So, how do you monitor for a leak near the hot zone?
Electrical leakage to earth. My coolant is at something like 40 psi so a small leak goes a long way !
I keep my coolant circulating for quite a long time after shutting down the driver electronics as if I stopped the pump too soon the now static water in the coils would be in grave danger of boiling
