What sump pit size configurations are listed?

Explanation:
Sump pit sizing is about fitting the pump or pumps and their piping with enough clearance inside the pit. When you have a single pump (simplex), a 24-inch diameter pit provides the needed space for the pump and float assembly plus the inlet and outlet connections. If you have two pumps (duplex), you need more room to accommodate both pumps, their wiring, float switches, and piping, so a 30-inch diameter pit is used. That 6-inch difference ensures there’s room to service each pump and to keep the piping arranged without crowding. The listed configuration matches this standard pairing: simplex pit at 24 inches and duplex pit at 30 inches. Other pairings either don’t reflect this common sizing approach or wouldn’t reliably leave enough clearance for two pumps and their components.
