Jazzcnc,
I hope they learned their lesson.
Jonathan,
the problem with using water is that bacteria can grow in it quite well. Distilled water is a better option for long term. I have been to several factories in the past where they were too tight to buy distilled water or the correct coolant for their machines and eventually the bacteria hard grown into a type of algae or fungus and it blocks up the pipework. This usually meant an expensive repair for the customer.
We use distilled water for coolant on our Co2 Laser at work but we also add 1ltr of an anti bacteria agent to kill anything that might decide to grow in the coolant. This amounts to a 1% mix and the whoile system is drained and refilled with new coolant once a year.
A few years ago I miscalculated the amount of antifreeze required for the system and put in too much. Not quite sure what chemical reaction took place but the coolant mix started to turn to a gel. Right PITA is was to clean out. Now we go for about a 15% mix in winter time.

I didn't mean just use tap water - that would be rather silly. I meant tap water plus some anti bacteria stuff/antifreeze.
