Review on 🐶 Efficient Automatic Dog Waterer & Cattle Water Bowl: MODUODUO Livestock Watering Equipment by Elizabeth Carey

Three out of four failed. Worked for the summer. They were shut down and drained for the winter. When they were put back into service, the pressure valve on three fell out and would not screw back on. They were drained by releasing them from the bowl after draining the pipes. They're in a warm shed where the pipes don't freeze, but they're in the outside wall, so we shut down and drain all the pipes overnight. Each car water has its own shut off valve and they have been drained all winter.
