This wand is very useful when using together with the clever injector. We did manufacture our own wands with all the correct equipment just like the US use. We found that they lasted on the ball valve the same amount of time as this one. So therefore we only promote this wand for sale. It is simple to use comes with two nozzles one fan and one pencil. The pencil is great for projecting onto roof washing. The fan nozzle is perfect for flat work. The ball valve handle allows you to adjust the flow rate when necessary. It also comes with a male hose connector. Simple to use and effective and reasonably priced for replacement when necessary. It’s always good to have a second one in your van for when eventually the sodium hypochlorite claims its victim.
