Think what would happen if you cut the pipe off 1 foot below the level
of the water in the pipe. You get a gusher. To stop the flow you put
the pipe back together using a pipe slip coupler.

This works best it the pond has one edge that is built up. That way the
pipe
can exit on the low side and be exposed below the level of the pond
surface.

I get ya now, that makes sense. Thanks for the tip. I think I will
incorporate it.
