Actually the last 2 days, but I completely tore down my venturi spray rig over the last few weeks, and rebuilt it from scratch. I eliminated as many issues as I could from version 1, and came up with this. The only moving parts are the pump and venturi dial, and no chemicals ever touch the pump. It's paid for itself a dozen times in time savings alone.
I treated 4 surface acres over the last 2 days, and other than slotting the tank for the suction hose and tank mixer wiring, it's good to go.
