Mini Just-A-Falls Kit 3' Stream

Mini Just-A-Falls 3' stream waterfall kit is a compact, turnkey option for adding the sight and sound of moving water in tight landscape areas. Designed around a short run and a small recirculating reservoir, it helps streamline planning by bundling matched components that work together as a complete system.

Instead of sourcing parts one-by-one, this kit focuses on the core build elements that typically determine reliability and ease of installation. A 45 mil rubber liner and protective underlayment help form a watertight basin and channel, while a 12" waterfall spillway is intended to produce a clean, consistent sheet of water. The pump vault and pump outlet assembly support stable pump placement plus more convenient access for service. Two modular reservoir cubes provide below-grade water storage for recirculation, helping keep the feature compact while still functional.

What’s included

• Liner + underlayment: 45 mil rubber liner with matching underlayment
• Waterfall spillway: 12" spillway to shape the cascade
• Water management: pump vault, pump outlet assembly, and two reservoir cubes
• Plumbing items: flexible PVC pipe and PVC glue
• Pump: 1850 GPH direct drive pump

Installation notes for best results

• Dry-fit first: mock up the stream path and spillway placement before setting final stone.
• Plan access: confirm power availability and allow room to reach the pump vault later.
• Finish materials: select boulders, gravel, and decorative stone to match your landscape style.

Whether you’re building new or refreshing an existing small feature, the Mini Just-A-Falls 3' stream waterfall kit helps reduce guesswork with a straightforward component set. If your goal is a tidy, natural-looking cascade with minimal footprint, the Mini Just-A-Falls 3' stream waterfall kit provides the essential structure so you can focus on stone placement and final detailing.

FAQ

Is this suitable for a small backyard or patio corner? Yes—this style of compact system is commonly chosen for tighter spaces that still benefit from real moving water.

Do I need additional rocks or decorative stone? Most installations still require site materials such as boulders, gravel, and finishing stone, selected to fit the look you want.

Can flow be adjusted? Many waterfalls can be tuned through plumbing layout or optional controls; use an approach compatible with your build and pump setup.
