Water to the water fountain stopped flowing Why?

There could be several things wrong with your water fountain.

1. The Pump - Remove the pump and determine whether it is pumping water from the nozzle while plugged in. If not, you have a faulty pump and need to replace it.

2. If water is flowing just follow the tubing. If no water is coming through the tube take the tube off and blow through it. It could be blocked by debris. If clear, the pump has a pressure problem and needs to be replaced.
