My PetSafe® Creekside Ceramic Pet Fountain Has Low or No Flow
In the event the pump in your fountain no longer has sufficient flow, try these steps to get it working again.
Ensure the fountain is filled with water.

Ensure the gasket on the underside of the cone is lined up properly with the circle on the top of the carbon filter housing.

Remove the filter and run the fountain. If the flow improves without the filter, rinse your filter thoroughly and shake vigorously. Change your filter if it has not been changed recently. New filters can be purchased on PetSafe.com. Visit How To Replace the Carbon and Foam Filters in My PetSafe® Creekside Ceramic Pet Fountain for help with filter removal and replacement.
Disassemble and clean the pump using a 50/50 water and white vinegar solution as described in the article How To Disassemble and Clean My PetSafe® Creekside Ceramic Pet Fountain.
