About this wet end

The LX WUA400 is a replacement wet end (pump housing and impeller side) for 4HP, 56-frame LX spa and hot tub pumps, including Intertek-compatible setups, with 2" × 2" connections. Replacing the wet end restores flow and fixes leaks when the motor itself is still running well. It's a direct OEM replacement for part WUA400.

Before you order: Match all three: 4HP, 56-frame motor and 2" × 2" plumbing. Always check your motor's frame size and plumbing layout before ordering.
