You say that you used 4.5G of water.
12lbs of honey is approx. 1G, which left you with a 5.5G batch in a 6G carboy.
It all sounds pretty normal to me.
Why do you think you have an infection?
What did you use for yest nutrients? (Please don't say that's what the raisins are for).
Are you doing daily aeration/degassing?
As Squatchy suggested, you should be doing your primary fermentation (and secondary, if fruit is involved) in a plastic bucket. Carboys are best used when you are doing long term aging.
Also, did you measure your starting gravity? Do you have a hydrometer? Using the Gotmead batch calculator, it looks like your starting gravity would have been around 1.136, with a potential ABV of 17.4%. Your bread yeast "might" be good for 12%, so you are going to end up with a final gravity of around 1.046, which is towrds the high end of what is considered sweet.
I used apple juice, not water.
I was just concerned about the amount of foam.
I used some Fermax and diammonium phosphate, springcell, magnesium sulphate mix I got from my local homebrew store.
I lightly shake the carboy a bit each day to degas but I have not opened it up till today (a week since it started) I smelled it and tasted some, it actually tastes pretty good so I guess its ok.
I had tried a batch before in a bucket but it did get infected with acetobacter so I decided to try the carboy since it was clean and a smaller opening should mean less exposure and less chance to get infected if I open it for any reason.
I chose bread yeast cause I figured it might impart a bit of a "bready" flavor and since i'm aiming for a super sweet apple pie flavor with a lower alcohol content that might be good (I want something super sweet for Christmas, figured the lower alcohol content might make it so I can share a good amount with the family even the lightweights).
Didn't measure the starting sg since I was afraid to let anything that touched my last batch touch this one even after cleaning it.
My next issues are that it seems to have lost a bit of the apple flavor, and what is the best method for cleaning anything that has touched an infected batch? I was gonna bleach my bucket and wash it several times with hot water but im still afraid it will infect my next batch.
