I brought it on myself. Although it could have been much worse without this S8 Case and "hanging" PSU per Caselabs design.
Enter EK Dual DDC 3.2 PWM Pump
The dual pump comes assembled and I trusted the documentation saying it was ready to go so didn't take it apart to check it.
Was doing my Leak test and didn't get past the first pour before fluid poured out the bottom of the DDC's. sigh. Thank goodness the plastic on the kitchen table trapped all of the pour, and that the Power supply in this S8 case is lifted off the bottom of the case. I guess Caselabs learned a lesson or 3. Thank goodness. Again awesome purchase of a case.
Pulled the pump and unscrewed the one DDC that seemed soaked in the airholes on the bottom of 1 of the pumps. Took one look at the O-ring with pressed lines all over it every 90 degrees and flat spots...
I'm somewhat crushed. I was really looking forward to getting some Dual Titan X Witcher 3 fun on this rig soon.
I haven't checked the other pump yet but will eventually after I think about what my options are. Purchased the EK from Performance-PCS last month.
Have any of you found any easy solution for this? Or are these O-Rings common in size? Maybe Home Depot , Loews etc. I'll check EK of course.
 I see others have had the same thing with various O-rings and EK usually send some O-Rings to help out. I submittted an EK ticket just now.
[edit2] Aaand another OCN member linked new O-rings so I'm good in 2 days when they get here.
