Thanks for this video, Doug. The benefit I realize from using the general pump float valve is that water fills completely to the top of my tank, whereas with the other two valves, the water level is about 6-8 inches below the top of the tank(Hudson) and 3-4 inches below the top of the tank(Jobe).
What hose reel are you running your supply hose through? Don’t most hose reels carry a half inch manifold? Wouldn’t that restrict flow on a three-quarter inch supply hose bolt from the spigot to the reel and also from the real to the buffer tank?
