Hey Charlie, since the PSI rating of most water lines and water pumps in RVs is usually right around 45 psi I would recommend staying under that when using the Camco RV Water Line Blow-Out Plug # CAM36153 and everything would be fine. I would probably just use 30 psi though.

Hey Charlie, how did things go using about 30 psi with the Camco water line blow-out plug? Your results could help others figure out the best pressure for winterizing their RV lines.
