Choose the PB16KIT for a wider water curtain and a one-foot longer maximum stream at the same price. How the Elite Small Cascading Falls System Works The PB1229 creates a pondless (disappearing) waterfall: water flows over the 14" Elite Spillway and into an in-ground basin hidden entirely below gravel and stone. The reservoir is invisible — only the flowing waterfall is visible in the finished installation. Excavation & liner: Dig a basin sized for the two Small Basin Matrix boxes and Mini Pump Canyon. Lay the protective underliner, then the 10’×15’ PondGard EPDM liner over the top. Reservoir: Place the two Small Basin Matrix boxes on the liner. These modular boxes create the underground water storage volume. Fill the surrounding space with washed gravel to conceal the system. Pump vault: The ClearWater 2,340 GPH pump sits inside the Mini Elite Pump Canyon® on the liner, submerged and protected. Access the pump through the Canyon lid for maintenance without disturbing stone. Plumbing: The pump discharge assembly (with check valve) connects to the 1.5"×25’ Black Flex PVC pipe, which runs up the slope to the 14" Elite Spillway Box at the top of the waterfall. Spillway: Water enters the Elite Spillway Box and is distributed evenly by the internal baffle, producing a smooth water curtain across the full 14" lip. Recirculation: Water flows down the rock streambed and re-enters the buried liner basin to repeat the cycle. Maximum supported stream: 5’ long × 1’–2’ wide.

Just add stone and water. What are the benefits of the Elite Series vault and spillway? The 14" Elite Cascade Spillway Box and Elite Pump Canyon® (Mini) are both manufactured in the USA by Blue Thumb and carry Lifetime Warranties. The spillway features reinforced construction and structural ribbing that allows you to stack heavy landscape rocks and boulders directly on the unit to conceal it completely in your waterfall design. The internal baffle distributes incoming pump water evenly across the full 14" width, producing a consistent, glass-like water curtain without surging or uneven flow. The Elite Pump Canyon vault is reinforced to resist ground pressure when buried and provides a dedicated pump access lid that allows you to remove or service the ClearWater pump without disturbing surrounding stone. Both the spillway and Pump Canyon are backed by Blue Thumb's Lifetime Warranty. Note: the included ClearWater pump (#PB1045) carries an 18-month warranty separate from the Elite component warranties. Why are Blue Thumb Basin Matrix boxes better than traditional gravel basins? The two Small Blue Thumb Basin Matrix boxes included in the PB1229 create a modular underground reservoir that holds significantly more water per cubic foot than a gravel-only basin. Traditional gravel basins require large excavation volumes to store enough water to keep the pump submerged through evaporation cycles. Basin Matrix boxes provide structured void space for water storage while their rigid construction supports the weight of decorative stone and gravel placed above. Key advantages over gravel-only basins: less excavation required for equivalent water storage; more reliable pump submersion; easier to configure and install; the rigid structure prevents basin collapse under stone weight. The Mini Pump Canyon vault sits alongside the Basin Matrix boxes on the liner, forming the complete underground reservoir system. Is the 45-mil EPDM liner durable enough for heavy rocks? Yes. The included PondGard liner by Firestone is a 45-mil EPDM rubber liner rated to remain flexible at temperatures as low as −40°F. It is UV-resistant, ozone-resistant, and certified fish-safe. The 45-mil thickness is the industry standard for professional pondless waterfall installations and is significantly more durable than PVC alternatives. Installed over the included protective underliner (non-woven geotextile fabric), the PondGard liner creates a puncture-resistant, leak-proof foundation for the basin. The underliner prevents sharp rocks or roots beneath the excavation from contacting the liner directly. Together, the two-layer system provides a professional-grade waterproof barrier sized at 10’×15’ for the PB1229 basin configuration. How much maintenance does this waterfall kit require? The PB1229 is a pondless system -- maintenance is minimal compared to a traditional pond: Water level: Top up the basin periodically as evaporation reduces the level. The ClearWater pump must remain submerged to operate correctly -- running dry shortens pump life. Spillway: Occasionally clear debris from the 14" spillway lip to maintain an even water curtain. Pump access: Access the ClearWater pump through the Mini Pump Canyon lid to check the intake screen for debris without disturbing surrounding stone. Water treatment: Use the included Muck Buster tablets to prevent organic buildup in the basin matrix. Winter: In freezing climates, remove the ClearWater pump from the Pump Canyon and store it submerged in a frost-free location. The liner, Basin Matrix boxes, and Pump Canyon can remain in the ground year-round.
