The Atlantic Water Gardens SP1900 Big Bahama FastFall is a heavy-duty, one-piece spillway engineered for pond-free waterfalls and disappearing streams. Its reinforced design makes top-of-waterfall plumbing simple and reliable.

  • Waterfall width: 19" for a broad, natural-looking sheet of water.
  • Dimensions: 20.5" W x 17" D x 10.25" H - compact footprint for easy concealment.
  • Max pump flow: 4,000 GPH; inlet: 2" FIPT (Spinweld fitting pre-installed).
  • Molded support cones and internal baffles ensure strength and even water distribution.
  • Raised front radius and reinforced spillway lip retain rock, gravel, or planting for natural camouflaging.
  • One-piece liner flange and molded inserts provide a secure, watertight liner attachment; installation kit included.

Designed for installers and hobbyists, the SP1900 simplifies construction of pond-free features: conceal the unit with rock and planting, connect standard plumbing to the spinweld fitting, and adjust flow to suit your design. Refer to the included manual for installation details and recommended accessories.
