CHWS Trev81 Hi guys, did an office today, thought I'd show the 3mm jets on 75 flow, and what its like for rinsing, I'm doing it one handed whilst filming, so excuse the quality... (This is not how I would normally rinse, just showing it for demonstration purposes) Hope it gives you an idea of how they perform. They don't cause any splash back, which means ALL the water falls down the glass, thus, creating a better, more dense rinse. As no water is wasted bouncing off into the air. With 2nm jets, it was firing out so fast, it hit the glass and sprayed all over the shop. That was slowing the rinse, and also would be more prone to spotting, most of the water was bouncing off the glass - not good for a fast rinse. (Shakespeare writing or what by the way!) 'thus' - what a word!
