Fountain Pump with Low-Water Shut-Off and Light by smartpond water gardening products.

A “smart” fountain pump that shuts-off automatically in low water conditions, utilizing new technology to eliminate pump burn-out. It is a no-brainer, but first on the market.

The pumps shut-off when the water level becomes too low and automatically resumes pumping when water is refilled to the appropriate level. Comes with or without the light. ($39.47-$59.47 at Lowe’s)
