Want More Nipples On Your Waterer? You Can add More
All you'll need for installing the watering nipple is an 5/16 of 11/32 drill bit. Drill a hole up from the bottom of the container. The nipple easily screws right into your container with the help of the black installation bit. You want to leave 2-3 threads showing, no need for you to screw them in all the way.
