Benefits

The CMP 25577-420-000 waterfall helps transform a pool or spa into a more relaxing, high-end outdoor environment. The 48" wide sheer descent creates movement, sound, and visual appeal that enhances both daytime and nighttime pool settings.

The back-port design allows installers to route plumbing from behind the waterfall, helping keep the installation clean and concealed. The 1" lip is useful for tight or clean-lined water feature walls where a longer lip is not required.

For pool builders and remodelers, this waterfall is a reliable choice for adding a premium feature without overly complex operation. When paired with the correct flow rate, plumbing, and wall setup, it creates a smooth, consistent sheet of water across the full opening.

Installation Notes

This waterfall should be installed by a qualified pool professional or experienced pool builder. Proper installation requires correct wall preparation, level placement, plumbing support, flow balancing, waterproofing, and finish integration.

For best performance, the waterfall must be installed level across the full width. Plumbing should be sized and balanced to provide even flow across the entire 48" opening. CMP performance references commonly use approximately 48 GPM for this 48" waterfall.

Before installation, verify that the back-port location, inlet spacing, and available wall depth match the project layout. Improper leveling, insufficient flow, uneven plumbing, or poor support can result in uneven sheet flow or water feature performance issues.
