If you have an indoor water fountain, it’s important to clean it regularly. This will help keep the fountain running smoothly and prevent any water damage. To clean the fountain, first remove all of the filters. Then, use a plunger to suction onto the top of the water tank and pull until all of the liquid is removed. Pour the liquid into a bowl and set aside. Next, remove all of the parts of the fountain. Use a plunger to suction onto each part and pull until it comes off. Be careful not to damage any of the plastic or metal parts. Now, put everything back together again and test it out by using the water fountain.
