I just got my FIRST Zero G hose, have not tried it yet...
There were some on here a few months back questioning if they would work under constant pressure.. I sent an email to the company and received this response -
"Hi Joe,
Thank you for your inquiry. If you have the hose hooked up to an RV and are using a pressure regulator with it, it will work there is notice on the label that the hose is not meant to be left under pressure while unattended but in this application there is an exception.
