Building A Waterfall

[digitele]

I am in the process of trying to design / build a waterfall.

I understand the basic concepts and have selected a "step" type as my model.

The one pictured had a 7.5 HP motor. Mine won't be as high ( elevation of outlet nozzles )

so I have to determine motor size and manifold - The pictured one had 13 output nozzles

yet on the pump side had only one visable pipe.

They had to build a manifold or T type splitter. I an really concerned about this aspect.

It's one of those things you have to get right as you won't know until it's built (wrong!)

Appreciate any advise of suggestions. Thanks in advance.
