The Waterway 310-1880 Executive 1.5 HP Wet End Assembly is a complete replacement wet end designed for spa and small-pool pumps that use a 48-frame, 1.5 HP motor. It features 2″ male-buttress threaded inlet and outlet ports for side-discharge, making it compatible with standard 2″ pump plumbing. This wet end includes the volute housing, cover, impeller, wear ring, shaft seal, suction cover, drain plug, O-rings, and hardware — offering a full ready-to-install unit to restore hydraulic performance when your old wet end is cracked, leaking, or worn. The 48-frame design supports both single- and dual-speed motors, giving flexibility for spa or small-pool applications.
