The Waterway 310-1130SD Side Discharge Spa Wet End is a replacement volute housing designed for compatible spa pump systems using a “C” style impeller. Engineered for side discharge orientation, this wet end channels water from the impeller into the plumbing discharge, supporting circulation and hydrotherapy performance. Built for durability in chemically treated, high-moisture spa environments, it restores hydraulic flow performance in pump rebuilds and repair applications.

Product Overview

The Waterway 310-1130SD Side Discharge Spa Wet End serves as the primary housing component in compatible spa pump systems that use a “C” style impeller. Positioned around the impeller, the volute captures the accelerated water and directs it laterally through the discharge port, supporting circulation through spa jets, heaters, and filtration paths. Side discharge orientation is often used where equipment pad layout or cabinet design requires lateral plumbing connections.

Manufactured for long-term performance in high-moisture and chemically treated environments, this wet end housing resists internal pressure, vibration, and continuous exposure to sanitizers and balancing agents. Proper installation with the correct “C” style impeller and compatible shaft seal ensures efficient hydraulic performance and helps restore reliable pump operation during maintenance or rebuild procedures.
