2. Understanding Fountain Pumps

Before we dive into troubleshooting, let’s understand the heart of your fountain—the pump itself. A fountain pump is responsible for circulating water, creating the soothing sounds and captivating visual display we love. These pumps come in various sizes and capacities, but they all work on similar principles.

When you turn on your fountain, the pump draws water from the reservoir and sends it up to the fountain head, where it cascades back down into the basin. This continuous cycle creates a mesmerizing effect. However, when problems arise, this cycle can be disrupted.

If your fountain isn’t flowing as expected, it might be due to issues with the pump. Common pump problems can disrupt your water feature’s tranquility. To troubleshoot, read our guide on common pump problems.
