Hi, I had my tube for about seven months when Radiology found out. They found out because I caught it in a laundry basket and had to go in the next day and get a new one.I pulled it almost the whole way out I pushed it back in again! If I had been using it for food I would have had to be in the same day. They threw a fit! No one told me I had to replace it every 3 months. They say stomach acids work on it and it is better to have it replaced. If your food is running that slow you should call and ask about replacement. When I talked to the nurse about my new type of tube, she said, and it will have to be replaced every 3 months, so I guess this is standard to keep them in good condition.If there is anyone who has not seen an old one they are "black" on the end that is in your stomach.PS; I have always liked a slow drip, I try to make it a relaxing time like I would a normal meal, you guys are in too big a hurry!
