Know before you buy
The SP1600 is designed to handle a maximum flow rate of 3,000 gallons per hour. Exceeding this flow rate may cause the water to overflow the sides of the spillway rather than creating a smooth, controlled cascade.
Yes. The unit features a crush-proof design reinforced with internal baffles and support cones, allowing you to disguise the box with heavy rocks and landscaping materials without risking structural damage.
The rear liner attachment creates a secure, watertight seal where the pond liner meets the spillway. This design eliminates the need for messy silicone or unreliable seals, ensuring water flows into the spillway rather than leaking behind it.
Absolutely. The SP1600 is specifically engineered for pond-free applications, providing a clean, professional start to your stream or waterfall while keeping the plumbing hidden.
The inlet connection is a 1½-inch FIPT (Female Iron Pipe Thread). You will need to use appropriate fittings to connect your pump tubing to this standard size.
The Atlantic FastFalls SP1600 comes with a lifetime warranty, reflecting the manufacturer's confidence in its durable, crush-proof construction.
