Hi all, I'm no stranger to watercooling, been doing it for the last 10 years but the build im working on now is my 4th hard loop ive ever done. This is the first leak ive ever had and luckily i had it in leak test. I had a seperate PSU pin modded with only the water pump on to complete the leak test. It was running for about 5 minutes until one of the hard push fittings at the bottom left of the pump burst (see picture below prior to testing). Water maily dropped below into the lower section of the case where i had nothing but i had alot of splatter on the underside of the GPU and on the bottom of the MOBO. I'm looking for things to do to be ultra cautious before i go testing equiptment or turning anything on? Things ive done already: Removed all parts, pulled apart water blocks and any peices of any part and seperated it all onto a counter top with a mild heater pushing warm air on them for 1-2 hours. use a bit of alcohol with a brush on sections that got really wet and wiped it off thoroughly. Pull all components out of my case including all water loop parts and cleaned them thoroughly. Let all parts dry for about 6 hours after doing the above Tested some minor equiptment that didnt get water on it to rule out an future failures. Eg PSU, fans, lights, water pump. confirmed working. Installed all the parts back into the case including water loop. With external PSU got all case fans to run overnight and will leave them till this afternoon so roughly 18 hours. Want to get a good flow of air going through the case to dry of anything ive missed. I've fixed the fitting that burst with a new fitting and also put compressed air via the water drain valve into the loop and going to be leaving that compressed air in for 18 hours to see if the pressure holds.
