This is what I use, thanks to @Racer. 1/2in Barb to thread 1/2 threaded pvc ball valve 18in 1/2in threaded pvc pipe 1/2in pvc female to female 1/2in male to 1/4in female brass reducer 1/4in quick connect for your nozzle [Screenshot_20191219-230541] It can all be found at home Depot. The nozzles I use are 2540 and 0040. I have a 5.5gpm with 200ft hose. The more hose you use the less GPM you get but I wouldn’t roll with less than 200ft
