20 includes nozzles made entirely of plastic. It is not adjustable, it can be especially close completely. The nozzles are distributed over the entire length and fit together to force T can not orient. Spraying is relatively fine if you do not open all the nozzles, but it wets very quickly: this is not the mist! Even with a single nozzle having all the pressure, it wets !! In fact, this is an excellent irrigation system by spraying ;-D There is no filter on the water inlet comprising a garden fitting of 2 adapters.
