Should I Flush My Loop?

[Waffles!]

Hello all. I am almost done setting up my rigid tubes and when I am done, should I flush it before putting coolant in or am I fine? I already flushed my radiator with 20% white vinegar 80% distilled water, and it was 100% clean afterwards with no sediment coming out of it. I have not flushed my raystorm pro or my pump + res combo yet. Also if I do flush it with distilled water, does it have to be 100% dry or can some of the distilled water still be there when I pour my coolant in it (Thermaltake C1000 Blue) ? Thanks!

You will need to do a leak test first anyways, so fill it up with distilled water and then, if it's all ok, swap it with your coolant.

i would say better save than sorry... i think distilled water shouldnt f*ck with anything but i would let it dry

destiled water shouldn't be any problem.

I saw people doing flushing with normal water also, and there were no problems.

Non of them waitied for loop to dry out.

 

So you should be just fine using destile water and you don't have to wait for it to dry out, because your coolant is most likely mixture of distile water and something else also.

Depends what coolant you're using, cause once you top up the loop it's gonna be V.hard to get ALL of the flush fluid out with rads and blocks etc fitted. If you flushed the rads I would just go ahead and add the coolant as you run the risk of mixing or diluting (if you using coloured/pastel) etc

Just do a leak test with distilled. I run system prep in mine after builds or rebuilds for at least 24 in the loop with it running for at least 12 hours. Then I add my coolant or utopia/distilled mix.

You don't need to flush pump/res/blocks... there's no need at all to flush a new build, only leak test... but technically that does flush it. I wouldn't worry about letting it dry, but you do ideally want to get as much of the distilled out as possible. I have a siphon pump (pictured below) to great effect (via drain port), as just letting it drain still leaves quite a bit of liquid in there I find. Not that it will do any harm, but it may dilute your coolant more than you'd like.
