I have the Columbus aqua horizontal nipples and they do seem to be leaking! We even installed a little foam circle to help secure the connection, after one nipple leaked so bad into the coop. But we are still having leaks. Thinking of somehow attaching a drip pan underneath the bucket, but haven't quite figured out how yet.
Is the nipple itself leaking? Or is the hole in bucket leaking around the nipple? I drilled one a hole a little funny and had a drop that way but got a seal by wrapping the threads with teflon tape. You could also use silicone if you have some kicking around in the garage and you don't mind permanently attaching the nipple.
