Installing the Elite 28" Spillway
For pond-less waterfalls, a pump moves water from a hidden reservoir through plumbing to the spillway. Water then flows down the stream and recirculates into the underground basin.
Proper placement, leveling, and liner connections are essential for reliable waterfall performance.
1
Prepare the Location
Choose the spillway position, prepare a stable base, and route the water supply line.
2
Position and Level
Level the spillway side to side, with a slight forward tilt of approximately 1/4 bubble on a 2-foot level.
3
Connect Liner and Plumbing
Use the supplied 2-inch elbow and follow our installation guide for the liner connection and watertight sealing.
4
Test and Finish
Check water flow and connections before concealing the spillway with surrounding rockwork.
Installation Tip
Leave some extra liner around the spillway for adjustments. Position surrounding rocks to direct water into the lined stream instead of behind the waterfall.
Maintenance and Seasonal Care
- Remove leaves and debris that could interfere with water flow.
- Periodically inspect plumbing connections, rockwork, and reservoir water levels.
- Follow our pond-less maintenance and winterization guide for seasonal shutdown and spring startup.

Frequently Asked Questions
Does the Elite Spillway 28" include a pump?
No. PB2866 is the individual spillway box. A pump, reservoir, liner, and other waterfall-system components are sold separately.
What size pump should I use with this spillway?
Pump selection depends on your desired waterfall appearance, vertical lift, plumbing length, and system configuration. The published maximum pump flow is 7,800 GPH, but this is not a required operating flow. Contact our Sales/Tech Team for help sizing your pump.
Can I use this spillway with an existing waterfall system?
Yes, provided your installation has adequate space, suitable plumbing, and compatible water flow. Compare the spillway dimensions and 2-inch inlet before ordering.
Can this spillway be used for a pond-less waterfall?
Yes. Our Elite Spillways are designed for pond-less waterfalls and cascading streams. The pump and hidden reservoir continuously recirculate water through the waterfall.
How do I prevent water from flowing behind the rocks?
Proper liner placement and rockwork are essential. Our installation guide recommends sealing gaps around waterfall stones with waterfall foam to help direct water over the visible rockwork and back into the lined stream.
What maintenance is required during winter?
Winter care depends on whether your waterfall remains operating or is shut down. Check for ice dams and water loss when running in freezing conditions. For shutdown, follow our maintenance guide for pump storage and spillway cleaning.
