Ok, I want to switch to a nipple system but in this heat, I am afraid I will not be able to tell if it stops working. I use a auto waterer now but I can see the water so I know it is working. I guess the question is.....How do you know if it stops working if you can not see the water. I am sure I could push the nipple to see if water comes out but I would be puttingin over 25 so I do not want to push 25 nipples. Thanks for the help. Also where can you get these cheap???? I found these but I would think the clamp would break and flood the pen.
