Is tap water really that bad?

post #1 of 6
Thread Starter 
Hey guys,
I was just wondering if tap water is really that bad? I've been using tap water for a while and so far I didn't have any issues.... There is no algae growth whatsoever and the temps are OK. I use it mixed with EK Pastel White fluid which AFAIK already has biocides and anti corrosives built in. So if I continue to run tap water, will anything bad happen? Thanks.

The main thing about tap water is it has additives that can leave deposits. Put a small bit of water in the bottom of a glass and let it completely evaporate, you will see a film at the bottom of the glass. That film can build up over time on the components of the loop. It won't explode your loop like Alderaan, but it's something to avoid if you can.

Basically what he said. Tap water has minerals in it that can cause build up in your loop and accelerate corrosion over time even with inhibitors. The inhibitors in coolants only last so long. Tap water also has chlorine in it which can effect how effective the EK biocides work.

You spend a lot of money on your custom loop and PC components. Don't skimp out on something cheap like distilled water.

Hope this helps.

Most important thing is that tap water conduct electricity perfectly. Because of all salts, minerals and deposits contained in every drop. If you have a leak, literally one drop is enough to fry every piece of electronics it touches.

While distilled/de-mineralized/ionized is non-conductive at first, conductivity is achieved over period of time (think 4-6 months - maintenance!). It slowly absorb ions from metal parts it touches constantly (rads, blocks, fittings). Distilled water is purest fluid you can use. But because of it's pure state is also very chemically active - absorbing all ions and salts it can find.

And I don't even mention very realistic problem of corrosion folks above mentioned.

Depending where you live could be very bad. Where I am the water is very very hard with minerals.
