I started hacking away at a water cooler that I had at my shop since no one uses it to drink water. I thought that I could use the cold water to cool my system. I fiqured I could install the pump directly inside the metal container that holds the water. I had filled up the unit with water and by pass the temp switch and I got some ice within 5 minutes. Has anyone tried this? Is there any draw backs? I had seen people using the large ac units which I dont have the space for, looking for something compact and fiqured that It would work out fine. Any suggestions it would be great.
