title_body: My Handpresso got leakage after leave it with some air pressure built in. Could it be worse?
upvoted_answer: Pressure may have built up as a consequence of the residual water and such inside the device and environmental temperature/pressure changes.
  
  It should be okay, and it seems to still be working. Make sure you thoroughly clean it just because you left it for a couple of days. Other than checking for any visible deformities (especially around the silicone sealed areas), if its still working it and tastes fine it likely is not broken.
