Now you can set up your very own water trough without the need for a garden hose, with this Single Recirculating Water Trough. Rather than needing a constant source of running water, this model is operated with a hand pump. This allows you to install it in a lot more different places. Both ends of the trough are connected, so that water that drains on the lower end is returned back to the pump at the high end, allowing you to keep the water going continuously. They will certainly be thrilled by how the water coming from the pump seems to be endless, just as they will be thrilled playing with the water itself.
