Know before you buy
This spillway is designed to handle a maximum pump flow of 4,000 gallons per hour. Exceeding this flow rate may cause water to overflow the sides of the unit rather than creating a smooth, controlled cascade.
Yes, the unit is engineered with internal support cones and a crush-proof design specifically to bear the weight of rocks and stones. This allows you to camouflage the spillway naturally into your landscape without worrying about structural failure.
The SP1900 is specifically designed for pond-free waterfall and stream applications. It is intended to be buried at the head of a stream where the water disappears into an underground reservoir.
The unit features a dedicated bulkhead fitting and a secure liner attachment system. When installed correctly, this creates a reliable, leak-proof connection that prevents water loss at the point where the liner meets the spillway.
The unit includes the essential setup accessories, including a 2-inch FIPT bulkhead fitting. You will still need to provide the appropriate PVC or flexible tubing and the pump to complete your plumbing system.
The internal baffles are designed to diffuse water for an even flow and generally require very little maintenance. However, it is good practice to periodically check for debris or sediment buildup that could obstruct the water path and affect the look of the waterfall.
