How to choose between them

Step up to 1/2 HP or more when the pump runs often in storms, the water table is high, or the discharge rises more than about 10 ft. In a small pit a large pump cycles quickly, so check the basin with the cycle calculator.

Maximum flow is at zero lift and maximum head is where flow stops; at your real lift a pump moves less than either number suggests.
