    How does the beer come out the top in on keg when there is hardly any beer left? There must be a tube or something that goes to the bottom. Also does anyone know if they even clean them? We have turned in some kegs that have been sitting around forever, when I pressed the ball down to see if there was any pressure left, the worst smell came out, and thats what got me thinking of how they clean the kegs?? Anyone?

    kegs are pressurised (hence the pumping) Keeps the beer flowin

    If it straightens out the wrinkles in the side of the can, it's probably too much pressure.:haha: :haha: :haha:

    no idea on psi, but i assume its not to low.

    anyone who's pumped a neer empty keg knows it takes alot. AND Bars use tanks of compressed co2 to keep taps flowing.



    generally if you get foamy beer, you got to much pressure.

    I found an empty 1 gallon keg in my front yard last month... It's got a few dents, and it's for Grolsch premium lager.......... Now it's in my room with a Poinsettia on top of it :D

    Kegs have a valve on top connected to tube called a spear that goes down from the valve on the top to the bottom of the keg. Pressurising the top of the keg forces the beer up the spear and into your glass. C02 is the best way to pressurize a keg. It also carbonates the beer giving it more fizz. Using regular old air to pressurize a keg will just make the beer go flat.
    Beer does not come pressurized in a keg. There is a little natural pressure but you need about 10 psi of CO2 to make it flow the best.

    Kegs are cleaned at the brewerey. The valve on the top is removed. It is held in place with a snap ring. Need a high tech special tool to remove it.
    Then
    They are high pressure washed inside, sterlized then inspected with fiber optics. Kegs gotta be super clean when filled, or the beer will go bad.
    But
    You really shouldn't worry about all the high tech mumbo jumbo of beer kegs.
    All you need to know is how to pour the perfict glass of beer. Preferably large and cold:D

    My roommate made a kegerator and if you want to keep the keg for any length of time, you have to use co2 and not compressed air, or else the brew will go bad. No reason you cant use air though, as long as you drink all the beer then and there.

    Logically, the keg has an air valve at the top, and a hose extending to the bottom. The pressurized air pushes the beer down to the bottom of the keg and up the hose to the tap. Any aerosol can works the same way.

    You put a tap on it, pump the tap, dispense beer into chosen container wiht the little hose.

    Then you drink it

    Repeat until you forget what to do and need to reference this thread :bow:

    depending on the beer, regulator and other factors, the required psi varies. I never had enough time to fine tune my keg before I left my kegerator at my brother's place. 10psi was a bit high for me, but I needed to replace the spigot as it leaked a bit. Another reason to use C02 as opposed to air is that CO2 is generally "clean" and air will have any bacteria or microbes that will grow in the beer to make it skunky faster. But we never had any problems finishing kegs. We were a drinking team with a rugby problem. ON! ON!
