inflator leaking

Just got my Mares XR jacket back from service (a certified service center) - but I see that the bladder isn't holding the air when I fill it by lung and mouth. The air is leaking through the medium pressure connection. Pushing / wiggling the inflate button with very gentle force to the side...

There are many old threads so this one includes a fix since the others may have missed where one of the leaks were actually coming from. https://www.scubaboard.com/community/search/32916521/?q=Si+tech+inflator+leaking&t=post&o=date The o-rings are 008 (qty 2), 009 (qty 1), and 117 (qty 1)...
