Kink in my tube

[ChrisZH]

So i was wondering what could cause a kink in a custom loop. I just noticed that my flow had been restricted some (thankfully didnt play any games because of school) and i have since moved it a bit and sorted the kink out. I will of course drain the loop to clean it anyways as its been close to a year now and needs to be cleaned out. But i just cant figure out why it would suddenly kink when there wasnt anything wrong before. This picture is after i moved it, but the kink was serious. Im worried something could have happened to my pump. Ive also checked for possible leaks in all places but nothing.

any Possibility of vacuum?

Well i noticed that my pump has been working harder when i looked and saw this. Not too sure as the computer was idling when on because of school work. Idk how this happened, maybe it was the kind of angle i had it at?

I think the tubes get softer when the fluid gets warm. Plus plasticizers from the tubes dissolve into the fluid (chemicals which make it flexible). That's why most soft tubes lose some of their flexibilty after they are used in a loop for a while. That weakens the material to a point where a bend which was fine for the first few days/weeks becomes a kink. It loses the flexibility required to hold up against the strain.

If there is an air tight seal of the system there is the possibility of vacuum.  If there isn’t there isn’t.

If the system is an air tight seal and there is a vacuum (which there may not be even if there is an airtight seal) a vacuum will pull in at the weakest point of a system which would apparently be there.  IF there even is a vacuum.

Heh.  I was thinking that too but I couldn’t think of a good way to put it.

A lot of PC hardware talk is rather lewd if taken out of context lmao. Even down to the reason USB has male and female ports...

I’d open the res. 

When putting the compression fitting on, did you twist the tube at all? Normally what causes the issue for me aside from a tight radius bend with thin walled tubing.
