Pit must be covered. It is usually 10-18’’ in diameter and 14-18’’ deep. See pump owner’s manual for pit size needed.
Install on a hard surface: brick, cement, or concrete block; no sand, clay, or gravel.
Unless otherwise noted:
Models with a tethered float switch require a sump pit at least 14’’ in diameter.
Models with a vertical float switch require a sump pit at least 10’’ in diameter.
