Hi, Well I followed the link on making the nipple waterers. I used the 11/32 drill bit and everything went together. However water is coming in a continual leak from each nipple. Not the gasket but the metal nipple. Drip, drip, drip. Why? I am wondering if there is too much pressure on the metal nipple? (didn't drill the hole big enough?) Is there a close up picture of how to make them? Maybe I inserted them in backwards?
