Aquascape 77000 Waterfall Spillway 22 Inch 7500 Gph

Product Description

The AQUASCAPE 77000 is a 22-inch waterfall spillway designed to deliver a broad, even sheet of water in pond and water feature installations. Rated for a maximum flow of 7,500 gallons per hour (GPH), it is built to handle high-volume recirculation systems where visual impact and water movement are the primary design goals. Pond contractors, water feature installers, and experienced DIY pond builders typically specify this spillway as the primary discharge point in pondless waterfall and formal pond systems.

This spillway suits residential and light commercial water feature projects where a wide, dramatic water curtain is desired. Its 22-inch weir width produces a sheet effect across the full opening at optimal flow rates, making it a common choice for stacked-stone waterfall walls, raised formal ponds, and pondless reservoir systems. It is installed at the head of a waterfall run, fed by a submersible or external pond pump sized to the GPH rating and total head pressure of the system.

Key Features

• 22-inch wide weir opening produces a broad, even water curtain
• Maximum rated flow of 7,500 GPH supports high-capacity pump systems
• Designed as the primary discharge point in waterfall and pondless water feature builds
• Sized for both residential and light commercial water feature installations
• Compatible with standard pond plumbing fittings used in recirculating water feature systems

Compatibility

Designed as an OEM-style component for use in recirculating pond, pondless waterfall, and water feature systems requiring a wide-weir spillway discharge outlet.

Installation Notes

Installation is typically performed by pond contractors or experienced water feature installers following manufacturer guidelines. Before making any plumbing connections, shut down and disconnect the recirculating pump. The spillway must be leveled precisely during installation to ensure an even water sheet across the full 22-inch weir width — even minor off-level mounting will cause water to favor one side of the opening. Inlet plumbing should be sized and sealed to handle the full rated flow without backpressure leaks.
