Can I use tap water to test my system?

post #1 of 18
Thread Starter 
I haven't gotten my PC ICE in the mail yet and I was wondering if I can use tap water to do the leak test. Or will this put minerals and other junk in the system and contaminate it?

If you have a water purifier then run it through that first... Your best bet would be to just wait it out though.

Yeah, you can use tap water for leak testing, but I really wouldn't keep it in there for more than 24 hours or so.

Alright, I was going to run to the store and get some distilled water, but that would require wayyy to much effort. I mean all that driving, and walking, and then trying to find it, the trying to find a short line, and then paying for it, then to drive back home. Soooo much stuff to do. Ill let UPS do my biding and wait.
Oh and thanks for the reply.

Tap water has more stuff in it that you may realize. Honestly, is paying $0.69 at the grocery store for a gallon of distilled water that expensive?

Tap water IS VERY VERY BAD for waterblocks, and RADs. It has fluoride and chlorine. The tap watter will destroy radiators and heatercores, because of all the junk in it. DO NOT USE TAP WATER, EVER. Only use idstilled water. Trust me, I almost ruined my heatercore by usinging tap water.

I read a very technical post in which some developers of waterblocks pretty much said that it would INSTANTLY begin to degrade to heat-shedding properties of the copper--if there is a disimilar metal in the loop (like an aluminum rad of stainless impeller shaft). One poor fellow had just run tap water through his new waterblock to test the system for leaks and then blew it out--but a patina had already formed on the waterblock--that fast. What may appear to be a little discoloration is actually a change in the metal's surface structure--the salts in the water from the chlorine and flourine form a microscale on the copper effectively insulating it from the water and reducing the ability of the heatsink to transfer the heat it has drawn off the CPU into the water.

When I say NO, it's because I have some small understanding of elctrolysis and why go do something that professional waterblock developers warn against... (See ProCoolingForums if you are curious...)

Yes, tap water is very bad for a water loop, and yes, it will cause damage. However, a few hours of leak testing will not produce any undesirable effects. Sure, on a microscopic level it might induce electrolysis, but are you going to notice a difference in temps or see discoloration in your block....no.

I have been reading Procooling for years now, and I understand what you are saying. However, I have done this many times, once again, for only a few hours at a time, and I have never seen any negligible difference in either performance or color of the copper.

Edit: I say this ONLY if you are using an entirely copper/brass loop. If you have aluminum in it, then NEVER use tap water.
