I got my RO unit from PureWater Club and have it mostly set up. But in the instructions it mentions how the waste water has to have back pressure to work. My problem is that I don't see a back pressure fitting. I don't have that part that is pictured. Is it already attached to the unit when you get it? Maybe I am not seeing it. I want to get it running before I need to go buy more water.
