I don't know if any of you all will remember, but I ordered chicken watering cups last spring. Finally set them up over the summer and wow, was it nice not to have to fill a nasty waterer every day. Well, one of the cups is leaking from a valve. Within the actual cup itself, not a pvc or joint leak. I've cleaned it out, took it apart, reassembled, and still leaking--draining a 5-gal bucket in 2 days. It's pretty annoying. To fix I'll either have to buy another cup to replace it, take it off and seal the opening, or cut the pvc pipe and make it a 2 cup system instead of a 3 cup system. Anyway, I've read of others having leaking problems with their cups, and this was used lightly for about 4 months (it's in the meatie coop, which is usually empty) and already a problem, so while I raved about them before, I'm down to a 3-star rating now. Also, the emails to the guy selling them are bouncing back, which is never a good sign for a business.
