Aquascape 77023 Waterfall Spillway 12 in 4000 Gph

Product Description

The AQUASCAPE 77023 is a 12-inch waterfall spillway designed to create a smooth, consistent water curtain in pond and water feature installations. Built for flow rates up to 4,000 gallons per hour (GPH), it connects to a pump or plumbing manifold and discharges water evenly across its full 12-inch lip. Water feature installers and pond contractors use this spillway to achieve a uniform sheet-flow effect without the turbulence or uneven distribution common with improvised overflow edges. The wide discharge opening makes it well suited to decorative waterfalls, pondless waterfall systems, and formal water features.

This spillway fits into residential and light commercial water feature builds where a clean, polished waterfall effect is required. It is typically mounted into a vault, reservoir, or basin wall with the discharge lip positioned at the desired waterfall height. Pond and water feature contractors install it alongside submersible or external pumps sized to meet the rated flow capacity. It is appropriate for both new construction and retrofit applications where an existing overflow needs to be replaced with a purpose-built spillway unit.

Key Features

• 12-inch wide discharge lip delivers a full, even water curtain across the entire opening
• Rated for up to 4,000 GPH maximum flow, accommodating a range of pump capacities
• Purpose-built spillway geometry reduces turbulence and promotes uniform sheet flow
• Designed for straightforward integration into pond vaults, basins, and reservoir walls
• Suitable for both new water feature installations and retrofit replacements

Compatibility

Designed as an OEM-style component for residential and light commercial pond and water feature systems requiring a 12-inch spillway with flow capacity up to 4,000 GPH.

Installation Notes

Installation is typically performed by pond contractors or experienced water feature technicians. Shut down and disconnect all pumps before fitting or adjusting the spillway. Ensure the mounting surface is level to maintain an even water curtain across the full 12-inch lip. Follow local plumbing codes and the pump manufacturer guidelines when sizing supply lines and fittings to the spillway inlet.
