Mounted on a piece of metal conduit pipe, the Whisper waterer is easy to move around.
The "Whisper Waterer" is a modification of a small mini-sprinkler system. Typically these are run in long rows with many sprinklers and are used under fruit trees, in Strawberry patches and such. My setup is for a single sprinkler which cn be used on beds as are needed. They are nice as they are gentle and cover a small area and so can be used in a section of a garden without preventing you access to the rest.
Interested in having one made? email me and if there's enough interest I might make some. Cost around $30 shipped This email address is being protected from spambots. You need JavaScript enabled to view it.
The components of the Whisper Water are (from left to right)
Mini Sprinkler head
small hose: 3/16" Black or clear (like common aquarium air hose )
Water hose end (Green) and a piece of 1/2" hose and a metal clamp
1/2 hose coupling with a 1/2" threaded receptacle (Gray)
Threaded reducer (white)
brass nipple for small hose (metal copper)
The black knob just below the mini sprinkler and on the black hose are mini cut off valves, I have stopped using them as it's one more place for things to get clogged up.
I also have a small black plastic "riser" (sprinkler post) attached to the metal stake to achieve greater height. I screwed mine to the stake but zipties would work too.
You should be able to just assemble with the parts shown, a screw driver and knife or fine saw might help with adjusting some of the components.
I bought these parts at a hardware store. I'm sure an online search would get you all the parts you need.
