DIY Budget Soda Water Kit

This kit is designed for those who don't have a Sodastream machine taking up precious bench space. But do want the convenience of taking bottled sodawater away with them.
This particular kit does not come with bottles, this is something that you should purchase from your local supermarket that suit your fridge. We find the Coles branded Sodawater bottles to be the best value and have very strong threads for our Carbonation Cap to attach to. 
If you are wanting more than 1.25L at any one time, I would suggest purchasing extra Red Carbonation Caps here. These caps are also extremely useful if you open a bottle of soft drink and don't finish it. Don't you hate it when it goes flat in the fridge next time you go to take a drink. Now you can whack one of these Carbonation Caps on and pump it up before you put it back into the fridge, it will maintain full carbonation!
Installation:
Install the Regulator to the 2.6kg CO2 Bottle with a length of hose that suits your needs. We'd suggest around 2m or so. Ensure you cut straight and cleanly. No burs or cuts.
Attach the grey push in connector to the Regulator. Then attach the length of hose to it, ensuring you have pushed it as far as it can go in.
Then attach the opposing end into the Red/Grey Disconnect, again push it all the way on.
What what we are going to do now is a pressure check to ensure you don't lose an entire bottle of gas.
Turn on the 2.6kg Cylinder from the black handle ontop of it. The left hand side gauge of the regulator should shoot up (don't worry about the value) Next we will increase the pressure on the regulator up to 30psi then turn off the 2.6kg Cylinder pressure. Come back in an hour or so, if the regulator is reading zero. Then you'll have a leak somewhere in the system. Ensure everything is just a little bit more tight than hand tight. Check the hosing with soapy water if you're still experiencing leaks.
