Laaz I tried your hose method using Dawn Soap and the same bottle you showed in your post. Sorry for a new thread but I could not locate your original post demonstrating the method. I have a couple questions. Do you mix the Dawn with water to make the soap solution less thick? I sprayed 9 large in ground trees (actually 3 times over) and when I was done the soap in the bottle had hardly gone down. Any suggestions or help. I really want your suggestion to work, as I have been using a backpack spray and that method is a real hassle. Appreciate your assistance.
David, I have that same chapin sprayer. It does not work for me when spraying soap or hort oil. I also tried a chameleon one, and a repurposed disposable hose-end sprayer. None of these worked, they would pick up the concentrate for a very brief time then not at all. I spent hours messing with them, trying to tweak them, but I could never get anywhere close to acceptable performance and went back to my pump sprayer.
i tried varying levels of concentrate including nearly pure water but it would never be picked up consistently
in another thread, I believe Laaz posted that he uses a chameleon sprayer
Lazz you did not answer my question. I used the exact spray you show in the above picture (Cutter Backyard Bug). It is doing the very same thing as Brian's. It draws the Dawn soap up for a brief period then stops. Dawn soap must be two thick for a syphon sprayer. I even thinned the Dawn soap down in half with water and still the same thing. Did you use the soap straight?
I wonder if the water line pressure matters, I can't think of many reasons why hose-end sprayers would work fine for some and not at all for others. Maybe try opening the valve part-way only to reduce the pressure and see if you get different results? I never tried that.
I would be happy to find such a tool in Europe. So far I couldn´t find it. It seems to be very helpful.
If someone knows where to find it in Europe please contact me.
Edit: I just found out I can buy it on amazon, but that was the point on my last research the conection to the hose is different from german standards. So it needs an adapter. What kind of hose connector do you use in the US?
Hose end sprayers work upon the fact that the water passes over the soap vessel creating a syphoning effect. If you do not have a water and air tight system they will not pick up and distribute the soap soloution. This means hose washers in all the appropriate places and good tight connections. If you are drawing air or water at any place they will not pick up the soap. I fought a cheap one for about two weeks. Could not get it to pick up soap....turned out that I had a plastic washer in the bottle. Replaced it with a good rubber washer and it went to work. You have to have a good tight system.
