You hook your water hose to the pedestal and lay the hose in the sun. As the sun heats up the hose and the water inside doesn't the pressure inside increase also ? So at the pedestal you have say 100 PSI wonder what it would be at the RV on a hot summer day?
I doubt the pressure would change much even if the hose was sealed on both ends. As things heat up the water will expand. But the hose will expand due to thermal growth too. The hose will also soften some at the higher temperature.
