How do you size a sump pump?
Multiply the number of inches that the water rose in a minute by 60, in order to estimate the volume of water that would come into your pit during an hour of steady rain. Multiply this number by a “safety factor” of 1.5 to figure out the pumping capacity you need.
Do I need a 1/3 or 1/2 HP sump pump?
The average home with an above average water table, will most likely require a 1/2 HP sump pump. This sized sump pumps about 35 to 40 percent more water than 1/3 HP sump pumps do. If water is higher than usual, a 1/3 HP can handle a higher vertical lift when discharging water.

A 1/3 horsepower (hp) pump is satisfactory for most houses, but a 1/2 hp pump doesn’t cost that much more.
How high should water level be in sump pit?
The water should not be that high in the sump. It should be down to around the 2-3″ level inside.
Does sump pump need vent hole?
