To use, just put on top of your grain bed in your lauter tun, and adjust your valve until an inch of water is above the grain bed. Open your lauter tun exit valve, and keep about an inch of water above the grain bed for even sparging. Continue until you have finished sparging and then turn off.
Simpler and easier to use than a Sparge Arm, and just as effective. Fits any valve with a 3/8" hose barb (so it can be used with a wide variety of systems). The silicone hose is 4' long,and the stainless steel float features a 3/8" opening for the tubing.
