Pro-Series Large Just-A-Falls Kit w/ High Strength Res-Cubes 50" Spillway (18' Stream)

Pro-Series pondless waterfall kit 50 inch spillway 18 foot stream brings a professional-grade pondless waterfall build within reach by bundling the core components needed for a clean, natural-looking installation.

Designed around a wide spillway and an underground reservoir, this kit helps you create the sight and sound of moving water without maintaining an exposed pond. The reservoir cube system is built to hold significant water volume while staying hidden beneath decorative stone, supporting consistent circulation and reliable pump access through the included pump vault.

What’s included

• Spillway: 50" Vianti Falls stainless steel spillway for a smooth, sheet-style flow over rockwork
• Reservoir system: High-strength reservoir cube system to form a stable, high-capacity underground basin
• Service access: Pump vault with intake assembly to simplify maintenance and protect the pump area
• Plumbing: Flexible PVC components plus check valve and fittings to complete the main run

How it works

Water is pulled from the concealed basin, delivered to the spillway at the top of the stream, and then returns through the rock and gravel streambed back into the reservoir. With the Pro-Series pondless waterfall kit 50 inch spillway 18 foot stream, you can shape the stream up to the intended length, contour the channel for natural movement, and dial in flow to match your landscape style.

Installation overview (high level)

• Excavate the reservoir basin and stream channel; set elevations for a steady grade.
• Install underlayment and liner; place reservoir cubes and pump vault.
• Level and set the spillway at the stream head; connect plumbing and fittings.
• Backfill, dress with gravel/boulders, and test flow before final detailing.

Pump note: Pump selection is typically based on desired flow rate and total dynamic head; pump is sold separately. For best results, confirm plumbing layout and head height before choosing a pump.

For contractors and serious DIY builds alike, the Pro-Series pondless waterfall kit 50 inch spillway 18 foot stream is a streamlined way to achieve a polished, low-maintenance water feature that looks custom-built.
