Flush or replace?

Am currently cooling cpu and gpu's with:-

360 Xspc +120 xspc rads.
Xspc cpu block
and D5 pump with EK xres 140

and Mayhems x1 uv blue concentrate diluted with Mayhems ulta pure water.

All tubing is being replaced and am installing 2 new waterblocks as have moved from 7950 to 290.

Am going for new:-
Xspc compression fittings (currently using barbs)
clear tubing
Mayhems White UV - pre-mixed.

Obviously do not want the white to be contaminated with blue so am pondering which is the best approach - flush out with de-ionized water or buy new cpu block + pump and res.+ rads.
Assuming that 'flushing' is best option. Drain, refill with water & run (how long?) , repeat (how many times? ) or is it repeat until no sign of blue?
 
No need to replace. You can open up the blocks to flush/scrub them. Fairly sure you can dismantle the pump as well to do the same. Just keep going until no blue comes out.

No reason why you couldn't replace it all but seems like a waste of money.

I used tap water to flush mine. Set up in bath/sink and keep res constantly filled run the pump and check the colour of expelled liquid. (Keep your loop intact but remove the res intake and aim it down the drain).

As another option you could use the Mayhems cleaning kit - seems to do a thorough job at removing the 'bits' and colouring from the system :-)

Did not know that they made one.:o

Do now :D Bought:)

n.b. thanks for both replies - do not fancy having to dismantle the blocks etc so , for now, prefer the idea of the kit. (Both are a fair bit cheaper than replacing pump+ res+ cpu block+ 2 rads :))
 
Make sure you clean it one more time than you think. I just changed from Mayhems pastel white to clear. I stripped the whole system, ran fresh tap water through the rads for 10 min, then a couple of flushes with DI, stripped and cleaned all the blocks, washed all connectors and used fresh tubing. Filled with clear and I now have cloudy water as some white must have been left from somewhere. :)
 
My GPUs blocks had white coolant before and one of my pumps had blue coolant before, now I'm running a clear coolant using both on the same loop and it is clean.

I made 10L of filtered + boiled water to flush them, then I made a loop using DI water to 2 gpu blocks, pump, a rad and an empty 5L water bottle as reservoir, left the loop running for some hours, replaced the water 3 times, after the 2nd time it was already clear but I did two times more to be safe and on the last time I left it running for 12 hours.

I have 6x 13/10mm fittings and some tube that I use only for flushing (as my actual fittings are 16/11mm)
Also if you are going to do the same, you need to use a RAD to cool the pump, otherwise it will get hot.

but if you can dismantle the blocks it would be faster and more practical, I just didn't want to do this because I had to flush all my parts anyway.

De Luxe ! Kit should be with me before the weekend - if it were DPD it would be:) but it's with Royal M/Fail 'First Class' so might not be :(.
If it is then will hopefully be sorting over the weekend - if not it will be a week later.
Will follow the instructions and let all know how it goes.

Decided that it would be sensible to get 2 litre of white pre-mixed coolant in case the first does end up contaminated - if it does not I can use the 2nd litre when I drain and re-new in about a years time:)
