In some cases, you can let your fountain run all winter – and ice formations can make wintertime fountains incredible. You just have to make sure that the water level in the fountain stays full enough. Any ice you see is water that isn’t in the system. So, be prepared to hook up a hose or carry a bucket of water from the house.If you’re unsure whether your fountain can operate during the winter or not, sometimes it’s just a matter of testing during a cold spell. Monitor the feature carefully in case things freeze up.

1. Drain the fountain. Get all of the water out. This is ideal especially for concrete fountains and reservoirs that are above ground. Reservoirs below ground are usually OK.
2. Remove the pump. If you allow your pump to freeze, the pressure from ice can cause cracks in the casing. If you run your fountain all winter, the movement of the water can keep the pump from freezing. But if it does freeze? It can allow water into the interior of the pump where the sensitive electronics are. That can spell big trouble for your pump.
3. Store the pump. Plop the pump in a bucket of water and store it someplace that won’t freeze. Garages and basements are popular winter getaways for many fountain pumps.
4. Take cover or move out. If it’s small enough or easy to disassemble, you can move your fountain inside for the winter. Or, if the manufacturer advises it, you can leave it out and protect it with a waterproof cover.
