Methven Kiri Satinjet Ultra Low Flow showerhead jet system designed engineered and manufactured in New Zealand.  The best shower with the least water.   Not available at Bunnings, Reece or elsewhere who only sell the higher flow 7.5L versions (look almost identical).  Works best between 200kPa and 500kPa which is your normal Australian standard water pressure. Some older instantaneous gas units may not handle the low flow of this showerhead but these units are rare. Utilised once for a quality assurance test.  Every shower head has been run and tested once to ensure the best experience. Formerly Methven Kiri Low Flow Satinjet Rose WELS S11333
