Guide to Building a Wall Waterfall

wall watefallWall Maint Guide to  CTA feather 06









Each Formal Falls requires a particular flow rate to achieve the level of performance detailed by the illustrations and guide. 

Please note, for custom applications where the Formal Falls will be used outside of the standard kits, you will need to provide accurate information pertaining to the install to your supplier. 

This product is not intended for harsh environments, such as saltwater or other corrosive environments, please refer to our Custom Formal Falls.

Overall heights desired, proximity of the pump to the Formal Falls, and plumbing schematics covering all connections and sizing between the pump and the Formal Falls unit.  Providing detailed drawings and specifications will ensure proper performance resulting in ideal flow rates through the Formal Falls.

Watch for competitor flaws:

Two main reasons a waterfall will begin to separate when flowing are: 

1.  Waterfall spillway is clogging

2.  Waterfall spillway is compressed

The 1/8" opening of the Formal Falls and the design of the internal baffle keep our units from allowing debris to back up inside the opening.  One way to quickly notice the difference in our opening is by how noticeable the thickness of the water becomes and how strong the flow is moving away from the wall.

The stainless steel of a Formal Falls keeps the integrity of the opening intact when under heavy downward pressure, therefore preventing the "saber-tooth" look of the waterfall being shown above.  

Project Ideas:

Although Formal Falls can be purchased as a self-circulating kit, below are a few other ways to use the Formal Falls:

1.  Swimming Pool Waterfalls

2.  Mid-wall installs vs. under copping

3.  Waterwalls- downward facing

4.  Indoor Waterfalls built in-wall

5.  Specialty: Boat & Outdoor Showers

Custom Basin Specs:

Each size Formal Falls has it's limitations depending on installation specifications.  For falls heights greater than 22" high, we recommend a Custom Basin Package.  Select from the sizes below:

For Retaining Wall Waterfalls

Made in the USA, Formal Falls are a beautiful yet simple way to add the aesthetics of water to your surroundings is to build a retaining wall waterfall.   The water flows out from the stone in a nice, smooth sheet and into a basin below.  These wall waterfalls can be easily added to any block wall structure and are a great alternative to fountains.  They can be used to adorn a garden, pool, outdoor living area, or even a home or business foyer!

The FormalFalls has a low-energy, color-changing, remote controlled, LED lighting system that creates a beautiful nighttime display. The basin was designed to create an easy way to install the system within a block wall structure, and the use of the autofill kit virtually eliminates all maintenance for the consumer.

Formal Falls Basin

Formal Falls Basins can be sunk in-ground or used above grade
NO Winterizing needed.  In the spring simply drain and add fresh water.  The basin come equipped with dual pump access (left or right side) through a stainless steel access panel located just under the splash mat.  Additionally, if you are looking to install our Elite AutoFill Valve to maintain the water level or to reduce manual filling, a pre-installed spinweld located on both the left and right makes installation fast and easy.
