Ball valve install between the end of the hose and the brass quick disconnect at the end of the hose. Use to turn the water pressure off at the end of the hose so you do not have to walk back to the machine to turn off the water pressure Turning off the water pressure at the end of the hose is a huge time saver. Example: If I am on a second story cleaning job and my carpet cleaning machine is on the first floor, to change from my injection spray, to my hand tool, or to my floor wand, to my under the bed cleaning tool, I have to remove the water pressure. So I have to go down stairs and turn my machine off, go upstairs and change my tool out, go down stairs and turn my machine back on. I could avoided all this calorie burning by just turning the water pressure off at the end of my solution hose, changed out my tool, turn the ball valve back on and go right back to work.
