Gary,

If you're having trouble getting the fountain to flow, you need to take the pump apart and thoroughly clean it.

If you have the directions that came with the fountain, read them. It tells you step by step how to take it apart and clean the little rotar that makes the fountain flow. If you don't have the directions, let me know. I'll send you a PM on the instructions.

I take mine apart once a month and thoroughly clean it.
