I saw something on T.V. the other day and I thought you might know where I can buy it. The best way to describe it is it looks like a big (about 18 inches wide) harmonica. A single hose connection goes in the back and water comes out multiple holes in the front. Appreciate any help - thanks.
I have never heard of it, let alone seen it. It sounds like a simple manifold and would be easy to build yourself. I have had some experience with 'prefab' waterfalls and pipes or fountain heads with holes in them and very often the holes will clog up. Pretty soon, only one hole is left unclogged and is shooting water out of your pond. It can drain your pond and drive you crazy trying to keep the holes clear.
