I really don't think it has much to do with your bowls so much as packing and heat management techniques. Or it really could be that one small leak you have.
As far as the hose is concerned, I could see light through mine as well and it still had metal coils inside. When I ran water through it one time I saw orange water come out the other end which was clearly not from the smoke. I cut into it just for fun and there was metal coil on the inside that had completely rusted out. It wasn't solid metal, obviously, but any metal inside the hose or the handle can rust over time.
