  1. My lines and cellar boys keep draining, i have all gases to kegs of and main gas on. I am completely stuck! Ive done this a million times and its never happened. Please help.

    • You probably have gas seeping into the cleaning line through the cleaning fitting, well 95% of the time.If you are sure you have turned all the gasses off, you can test that those on/off switches aren’t faulty by removing the coupler and check to see if the gas, really is switched off. If you do have a faulty one you can leave that one off, and clean the rest of the lines and do that one on it’s own later. Then get tech services to change the faulty gas valve.

      If it definitely isn’t that, check the line from the cleaning container to see if any bubbles are coming up from there. If there are, make sure the plastic nut on the top of the bottle cap is tightened fully home.

      If bubbles are still coming up the tube, remove the cleaning bottle cap and inspect the rigid plastic tube for any splits; if there is, as a temporary measure (quick fix) you can pull this pipe off and turn it around. I think this covers most of the problems relating to gas or air in the cellarbuoys while cleaning. Hope it helps.
