Have a new chembine chemical inductor. How much suction should you feel from the Venturi? I can put my hand on the hose and barely feel anything. Took about 400 gal of water to get 5 gal of 2-4D out of the tote. Pump and plumbing to the Venturi is 3”. Hose past Venturi to sprayer is 2”. Hose from tote to meter then to Venturi is 1”. Hoping for faster speeds. Thx.
