Natural Wonders® 18″ Waterfall with Bottom Port (25576cmp18bmp)
The CMP Natural Wonders® 18" Waterfall with Bottom Port delivers an impressive cascade with underside plumbing for standard wall installations. Select from White or Gray and four lip sizes for a custom fit.
Flush-Mount 18″ Waterfall with Convenient Bottom Port Plumbing
The CMP Natural Wonders® 18″ Waterfall with Bottom Port combines the generous 18-inch cascade width with an underside plumbing connection for maximum installation flexibility. This bottom port configuration is the go-to choice when your pool wall does not have rear access for plumbing, allowing the water supply to connect from directly below the waterfall body. The result is an unbroken 18-inch water curtain that transforms your pool edge into a serene water feature.
Key Features
- Bottom port plumbing simplifies installation on standard pool walls and deck-level applications
- 18-inch wide water sheet offers a noticeable visual upgrade over smaller 12″ models
- Variable flow adjustment ranges from a whisper-quiet sheet to a vigorous cascade
- Four lip sizes (1″, 6″, 9″, 12″) let you match the waterfall to your specific edge geometry
- White and Gray color options pair well with popular pool plaster and tile finishes
Design Considerations
When planning your 18-inch waterfall installation, consider the pump flow rate required to maintain a full, unbroken water sheet across the entire width. CMP recommends consulting your pool builder to ensure adequate flow. The bottom port connection uses a standard 1.5-inch slip fitting, compatible with most residential pool plumbing systems. This waterfall can also be paired with CMP LED lighting accessories to add color-changing illumination to your water feature at night.
