It's a manufacturing fault. Speak with them and ask/demand a replacement. I had 2 do the same thing and both were replaced.
I would expect them to pay to send out the new one at their cost. If they want the old one back then they should pay for it too.
I don't think it is a gasket issue as there is an o'ring that seals it. Seems to be the actual housings that are warped.
