charts show actual system performance with friction loss factored in for various discharge pipe lengths.
Calculations and performance based on a system with 2" PVC, schedule 40 plastic pipe (C150), (4) 90º elbows,
(1) check valve and (1) shut-off valve. Wastewater requires a minimum scouring velocity of 21 gpm for 2" pipe.
Shaded areas do not provide min. scouring velocity - use only for gray water with no solids.
