Spillways & Diffusers

AquascapePRO Waterfall Spillway

The Aquascape Waterfall Spillway is a cost-effective way to create the starting point on any waterfall or stream, providing a smooth consistent water flow. The spillway is a versatile tool that can be used in a wide variety of water feature applications. As the incoming water rushes in, the water is diffused by strategically positioned internal barriers, creating smooth flow of water.  Ideal solution for pondless disappearing waterfall systems where large and expensive biological filters are not necessary. It can also be installed as an additional waterfall or stream onto a new or existing pond. Its durable design allows boulders, gravel, soil or other creative landscape material to be set directly on top, making it easy to camouflage into the surrounding landscape. 

Features:

  • Creates a smooth and consistent water flow for waterfalls
  • Low profile and durable design
  • Handles the weight of stone boulders for concealment
  • Includes 2" PVC slip and barbed fitting
  • Channel Locks required
