Transition between a 25mm pump hose and a waterfall head. Semi-laminar flow output (there are baffles to handle the change in direction of flow.

Hose is designed for side-entry (my pond has the waterfall on a narrow side against the fence) and can be built into blockwork or stones.

Earlier design had a narrower jet, and splashed on the far side of the pond. This oner has a wider jet, and flow restrictions at the edges. Not perfect, but seems good now with a fairly small throw on the jet, and not too much leakage.
