Sparging Tips

To introduce sparge water to the grain bed in your picnic cooler, water cooler, or modified keg mash tun, you can construct a simple sparge sprayer out of CPVC pipe. Simply obtain two lengths of thin CPVC supply line (⅜″ will be fine) and cut one to the length of your cooler or to the diameter of your modified keg (the other length will be slighter longer than the width of your cooler or the diameter of your keg). Next, cap one end of this pipe and drill very small holes in the pipe (see illustration below).

To do this, we acquired a couple of 1/32″ drill bits from a hobby shop (they break easily!) and drilled holes about ½” apart on one side only along the entire length of the pipe. Glue the second length of CPVC, which is cut a bit longer than the cooler’s width or keg’s diameter, to the long tube and at a right angle to it. The second pipe simply supports the sprayer and provides stability when it’s positioned over the top of the cooler.

Now push the vinyl tube over the end of the CPVC tube. Depending on the size of your hose, you may have to add a hose barb adapter to hook the CPVC to the vinyl hose. If you use ½″-diameter CPVC pipe, a ⅝″-diameter I.D. (inside diameter) poly hose will fit tightly over the end. Then siphon the sparge water into the sprayer.
