I may have to respectfully disagree with you on this one Tom.  I had a PEG for 9 months and never had an ounce of trouble with it, so it was obviously installed properly.  If I was sitting in a chair or standing and I opened the end, the amount and time I had "eaten" last would determine if anything came out. If I were lying flat, usually nothing would come out even if I had just eaten.  I never reclined to use the tube, I did it wherever I was at the time.  In the car, cooking dinner in the kitchen, on the computer, etc.  I plugged in the syringe, poured the food in the syringe and waited for it to go in.  It got so I could put a can in my tube in under 5 minutes.  I'm not suggesting this style to anyone, I hate to sit still so do most things on the go.  But, I don't want everyone whose tube may leak to worry or wonder if it's installed properly.
Take care,
Minnie
