Took the pics, but then the wife needed the camera. Stay tuned.
Looking closely, the first inch or two is not as good as I would like.
I might drill a hole from the top, just before the start of the screen, and insert a small pipe.
That would act as a baffle, and slow down the flow in the beginning.
And if it does not work, it is just another overflow hole.
I am also considered bringing water into the slot pipe from both ends, but the extra pipes become a big hassle.
