Not a point where I can afford a ride-on yet, so putting together a backpack sprayer rig for blanket weed apps. I need some feedback... I have this Chapin 4 gallon electric sprayer. Specs say 35-40 PSI. Thinking of putting this 3 nozzle boom on it: https://www.amazon.com/gp/product/B006Y850A2/ref=ox_sc_act_title_3?smid=ATVPDKIKX0DER&psc=1 But I am concerned about the PSI being great enough to adequately use some TeeJet AI tips. If I go with the green AI flat spray AI80015, 30 PSI at 3MPH will give about .29 gallons per 1000K, which is where I would like to be. I just wonder if the pump can keep up with 3 nozzles, there is also a 4 nozzle boom, but again same issue. Also I was thinking of putting the 29 PSI regulator that Chapin makes, just to be sure my pressure is consistent. Any thoughts?
