Required Components:
�� x 10� PVC Pipe (The main handle is roughly 6' long. It becomes too flimsy if cut any longer.)
�� Smooth x 1� FPT End Cap with 1� MPT Plug
�� PVC Ball-Valve
�� 45-degree El
�� x �� x �� FPT PVC Offset Tee
�� x �� FPT PVC El
�� MPT CPVC/Brass Adapters (2 ea)
5/8� Braided Nylon Rope (2�+)
#8-1� Stainless Sheet-metal screws (2) > pre-drill pilot-holes to avoid cracking the PVC
PVC Cleaner & Glue (clear)
PVC Cutting Tool
Threading the rope through the two �� fittings is the toughest part (it�s a very tight fit, but needs to be in order to avoid leakage). Don�t burn the rope-ends, and make sure the ends extend far inside the PVC el-fittings. I usually �condition� the rope prior to first-use by applying surfactant or liquid soap and letting it dry - to increase the rope's wicking-action. In use, the rope should be wetted almost to the point of dripping. If dripping is noticed, simply close the ball-valve until the wick needs more solution.
Also be sure to use a much higher concentration of herbicide through this device. Coverage of the plant is much less with the wick-applicator than with spraying - so the wick-applied concentration needs to be much stronger than a typical spray-mixture.
The Type of rope used has a lot to do with the success of Wick Booms. That and the use of Silicone based surfactants can make a big difference in response. The Pistachio rope will stay wet and have little or no leakage. There really is no need for a Ball valve on the reservoir when using Pistachio rope. However the wick boom should be totally cleaned with pure water after each use if the rope wick is to work the next time. My business is pesticide application of all kinds. I use the larger Wick Booms in agriculture settings. I find one part Glyphosate mixed with 2 parts water works best on land weeds. I would start with a one to one when dealing with Aquatics.
Below is a list of Suppliers or manufacture of Wick Booms or Part and accessories. I don't have web links but google "ROPE WICK BOOMS" or the following companies I list for more information. I have several PDF files saved on my computer that are no longer on the net. If I knew how to post them I would.
