The integrated landscape lid helps conceal the box within surrounding rockwork and planting areas, while the detachable weir allows the waterfall liner to be secured to the front of the unit.

Before You Order: Waterfall Box or Complete Kit?
This product is the individual 14" Cascade Falls Box, not a complete pond-less waterfall system.
To build a complete waterfall, you will also need a properly sized pump, water reservoir, liner, underlayment, connecting plumbing, and materials for constructing the waterfall and stream.
If you're starting a new project and prefer a coordinated package, consider our Elite Small 14" Cascading Falls Kit, which includes the major components needed for a complete pond-less waterfall installation.

Planning and Installing Your Cascade Falls Box
The Cascade Falls Box is installed near the top of a waterfall or stream. In a pond-less system, water is pumped from an underground reservoir to the box, flows down the waterfall, and returns to the concealed basin.
Our official installation manual provides the complete procedure. The following stages highlight the important planning and installation requirements.
1
Plan the Waterfall and Reservoir
Choose the waterfall location, stream layout, and underground basin configuration. Account for the dimensions of the Cascade Box, pump access, water supply, and electrical access. The reservoir must be sized for the complete system.
2
Prepare and Position the Box
Compact the supporting soil to help prevent settling. Keep the Cascade Box level from side to side, with a slight forward tilt of approximately one-quarter bubble on a level, as described in our installation guide.
3
Connect the Plumbing
The two factory-installed 2" spinweld connections provide installation flexibility. The water supply can enter from either side, with the unused connection plugged. A second feed line can also be used when the system is designed for it. Follow the manual for the required adapters and connection procedures.
4
Secure the Liner and Finish
Attach the waterfall liner to the front of the box using the specified silicone, detachable weir, and screws. Test the system for proper water flow and leaks before finishing the surrounding rockwork and landscaping.
Installation Tip: Keep Water Moving Toward the Spillway
Correct positioning helps prevent water from collecting unevenly inside the box. Our installation instructions specify a level side-to-side position with a slight forward tilt.
Keep the waterfall liner properly secured and ensure the surrounding stonework directs water back into the lined stream and reservoir.
Compare Blue Thumb Waterfall Boxes and Spillways
Choosing the correct waterfall width and flow capacity is important when designing a stream. Our Cascade Falls Boxes are available in several sizes, and we also offer lower-profile spillways and smaller DIY waterfall boxes.
Use this comparison to identify the product that fits your waterfall design. Each model has different dimensions and plumbing requirements.

|---|---|---|---|
| DIY Mini Cascade PB1359 | 10" | 1,800 GPH | Two 1" fittings |
| DIY 20" Cascade PB1762 | 20" | 2,500 GPH | Two 1.5" fittings |

Maintenance and Seasonal Care
Keeping the diffuser mat clean and maintaining adequate reservoir water levels helps the waterfall operate as intended.
Routine Maintenance
- Remove leaves, sediment, and other debris that may interfere with water flow.
- Inspect the Matala diffuser mat and clean accumulated debris as needed.
- Our maintenance guide recommends removing and cleaning the waterfall box filter media at least annually.
- When possible, rinse the diffuser using water from the existing system rather than chlorinated tap water.
- Monitor reservoir water levels and check the pump and plumbing connections regularly.
Winter and Spring Care
- Follow the appropriate winterization procedure for your pump and complete pond-less system.
- If operating during freezing conditions, monitor for ice dams, restricted flow, and changes in reservoir water level.
- During spring startup, remove winter debris and inspect the box, plumbing, liner, and diffuser.
- Check that the Cascade Box remains level side to side and maintains its slight forward tilt.
- Follow our seasonal maintenance guide before restarting the waterfall.

Frequently Asked Questions
Does the 14" Elite Cascade Falls Box include a pump and reservoir?
No. PB1106 is the individual waterfall box. A pump, underground reservoir, liner, underlayment, and the other major components required for a complete pond-less waterfall must be purchased separately. If you need a coordinated system, we also offer a complete 14" Elite Cascading Falls Kit.
How do I know what size pump to use?
The 14" Cascade Falls Box has a maximum flow rating of 2,500 GPH. Pump selection should account for the desired waterfall appearance, vertical lift, plumbing length, and friction loss. The actual flow delivered to the waterfall box must remain within its rated capacity. Our Sales/Tech Team can help you evaluate your system.
Can I connect plumbing from either side of the Cascade Falls Box?
Yes. The box has two factory-installed 2" spinweld connections. Our installation guide explains how to connect the water supply to either side and plug the unused connection. The second connection may also be used for an additional pump line when the system is designed accordingly.
Can multiple Cascade Falls Boxes be installed together?
Yes. Our Elite Cascade Falls Boxes can be installed side by side for wider waterfall designs. Each box must receive appropriate water flow, and the overall plumbing and reservoir system must be sized for the complete installation.
How can I hide the waterfall box in my landscape?
The attached landscape lid is designed to help conceal the box. Surrounding rockwork, gravel, mulch, or suitable plantings can be incorporated into the finished design. Maintain access where needed for inspection and diffuser maintenance.
How do I clean or replace the Matala diffuser mat?
Periodically inspect the diffuser for accumulated debris. Our maintenance guide recommends removing and cleaning the waterfall box filter media at least once per year. Replacement black Matala diffuser media is available for the 14" Cascade Falls Box under item MT14BK.
What warranty comes with the 14" Elite Cascade Falls Box?
Our Blue Thumb engineered-plastic Cascade Falls Box is covered by a lifetime manufacturer's warranty against manufacturing defects for the original purchaser. Proper installation is required, and modifications after purchase void the warranty. Labor and freight are not covered. Refer to our official warranty document for complete terms.
