What are the minimum sump dimensions?

Explanation:
Sump pits need enough interior space to let the pump operate reliably, give room for the float switch to move, and store a minimum amount of wastewater between pump cycles. The dimensions given for the minimum configuration—16 inches across the top, 14 inches across the base, and 22 inches deep—provide a practical minimum volume (roughly 2.25 cubic feet, about 17 gallons). That amount of space helps prevent the pump from short cycling and gives access for installation, service, and piping. Larger dimensions would add capacity but aren’t necessary to meet the minimum requirement.
