Quoted from Coyote:

You need to contact a Coke (or Pepsi, whatever) distributor. Syrup is delivered in large boxes, and depending on the machine, will either be connected to an external vacuum pump or to the internal vacuum pump via a reinforced hose.
Be prepared to pay for the syrup - last I was in the business (1999), the boxes were $150 a piece. Granted, that box lasted us two months in a popular pizza / FEC location, so for you, a box will likely last all year.
You also will need a CO2 canister, which will connect to the vacuum pump as well. Depending on the size, can range between $50 to $300.
And then, you'll need your water hookup.
Good luck - once you get it set up, it's really nice (better than canned soda..) - especially since you can adjust the mixture in your nozzles. (i.e. Diet Coke too sweet? Turn up the CO2/Water mixture!)

Hi
I have a fountain system in my place. If you need pictures or any specifics please let me know. Not sure about the aforementioned pricing but a five gallon container of coke syrup (bag in a box) can be had at Sams club for about $75. This is where I buy my coke. I also get bag in a box birch beer for even less than that
Let me know if I can assist

Quoted from sevenrites:

Damn, it would be pretty sweet to have a fountain soda machine in the house...

Quoted from GPS:

Do you by chance have a manual for the machine. Sounds like you have a built in carbonator. It is possible that the nozzles are clogged. They usually get. Leaned every night when in a restaurant situation, at least they should. I do know that in my carbonator there is a float switch that I have had to replace.

Quoted from Coyote:

When you activate it, do you hear a 'click'? There's a valve that should get power and open the line when the actuator is pressed in. If you Do hear a click, then yeah, it's likely just gummed up.
