A: We also sell the replacement filters online. If you have any questions, please feel free to find us. Q: How can I judge the water level in the drinking fountain? A: The red buoy represents the water level. The more red buoys are exposed, the more water in the fountain, and the less red buoys are exposed, the less water in the fountain. When you can't see the red buoy, you need to add water to the cat water dispenser. Q: What should I pay attention to about the pump? A: Firstly, the pump should be cleaned every 2 week; then if the water level in the tank is too low, the water pump still keeps running and prone to fail. Please add water to the water tank in time.
