How do you explain ive been running nothing but distilled/R.O. in my loop for over a year and nothings in it and my Swiftech blocks are fine?

ive been running distilled water for over 6 months and its crystal clear. no additives, no kill coils, nada. just good old fashioned water.

You guys do know there are different grades of copper as well, right? And even within those grades are deviations not just from manufacturer to manufacturer but batch to batch. Then there's the water itself which varies from city to city and just day to day. You guys act like every situation should be exactly the same.

News flash people, every situation is different, that's why additives are around to make sure all of these variables have been covered.
APU what?

If distilled water was actually used, then there shouldn't really be any variables large enough to cause corrosion in 8 days. If the copper quality is actually to blame, and it varies this much from block to block, then better quality control needs to be in place.

In my opinion, there must be something else in the loop causing this to occur more rapidly. Pump housing? Fittings? Other blocks?

Do you even know what distilled/R.O. water is? LOL PURE H2O! Now, are you gonna say that atoms have different purity grades?

Ed, your brand is taking a beating. I personally believe your getting the Fox News treatment and this is being blown up like you just bought a million dollar bus. You need some deft PR handling right about now, and the type of posts you make should be less standoffish. Just my two cents.



I am with you. There was definitely an issue with EKs plating process in the past, how wide spread is unknown, but it was enough of a problem to change the plating process for EK. Now we have this new (for EK anyway) plating process, who knows how well it was implemented. Maybe there is a problem, maybe not. But its way too soon to condemn EK and say they are going to be shuttering their doors. I have been using a simple stratey with EK, don't buy nickle plated products, stick with the copper. Has worked so far. I did buy one nickle plated product, no signs of deterioration..... yet....
I have had 0 problems of anything i've bought that was ek, they all are copper <--- cause of horror stories .Except my gpu block which is en and it looks fine so far<-- Didn't have a copper one in stock.I have had other blocks/ress's that were just horrible, but op sorry if its not up to par hope they fix it or it just wipes off.

His point is that copper blocks aren't as exposed to the elements as copper outdoors...which is kind of obvious...

your right, every situation is different. kinda makes your first post pointless than right?? thought so

Distillation can only remove solids or other liquids that have a boiling point higher than what's being distilled. Oxygen is already a gas i.e. past its boiling point.
Yes however in the case of corrosion due to oxygen, it will not occur in water. Especially not with distilled water, which is for the most part de-ionized (it can't be completely de-ionized or it would turn into a gas.) Theres some scientific phenomena that occurs with copper ions and water, but I really don't remember the details:

A green layer of verdigris (copper carbonate) can often be seen on old copper constructions, such as the Statue of Liberty, the largest copper statue in the world build using repoussé and chasing.[9] Hydrogen sulfides and sulfides react with copper to form various copper sulfides on the surface. In the latter case, the copper corrodes, as is seen when copper is exposed to air containing sulfur compounds.[10] Oxygen-containing ammonia solutions give water-soluble complexes with copper, as do oxygen and hydrochloric acid to form copper chlorides and acidified hydrogen peroxide to form copper(II) salts. Copper(II) chloride and copper comproportionate to form copper(I) chloride.[11]

The copper inside the block is not what I am concerned with, nor am I concerned with the base of the block - the visible area of the waterblock with DD blocks is NOT coated with anything protective and therefore oxidizes very quickly. The inside of a DD block hardly even starts to show signs of oxidization after a year of running with distilled + kill coil - if any. See above for why that is. The base of the block really doesn't matter because oxidization doesn't really affect the thermal properties of the metal, and nobody sees that part of the block (although a lacquer coat would affect that part of the metal adversely for heat transfer properties, which is why no watercooling company lacquer coats the bottom of their waterblocks at all.)

That is my fault, I misread the post previous to mine. I saw "just good old fashioned water" and completely missed that he just said "distilled."
