Just got off the phone with Flexzilla customer service, I explained our concerns and was told that the air hose and the garden hose were the same material, but the garden hose had an extra “lower VOC liner” to make it drinking water safe. She explained they are both very SH safe/compatible, and refered me to this PVC compatibility chart. This is good enough for me, I’m gonna order the 250’ roll of 1/2”.
