Sediment in loop and res

post #1 of 6
Thread Starter 
I started a watercooling loop approximately a year ago. This past summer I finally decided to clean out the loop. At this point, the clear walls of my reservoir were nearly opaque with what I determined was some sediment.

When I initially started the loop, I wasn't aware that flushing out the rad might prevent some sediment build up down the road but, despite missing that good info, I never thought that would lead to what I was seeing. The water was super murky and, like I said, had actually stained my reservoir.

Anyways I took apart the loop and started flushing out the rad. After 24 hours I was still getting some sediment after the flush but not NEARLY as much as I originally poured out at the beginning. Anyways, I quadroopled the prescribed amount of PT nuke and restarted the loop. It's been 4 months since then and I'm beginning to see some more build up. Any ideas on what this could be from?

Flux.

If you have a Thermochill radiator, it's almost mandatory to flush it as they are known to have it caked on the inside.

It shouldn't hurt thermal performance but it will be a pain to scrub off and remove.

What'd you use to flush the rad out? If hot, scolding water didn't get everything out, try a small mixture of distilled vinegar.

If you can pull drain the loop enough and pull the RAD, you can use the regular Prestone automotive RAD flush. This will get the worse of the worse out of it. Then rise with distilled water and place back into the loop.

If you can not remove the RAD, I would recommend using a mixture of 80% distilled "White Vinegar" and 20% Distilled Water. Do NOT use any bleaches or ammonia cleaners.

When I went to flush out the loop after the first 6-month run I looked on here and found the idea for the vinegar and distilled water mixture so I did that, flushed it out profusely, leaving hot scalding water and vinegar in there overnight and then flushing it out more in the morning. I'm not running any coolant or dyes, just the standard distilled water and PT nuke.

I'm replacing the reservoir and tubing with hopes that might help as the sediment buildup is not NEARLY as bad as it originally was.

Any other advice would be greatly appreciated.
