My two cents' worth of suggestion:
Get a bag of ice from your local convenience store, and put it in the fridge. The bag will hopefully keep the water from draining everywhere in the fridge, you will have ice for your drinks, and you won't have to modify anything. An 8 pound bag of ice is currently $1.59 at the 7-11 on the corner, it will take a lot of them to pay for even a small conversion.
Meddle not in the affairs of dragons, for you are crunchy, and taste good with ketchup.
