Line Cleaning 2-GO system has a 5 quart hand pump reservoir with a 25" line with a sanke duplex cleaning coupler attached at the line. It also includes a faucet brush, faucet wrench, and 4 oz bottle of line cleaner. The Line Cleaning 2-GO system allows you to clean keg lines at ease. Simply disengage the sankey keg, remove the beer line from the sankey coupler, connect the beer line to the cleaning coupler and pump solution back through your line and out the faucet. The one gallon solution capacity is good for even large set-ups! Use the pump to flush water through the beer lines after for a good rinse and you're set to pour more beer!
