The kit ships complete with the TT4000 TidalWave3 Asynchronous Pump (4,490 GPH, 230W, 3-year warranty), 10-foot flexible PVC pipe, AF1000 AutoFill valve, 36" splash mat, and all installation hardware. Lifetime basin warranty. 3-year pump warranty. What does "36"" mean in this kit name? The "36"" refers to the spillway width this basin system is designed to support -- all Atlantic 36" formal spillways (36" Colorfalls, 36" Scuppers, 36" WaterWalls). The basin itself is 56"W × 24"D × 16"H -- significantly wider than 36" to provide adequate water volume and pump access beneath the spillway. The spillway (sold separately) mounts above the basin; water flows over the spillway lip and into the basin below, where the TT4000 pump recirculates it back up to the spillway. 42-Gallon Basin | 56"W × 24"D × 16"H TT4000 TidalWave3 Pump -- 4,490 GPH | 3-Yr Warranty AF1000 AutoFill Valve Included For All 36" Formal Spillways (Colorfalls, Scuppers, WaterWalls) Lifetime Basin Warranty Model: CFBASINKIT36 | Atlantic Item: 73851 | SKU: 00582 What's Included Basin System CFBASIN36 basin -- 56"W × 24"D × 16"H; 42 gal; one-piece construction; integrated pre-filtered pump chamber; built-in plumbing channels; can be installed above or below grade; Lifetime warranty 36" Splash Mat -- minimizes splash loss and keeps debris out of pump chamber Double filter mats -- keep debris out of the pump chamber, minimizing cleanouts Pump & AutoFill TT4000 TidalWave3 Asynchronous Pump -- 4,490 GPH max | 230W | 115V | 2.0A | 20' max head | 20' power cord | 1.5" inlet/outlet | compact 9.25"L×6"W×7"H | 3-year warranty AF1000 AutoFill Valve -- automatically maintains water level to prevent pump starvation due to evaporation Complete Installation Kit 1-1/2" × 10' Flexible PVC pipe Pump discharge fitting Adjustment/flow valve PVC spray glue PVC cleaner Thread sealant Fittings and hardware Installation instructions Not Included -- Sold Separately 36" Formal Spillway (Atlantic 36" Colorfalls, 36" Stainless Steel Scupper, or 36" WaterWall -- choose your spillway style) Lighting for Colorfalls (optional -- Atlantic Color Changing Colorfalls may include LED) Additional PVC pipe if run length exceeds 10' Technical Specifications Specification Detail SKU / Model 00582 | CFBASINKIT36 | Atlantic Item 73851 Basin Dimensions 56"W × 24"D × 16"H (supports 36" formal spillways) Basin Capacity 42 gallons Basin Construction One-piece; integrated pre-filtered pump chamber; built-in plumbing channels; above or below grade Pump TT4000 TidalWave3 -- 4,490 GPH | 230W | 115V | 20' cord | 3-year warranty Pump Max Head 20 ft Pump Connections 1.5" MIPT inlet / 1.5" FIPT outlet PVC Pipe 1-1/2" × 10' flexible PVC (included) AutoFill AF1000 AutoFill valve (included) Splash Mat 36" (included) Compatible Spillways All Atlantic 36" Formal Spillways: 36" Colorfalls, 36" Stainless Steel Scuppers, 36" WaterWalls Basin Warranty Lifetime Pump Warranty 3 years (TT4000) How the Atlantic Formal Spillway System Works The CFBASINKIT36 basin sits below or at grade level, serving as the water reservoir for the entire system. The 36" formal spillway (Colorfalls, Scupper, or WaterWall -- sold separately) is mounted on a retaining wall or hardscape feature above the basin. The TT4000 TidalWave3 pump, housed in the basin's integrated pre-filtered pump chamber, draws water from the 42-gallon reservoir and pushes it up through the 10-foot flexible PVC pipe to the spillway above. Water sheets evenly across the full 36" width of the spillway and falls into the basin below, completing the recirculating circuit. The AF1000 AutoFill valve automatically replenishes water lost to evaporation, keeping the basin at the correct level without manual monitoring. The double filter mats in the pump chamber trap debris before it reaches the TT4000 pump, extending maintenance intervals. The splash mat across the basin grate minimizes water loss from splash, which is particularly important in windy locations or when the spillway height creates a significant drop. The basin can be installed above or below grade: below-grade (buried in a retaining wall base) creates a clean, concealed look where only the spillway is visible; above-grade installation surrounded by garden block allows for a more accessible installation in patios and hardscape settings. Atlantic notes that the basin dimensions work seamlessly with standard 4" garden block construction. TT4000 TidalWave3 Pump -- Asynchronous Efficiency The included TT4000 TidalWave3 Asynchronous Pump (4,490 GPH max, 230W) uses Atlantic's asynchronous motor technology, which combines magnetic induction efficiency with direct-drive flow geometry. Compared to traditional mag-drive pumps, the TT-Series moves significantly more water per watt -- reducing operating costs for a system designed to run continuously year-round. The compact 9.25"L × 6"W × 7"H pump body fits within the basin's integrated pump chamber. Clog-resistant design and hard-water tolerance make this pump particularly well-suited for formal spillway applications where the pump runs at full output continuously.

Which spillways are compatible with this basin kit? The CFBASINKIT36 is designed for all Atlantic 36" formal spillways, including: Atlantic 36" Colorfalls (White LED or Color-Changing LED) -- the most popular pairing Atlantic 36" Stainless Steel Scuppers -- for contemporary/modern water walls Atlantic 36" WaterWalls -- for dramatic waterfall walls The basin is specifically sized to receive the full flow of a 36" spillway, with the 56" wide basin footprint ensuring all water is captured and recirculated. The 42-gallon capacity and TT4000's 4,490 GPH output are matched to produce the correct sheet flow across a 36" wide spillway lip. How does the TT4000 Pump perform in this system? The TT4000 TidalWave3 is Atlantic's premium asynchronous pump, producing up to 4,490 GPH at maximum flow using only 230 watts. The asynchronous motor design moves significantly more water per watt than traditional mag-drive pumps, making it well-suited for a formal spillway system that runs continuously. Full TT4000 specifications: 4,490 GPH | 230W | 115V | 2.0A | 1.5" MIPT inlet / 1.5" FIPT outlet | 20' maximum head | 20' power cord | 9.25"L×6"W×7"H | clog-resistant open-faced vortex impeller | 3-year warranty. In a typical 36" formal spillway installation, the TT4000 lifts water through 10-15 feet of head (depending on wall height), delivering a full, even sheer curtain across the 36" spillway. The flow adjustment valve included in the kit allows the flow to be reduced for a thinner, more elegant sheer descent effect. Can the Atlantic 36" Basin be built into a retaining wall? Yes -- this is the primary use case. The 56"W×24"D×16"H basin is designed for seamless integration with standard 4" garden block construction. Install the basin at the base of the retaining wall; the wall blocks are built around the basin; the 36" formal spillway mounts at the top of the wall and water falls into the basin below. The basin can be installed above or below grade: Below grade (buried): Basin installed in excavated area; only the spillway visible above; cleanest visual result Above grade (elevated): Basin sits at surface level surrounded by block; accessible for maintenance; works on existing patios How does the AF1000 AutoFill valve maintain the water level? The included AF1000 AutoFill Valve connects to a standard garden hose or outdoor water supply line and maintains the basin at the correct water level automatically. As evaporation reduces the water level, the float-operated AF1000 opens and adds water until the level is restored, then closes. This is essential for a formal spillway system: if the water level drops too far, the TT4000 pump draws air instead of water, causing cavitation and premature pump failure. With the AF1000 installed, the system is effectively self-maintaining -- no manual water top-ups needed. This is particularly important for commercial installations or vacation properties where the system may run unattended for extended periods. What maintenance is required for the splash mat? The 36" Splash Mat sits across the basin opening and serves two purposes: it minimizes water loss from splash (water droplets land on the mat and drain back into the basin rather than being lost to the surrounding landscape) and it acts as a pre-filter, catching leaves and debris before they enter the pump chamber. Maintenance is minimal: periodically remove the splash mat and rinse it with a garden hose to clear accumulated debris. In areas with heavy leaf fall, rinse weekly during autumn. In cleaner environments, monthly maintenance is typically sufficient. The double filter mats in the pump chamber further protect the TT4000 pump from fine debris that passes through the splash mat.
