Finishing buying the materials for the 200gal wetdry sump for my 1500gal pond. Its above the pond and drains into it. Anyway I need to know if 3 of these 3" connectors (see link) Will be enough to drain aprox 9500gph via gravity. I have read that 3" flows 16,000gph via gravity but I just want to double check.
