A:  I bought it for mop sink (water back flowed since my mop sink is in basement, so I bought it), but the water pressure required was too high for regular water flow. I fixed the issue by changing the screw inside to a longer one to reduce the pressure needed for the valve to open. I suppose you could do the same.
