Build a beautiful sheet waterfall directly into a retaining wall with our Medium Formal Falls® Kit with Light. This complete recirculating water-feature system combines a 28-inch stainless steel spillway, a concealed 42-gallon basin, a 4,200 GPH pump, and a color-changing LED light with remote control. Enjoy the movement and sound of a pond-less waterfall during the day and an illuminated display after dark.
The stainless steel spillway fits within the wall structure, producing a broad sheet of water that returns to the concealed basin below. The full-top spillway design supports stacked wall materials, while removable basin access covers make pump servicing possible without dismantling the feature.
The included LED fixture is positioned in the basin to illuminate the falling water. Use the infrared remote to control the lighting and create a distinctive evening display. The light is not built into the stainless spillway itself.
We've assembled the essential operating components for the waterfall system. Wall construction, decorative finishing materials, site preparation, and electrical service are supplied separately.
Our Medium Formal Falls® stainless steel weir (PB1793) features two 1-inch female-threaded inlets and a sealed top designed to support stacked wall materials.
Our Small–Medium Formal Falls® Basin (PB1632) includes an anti-splash mat, dual pump-access covers, and connection locations for an optional automatic water-fill valve.
The included Clear Water Pump (PB1052) is paired with a BodyGuard prefilter sock, pump discharge assembly, flexible hose, PVC primer and cement, connection fittings, and installation hardware.
The linked pump page offers multiple sizes. This kit uses the 4,200 GPH model.
One basin-mounted color-changing LED light and infrared remote are included with PB1656L. Point the remote toward the light when operating it. This lighting package distinguishes the kit from the non-lighted Medium Formal Falls® configuration.
Prefer the same waterfall without LED lighting? See our Medium Formal Falls® Kit without Light (PB1656).
4,200 GPH is the pump's maximum rated flow. Actual delivered flow depends on plumbing, elevation, fittings, and installation conditions.
Our Small and Medium Formal Falls® kits share the 42-gallon basin. The Large Formal Falls® uses a larger reservoir for its wider stainless steel spillway.

This system is intended for a built-in wall installation. The basin may be positioned in-ground or above ground, depending on the design. Plan the wall structure, basin footprint, plumbing route, water landing area, pump access, and suitable power connections before beginning construction.
Establish a suitable level foundation for the basin and wall. Confirm the layout and leave enough clearance for servicing the equipment.
Place the basin against the wall and select the plumbing connection side. Cap the unused connection as directed in the installation manual.
Place the pump inside the prefilter sock, assemble the discharge plumbing, and connect the two spillway inlets using the supplied fittings.
Complete the wall and decorative finish. Leave the direct water-impact area above the anti-splash mat clear of gravel. Fill the basin before operating the pump, then test the water flow and lighting.
Check the basin water level regularly and replace water lost through evaporation or splash. Periodically inspect the pump prefilter, remove debris from the basin, and clean the spillway opening if the water sheet begins to separate.
The stainless steel spillway is designed to drain when the system is shut down. However, where prolonged freezing occurs, our installation manual recommends removing the pump and storing it in a bucket of water in a location that will not freeze. The basin does not need to be drained for winter storage.
After spring thaw, our manual recommends removing the old basin water, refilling with clean water, reinstalling the pump, and restarting the waterfall.
The basin includes connection locations for an optional automatic water-fill valve to help maintain the reservoir water level. Because application guidance varies between Blue Thumb water-fill systems, confirm the correct valve with our Sales/Tech Team before ordering.
Review our Fountain Basin Auto Fill Kit. If the selected valve requires a 30 PSI maximum supply pressure, a separate 30 PSI Regulator is required when incoming pressure exceeds that limit.
Different components in this kit carry different warranty periods under our published Blue Thumb warranty:
All warranty coverage is subject to the applicable terms, installation requirements, and exclusions. The entire kit does not carry a single lifetime warranty.
Use these official resources for complete assembly instructions, dimensions, and professional installation planning.
The 28-inch stainless weir CAD drawing refers to the non-lighted spillway because the LED fixture in this kit is installed in the basin rather than inside the stainless weir.

Our Sales/Tech Team can help you review wall dimensions, waterfall height, basin placement, lighting, plumbing, and optional automatic water-fill equipment before ordering.
It includes the primary operating components: stainless steel spillway, basin, pump, prefilter sock, plumbing materials, and one color-changing LED light with remote. Wall materials, decorative stone, suitable electrical service, and site preparation are separate.
No. This is a recirculating pond-less waterfall system. Water collects in the concealed basin and is pumped back to the stainless steel spillway.
The supplied color-changing lighting system is operated with an infrared remote. Point the remote toward the light to select the available lighting settings. Refer to the supplied controller instructions for its exact functions.
We recommend a maximum 24-inch drop measured from the basin top to the spillway. Taller installations may increase splash and wind-related water loss. Contact our Sales/Tech Team before planning a nonstandard height.
Yes. The Formal Falls® basin can be installed in-ground or above ground as the project design allows. Provide adequate support, concealment, and access for future servicing.
No. This Formal Falls® kit is intended for freshwater applications and must not be used in saltwater systems. Ask our Sales/Tech Team before planning an installation near a pool or chemically treated water source.
The stainless steel spillway self-drains, and the basin does not require winter draining. In areas with prolonged freezing, our installation manual recommends removing the pump and storing it in water in a location that will not freeze.
No. The lifetime limited warranty applies to the qualifying engineered-plastic basin. The Clear Water pump has an 18-month limited warranty, while the stainless steel water feature and RGB LED light have their own one-year limited warranties. Consult our official warranty PDF for complete terms.
