One small hole through a wall can be all that's really needed to run a line of 1/4" ID ice maker tubing to a float valve. Odds are you have incoming water in the next room....there's the source. Holes through drywall are easily fixed.

There are ways to setup a 2-liter bottle, gallon jug, 5gal bucket for short-term auto-refill.....
See text in bold!!!!

NEVER DO THAT... EVER!!!!!1111 Crap in the water will eat your water block in no time! Probably trash the ac evap in short order.

Never use anything in a water loop but pure Reverse Osmosis treated water. If it is a chiller, buy a gallon of cheap vodka and your set to go.

Is buying water and separate denatured alcohol cheaper? Not usually, after you have driven to get the water and then you drive to the home improvement store to buy denatured alcohol it's usually a wash. You can get a gallon of skunk vodka at the nearest Liquor store for 10$ around here. Pure water and ethanol.

NO TAP WATER!!!
