This simple pump kit is a great way to clean your draft lines when you don’t want to waste CO2 or mix up a full batch of line cleaner. The PCO tee piece can be attached to a PET beer bottle or repurposed soda bottle, then pressurized with the hand pump to push cleaner through your ball lock disconnect and draft lines.

You can also use the pump kit to turn just about any PET bottle into a mini party keg; one that’s easy to take with you while leaving your gas equipment at home. But since you’ll be using air to push the beer out, we recommend consuming the contents of the bottle well within 24 hours.
