Christopher 102 Report post Posted October 27, 2004 Hello Everyone, I am getting ready to install my downstream injector I purchased last week. I was looking at it and the passage through it is very small. I am thinking that this will cause some back pressure for the pump if it runs all the time. Does everyone install this before the hosereel or just before the gun or after the gun? I am thinking that maybe I need to put in a "T" so I can by-pass it when I am not injecting chemicals. Does anyone have any pictures to share so I install it correctly? Thanks for any help.
