Christmas has come early!
Inspired by the IBU Real Ale Fest on the weekend I have finally connected up the bit and pieces I received from
http://www.barleybottom.com/
I'll run through how I plumbed everything up - as I spent a while researching it and could not find anything concise on the net
Here's the order - 3/8" OD John Guest (JG) Line, Drip Trays, 3/8" to 5/16" JG Adaptors, Sparklers, a Cask Breather, Demand Valve / Check Valve. The clear hose connects to the breather with a barb and 3/8" JG fitting to make the breather have 3/8" fittings on both sides (Paul supplied this free of charge).
My intention was to have real ale dispensed from a corny keg sitting in my keg fridge like a lot of the users on
http://www.jimsbeerkit.co.uk/forum/index.php do - so the plumbing runs like this
GAS IN -- Existing 5/16" gas line in fridge --> JG 5/16" to 3/8" adaptor --> Breather --> 10mm hose? --> Barb / 3/8" JG Fitting --> JG 5/16" to 3/8" adaptor --> 5/16" line --> Gas QD --> Keg
BEER OUT -- Keg --> Beer QD --> 5/16 line --> JG 5/16" to 3/8" adaptor --> 3/8" line --> Demand Valve --> 1/2" silicon hose --> Beer Engine

The beer engine
I pulled some beer through the engine and it all ran smoothly - I did not find any meaningful restriction from the small line or keg poppet
I did discover that the demand/check valve actually stops the beer from pouring itself (this was not the case with the other check valve I was using) - as I hooked up the engine to a keg of soda water and it still needed to be drawn by the pump
This discovery kind of leads me to think the breather itself is a bit of overkill as just a quick squirt of CO2 occasionally would probably suffice
After a couple of pints I was able to flush the engine by connecting a carbonation cap to the QD (there are other was of achieving this) and drawing a few litres of water from a bucket
Also worth mentioning is that the beer lost to the engine is exaggerated as the final 1/2 pint can be collected while the water starts to enter the cylinder - I doubt that I would be leaving beer in the cylinder as it is quite easy to flush the engine
Now I've just got to make a hole in the fridge for the line and secure the breather inside the fridge (polish the brass, build some sort of bar, get a chest freezer and the list goes on...)
