The right sump pump for your home depends on your basement’s average water inflow, the height water must be pumped to discharge, and whether you need backup protection. Most Spokane-area homes do well with a 1/3 to 1/2 horsepower primary pump plus a battery-backup unit. For very high water tables, a dual-pump system with separate floats is the safest bet.
Sizing factors
