Q; This pump is a powerful thing. Cleared out a large basement with a foot of water in just a couple hours. It doesn't pump flush to the surface. Are there pumps which will pump lower, even at a lower rate?
A: Floor sucker or ground low level pumps like the 5MSP, LSC1.4S, LSR2.4S, PXL-65011. Keep in mind that the impeller in the pump needs to be wet in order to pump and that determines the low level point.
