Today as anyother day I came home and the first thing I do is fire up my system. As always I take a look around to check for any leaks before powering up.
As soon as I went around the back of my rig I noticed that the Swiftech Micro res was empty and the tubing running to the top of the 1st pump was also empty. I unpluged everything so I could move it to the dinning room table and get a better look. At first I thought that the barb seal was leaking so I removed and replaced the barb, started servicing it back up and noticed a river of green fluid running across the table.
I stopped filling and drained the loop to inspect further. As I removed the 1st pumps top barb that I had just replaced I found that the threaded portion that sticks up from the top of the pump had a small crack running down from the top and was running past the threads into the top portion of the pump top itself.
I have since taken that pump out of my loop and now am running it on only one pump. I will be ordering new pump tops soon but they won’t be made of Plexi. Looking into the Petra's or EK tops as a replacement of these OCLabs tops. The OCLabs tops have worked great for months and really perform well. But the bad thing is they are made from Plexi....

My warning to anyone running plexi anything (other than a res.) at this time or looking into WC to stay away from products that use plexi in the pumps or water blocks. The people here on TPU that have been doing WCing for many years know what they are talking about when it comes to Plexi. They are very brittle and prone to cracking at anytime for any reason.

Don’t think that it won’t happen to you as I thought... It just happened to me and it’s an awakening event..

Flame me if you like and say I don’t know anything... I'm cool with that, but don’t say you have never been warned about PLEXI in water cooling...

Thanks for listening...

Peace...

Nice crack eh!!!

sorry to hear that and i hope nothing got damaged, first time ive heard of it on the OClabs top. theyre supposed to be quite good.

that usually happens when you overtighten a fitting or use to much thread tape

extreme care shoud be taken when installing/removing fittings

Yin,

No telling when it cracked, but from the time I left for work at 6am and found my res. empty at 4pm. The system was off all day and is only turned on when I'm at it.

Good thing 13 of my 19 water connections are outside my case...
