Is it safe to use a garden hose for drinking water to an RV?

New pvc hoses that have water sitting in them leach lead above the recommended levels for drinking. Old pvc hoses leach some lead but not above the recommended levels for drinking. All hoses were safe to drink from if they were flushed with fresh water for a short time. So, the bottom line is flush out the hose for a minute before you use the water for cooking or drinking if the hose is new.
