Why Choose Our Elite Spillway?
Even Water Distribution
Internal baffles spread incoming water across the spillway for a consistent waterfall flow.
Compact, Low-Profile Design
At only 5 inches tall, the spillway can be hidden behind natural rockwork without a bulky waterfall box.
Ideal for Pond-Less Waterfalls
Designed for recirculating waterfalls and streams that use a concealed underground reservoir.
Spillway Box Only — Not a Complete Waterfall Kit
The PB16ES is the individual spillway box. A complete pond-less waterfall also requires a pump, reservoir, liner, plumbing, and installation materials.

Maximum flow is the spillway's rated capacity, not a recommended pump size. Choose your pump based on desired flow, vertical lift, and plumbing restrictions.
Installation Planning
Proper positioning and plumbing are essential for even water distribution and keeping water within the lined stream.
1
Position the Spillway
Prepare a stable, compacted base. Position the spillway level from side to side with a slight forward tilt of approximately 1/4 bubble on a 2-foot level, as specified in the installation guide.
2
Connect the Liner and Plumbing
Position the waterfall liner and connect the 2" street elbow through the liner into the Spinweld inlet. Follow the manual's sealing and plumbing instructions.
3
Finish the Rockwork and Test
Conceal the spillway with surrounding stone. Start the pump, inspect for leaks, and confirm that water flows evenly into the lined stream.
Choosing the Right Pump
The PB16ES supports a maximum flow of 4,500 GPH. Actual flow at the spillway depends on pump performance, vertical lift, and plumbing restrictions. Select a pump that delivers your desired waterfall appearance without exceeding the spillway's rated capacity.

Frequently Asked Questions
Is the Elite 16" Spillway a complete waterfall kit?
No. PB16ES is the individual spillway box. Pumps, liners, reservoirs, and other installation components are sold separately. For a complete system, consider our Elite 16" Small Spillway Falls Kit (PB16KIT).
What size pump do I need for this spillway?
The maximum spillway capacity is 4,500 GPH. Choose a pump based on the desired waterfall flow, vertical lift, and plumbing restrictions. The actual flow delivered to the spillway must remain within its rated capacity.
What's the difference between the 16" and 28" Elite Spillways?
Both feature a 5-inch-high, low-profile design and a single 2-inch inlet. The 16-inch model supports up to 4,500 GPH, while the wider 28-inch model supports up to 7,800 GPH. Choose based on your desired waterfall width and system design.
Does the Elite Spillway filter pond water?
The internal baffles distribute water evenly across the waterfall opening. The spillway is primarily a water-distribution component, not a replacement for dedicated biological pond filtration.
What warranty comes with the Elite 16" Spillway?
Our engineered plastic spillway boxes carry a lifetime limited manufacturer's warranty against manufacturing defects for the original purchaser. Installation must follow applicable instructions. Product modifications can void coverage, and labor and freight costs are excluded. Refer to the official warranty document for complete terms.
