i recently started switching my cages to hanging buckets with water nipples. The goal is to eventually have them all set up to auto fill. My problem is the water nipples I purchased stop working. The first one I noticed were the ELO's normally they don't pay much attention to me unless they need something or I have treats. So I checked and sure enough they weren't getting water. The brand is Harris farms and I've replaced 16 water nipples so far because they just stop working. I'm going to order a different brand but I was curious what everyone else uses.
