Yeah .. .. I was reading the specs on their website, and saw that it's
only rated for about 60-70PSI @ 70degF. Not so good for this
application after all.



I'd be careful with the flex PVC. It is not pressure rated anywhere
near rigid PVC and I also wonder if it meets code for domestic water
use. There are millions of homes with well pumps plumbed without
anything special to handle stress flexing and problems like the OP had
are rare.
