extream, i hope you mean 4 to 1
4 gal of water to 1 gal of chem. that's a 20% draw.
A 5 gal per min unit with the best e-spec downstreamer should draw 1 gal plus 1 qt [5 qt's] per min.
Less if you run over 150 ft of pressure line and dont move the downstreamer closer to the wand.
Another question. Do you think if you were to try 2 downstreamer's on one pressure line, would you space them with a jumper line or connect them together?
