4" is better! Will it ever drain a pond in a HURRY!

Jim

Not likely the bottom drain is hooked to a three barrel filter on the
same waterline as the pond, with the pump in the third barrel and the
pump is 1800 gph. It can only pump the barrels half empty except the
last one, so the pump would only remove half the water in the pond.
