o.k., i have one and it really squirts the water out, all over. now i read that it is controlled with that little plastic thingamajig in it. which do you use for a pressure system?? with the plastic insert with tiny hole, or take it out? i know it is somewhat of a dumb question, but i do not want to get the pipe wrench and take it all apart, only to find out it was hooked up right to begin with and i wont make it any better.
