How did life on planet Earth start and flourish without: Sellotape, the Hoover, Sliced Bread, Marmite (for some!), D.I.Y's Black & Decker Workmate, or the Guitarist's “Fender Strat."? . . . pretty tough, I guess! I now emphatically add this Balliihoo 5 Gallon Pressure Barrel to that sacred list of life’s essentials. Mine just keep going and going, brew after brew without fuss.
A Long Handled Nylon Brush, also available from Balliihoo is a good addition, to enable cleaning inside the barrel between brews . . . . . unless, of course, you know someone with 2" wide hands to get in there with the bathroom nail brush! . . . . . also for the 2" cap seal, use specially formulated, Pressure Barrel Seal Grease available from Balliihoo to ensure a good airtight seal with no fear of Contaminating the brew.
To ensure good pressure retention, there is a very useful Steel "C" Spanner for tightening the tap into the Barrel available separately from Balliihoo.
Finally, keep a few replacement 'O' rings to ensure a perfect seal every 3-4 uses.
