									Reconditioning a Cornelius

By Chris
                Before we start….
Thanks for taking the time to have a look at this. Let me just say that
  this is a record of how I conducted my first keg reconditioning. I’m
  not saying it is the best (or only) way to recondition a keg as I’m
  sure, in the homebrewing tradition, others have found a method that
  works for them. This was the first time I had attempted to recondition
  a keg and to be brutally honest, its dead simple and a really easy
  way to save potentially 100’s of dollars if you compare it what brand
  new kegs cost.

Cheers, and I hope you get something out of it!

          Cleaning the Keg
Pull the keg apart i.e. lid, posts, dip tubes
 and place all these pieces loose inside the
 keg in a cleaning solution to soak
 overnight. (I use 2 caps of unscented
 napisan and it seems to work quite well)
        Cleaning the outside
I use some warm soapy
   water and a scourer. For
   the really tough marks /
   glue / labels or dried syrup
   I use this car cleaning
   product. It works a treat!!.
• PRV – Pressure Release Valve
• HBS – Home Brew Store
            Replace rubber
Go to your local HBS and buy a
 reconditioning kit (about $15). This should
 contain a large O-ring for lid, 2 poppets, 2
 tiny o-rings for dip tubes and 2 slightly
 larger o-rings for the beer and gas posts.

Replace all the rubber (don’t mix them up!!)
Corny Keg rebuild kit. About $15(aus) from local HBS
             A note on lids
Lids like the one circled in red on the next
   slide have an older style PRV which are
   very hard to come by these days. As the
   more common PRV’s do not fit the same
   hole as these PRV’s you have two
   options if you find they leak gas:
1. Buy a whole new lid (approx $25 ea)
2. Do what I did (see later in this tutorial)
Older style Corny Lid
        Put it back together
After all rubber has been replaced and the
  new poppets installed, replace dip tubes,
  posts (make sure they are tight), PRV and
  fix lid in place.
           Pressure test #1
Connect the gas line and turn on the CO2.
Burp the keg a couple of times and let the
  keg fill for about 30 secs.
Remove gas line and find a quiet spot to sit
  with you beloved keg!
Listen really carefully around lid, PRV and
  posts for any hissing. No hissing is a good
Connecting the gas
          Pressure Test #2
To be extra sure your keg isn’t leaking use a
 small syringe or something similar to squirt
 water around all the seals. Bubbles will tell
 you have a leak (hard to see but they have
 been circled)
             PRV Trouble
My ‘old style’ PRV had a slow leak no matter
 what I did. Rather than buy a whole new
 lid.I made sure the washer was replaced
 and then I got some good old ‘Gorilla Snot’
 (Selleys No-More-Gaps). I haven’t had a
 problem since.
Four kegs off ebay:         $201.40
Reconditioning Kits:        $ 60.00
Time and effort:              N/A     (how can you put a value on something you
Total cost per keg:         $ 65.35

I had napisan and the bug remover spray already at home. If you needed to
purchase these the Napisan would cost about $5 for the same sized container
but you would only use ½ of it. The bug remover cost about $15 for the bottle but
I estimate you could clean 15-20 kegs with it as a little goes a long way.
All up it is very easy to recondition a keg for less than $70 each. You can’t buy
them that cheap and it is really easy to do!!
