Warning for newbies!
I was looking around at some sites that are listed in the forums around here and found one that’s got a great pumping guide. Also they have a warnings page that shows some common problems due to pumping to long at to high of a pressure, the problems that are listed are why the vets around here tell all of us newbies to keep the pressure low even if it feels great, to avoid some of these problems. I will try to put a link to the site at the bottom of the post.
