Review on Tall Silo Bird Waterer Set by Melissa Jones

Built-in water seal is leaking. Flipping the tower is very messy as half the water is lost before the water lock works. I've found that manually lifting the water stop before inverting the hose results in the least amount of fluid loss, but you still want to do it over the sink. The water stopper doesn't seal well so I have to wear a towel underneath to catch the constant dripping. When he's in a cage, he works fine.
