now that I think about about it I might have a sump pump kicking around somewhere. I know it needs a new impeller I might try that before I get one of those
Frank I haven't looked at the gph actually, it's a 1/2HP pump. But I gravity drain the tank cause I gravel vac every wc and the pump is too powerful for my gravel vac. To refill I use the pump. The head height is about 13'
You actually answered my real question ... suction coming from the pump for gravel vac. I need something a tad more powerful than my python but not enough to drain my tank in an instance. 1/2 HP would be way too strong.
