Distilled Water Change
Distilled Water Change
I would suggest updating the loop every six months to a year using distilled water. There are coolants that claim longer lifespans, but it's better to be proactive. Even with distilled water, there is still some degradation in the tubing—especially soft ones—that can lead to buildup. Make sure to include a biocide (such as a silver plug, kill coil, or chemical biocide) and some anti-corrosion treatment. Using water that contacts more than one type of metal in the loop can cause corrosion. You'll appreciate changing it often rather than waiting too long and having to disassemble parts for thorough cleaning when buildup occurs. I recommend adding a drain to the loop to help with this.

It’s wise to add a drain point to the loop, preferably at the lowest level, with a T section or valve so you can easily empty it.
