Wow!! 14 lbs?? What in the world could make it so much heavier?

Another cool thing about it is that it's got an internal bypass that gradually flips the pressure switch which means less stress on the pressure switch and less problems.

   If you could let me know how it works.  My pump was acting up today, took me about an hour to get it working.  Thanks.
