Know before you buy
Yes, it is specifically designed for pond-less applications. It works by creating a waterfall effect that recirculates water into a hidden reservoir rather than a traditional pond.
This unit supports a maximum flow rate of 2500 gallons per hour (gph). You should choose a pump that matches your desired waterfall intensity, ensuring it does not exceed the 2500 gph limit to prevent overflow.
The unit includes an attached landscape lid designed to be covered with mulch, rocks, or decorative stones. This allows the box to blend naturally into your garden beds while keeping the mechanical components concealed.
These fittings provide secure, leak-proof connection points for your plumbing. Having two allows for more flexible installation options, such as connecting the pump from either side or adding a secondary line if needed.
The lifetime manufacturer's warranty covers the structural integrity of the cascade box itself. It is designed to provide long-term peace of mind regarding the durability of the unit's construction.
