Stream Components
The stream comes in 5 ft sections that interlock with the next section. 
Each section is made at different heights, so the water starts at the top and
simply goes down to the lower pool to recycle.
The stream requires no digging, just a flat area.  Everything is above ground. 
Comes complete with pump and hoses.  Sets up in minutes - Just add water and plug it in.

There are four parts to the stream.  The pool, section one, section two, and the fountain head.
In the below picture you can see a top view of the four parts.
In the picture below you see a side view of the parts.

In this picture below, you see how section two, three, and the fountain head can be
attached straight on or at +60 or -60 degrees off the center line.
This allows the stream to curve as you desire.
