Water is continuously re-circulated from the hidden central reservoir. Only occasional topping-up is required to replace evaporative loss.

The submersible pumps are adjustable so you can control the rate of flow over the cascades.

Installation is very easy. The central reservoir and cascade vessels locate neatly within the timber structure. The pump needs no priming and the return-pipe to the top of the cascade system a simple push fit. All necessary pipe and fittings are included.

In normal conditions the pump is virtually maintenance-free, requiring no more than an annual check of the filter.
