So my waterer is experiencing issues after the last few freeze/thaw periods. It now leaks where each nipple attaches to the PVC pipe. I tried different adhesives to address the problem, but nothing seems to be working. I'm considering the chicken fountain that some of you have purchased. Are you still happy with it? And how much assembly is required? I don't want the assembly to be extensive enough that I could compromise the integrity of the product LOL. Really curious....
