===== Keg Line Clean (Permanent Lines) =====

^ # ^ Step ^ Comment / Troubleshooting ^
| 1 | Empty the 50 litre plastic tub and fill it with clean water from the hosepipe. |   |
| 2 | Turn the compressed aire switch above the tub from "NORMAL" to "CLEAN". | This opens the cleaning circuit to the wall-mounted compressor, giving you the pressure required to pour water and cleaning solution through the lines. |
| 3 | Turn off the gas valves connected to the green and white circuits on the wall. | You do not need to turn off the blue circuits, which is compressed air.White and Green lines are connected to the gas cylinders. We do not want the extra pressure from these lines applied to the circuit as we clean: the compressed air from our compressor is enough. The line clean will still work if you don't do this, but it will put stress on the circuit and may damage it and cause gas leaks in the future. |
| 4 | Connect the keg couplers to the wall-mounted cleaning circuit. | Most - but not all - couplers fit the socket directly above the barrel. Pardal, Staropramen, Hell Rat, Aspall, Appleshed, and Wipeout all use the Sankey couplers. Aspalls is the only one that seems to fit the smaller metal Sankey fitting.Guinness uses a U-type coupler, that slides over the black fittings.Blue Moon and Leffe Blonde use the triangular Grundy couplers and need the blue sockets. |
| 5 | Go to the bar and pour the pumps into plastic jugs until clear water is running through. | If any of the pumps stop, this could be one of two reasons: first, check that the buoy hasn't dropped. Secondly, make sure you've completed step 2 and the compressed air valve is open on the cleaning circuit. |
| 6 | Dispose of the beer and water in the toilets | This is simply a quirk of our pub. The cleaning area sink doesn't drain particularly well, and can fill faster than it drains during this process. If it is full, it can drain back upwards into the glasswasher, which we do not want. |
| 7 | Refill the tub and add line cleaning solution | Check the container for proportions. At the time of writing, our line cleaner works best at 75ml per 5 litres, so a full tub would need 750ml line clean solution. |
| 8 | Pull line cleaning solution through the lines until it is clear purple | Some will be purple immediately: Pardal and Guinness tend to go through a green stage. Purple line cleaner changes colour on contact with bacteria and yeast. |
| 9 | Wait 20 minutes | There will be a lot of cleaning solution left in the tub, so pull more through to freshen up the cleaning fluid in the lines during this period. |
| 10 | Empty the tub onto the cellar floor and re-fill it with clean water. | After emptying it, you will probably see a small puddle of purple left in the bottom of the tub. Put a litre of water in and empty it out again so there's no cleaning fluid left. |
| 11 | Pull clean water through the lines. | It can take a lot of water before there's no trace left of cleaning fluid. You can speed up this process by hand-venting the cellar bouys to clear the purple fluid before starting. |
| 12 | Reconnect the couplers to the beers. |  |
| 13 | Turn the cylinder gas back on at the wall for all beers. |  |
| 14 | Turn the compressed air back from "CLEAN" to "NORMAL" |  |
| 15 | Pull beer through all the lines |  |
