The Waterway 310-1440 wet end is designed for compatible 4.0 HP Executive spa pump applications and features 2-1/2 inch MBT by 2 inch MBT connections in a 56-frame configuration. A part like this is useful because it restores the entire hydraulic side of the pump while keeping the larger 56-frame fit and mixed connection layout used by the original design.

High-output spa pumps benefit from accurately matched wet ends because frame size and plumbing format are closely tied to installation success. This Waterway assembly is a practical replacement when the original 4.0 HP Executive wet side needs a more complete renewal than a small-parts repair can provide.

For compatible 4.0 HP Executive spa pump repairs, this Waterway wet end is a practical replacement when the complete 56-frame wet-side assembly with 2-1/2 inch MBT by 2 inch MBT connections needs renewal.
