- Choosing the Right Hose Choosing the right size and length water-garden hose is important to ensure efficient water flow for your pump, water feature, and filter systems. Determine the hose size by its diameter, which can range from 1/2 inch to 3/4 inch. Check the pump’s specifications to find the recommended hose size for optimal performance. Measure the distance between the pump and water feature or filter system to determine the length of hose needed, keeping in mind any twists or turns in the hose. Choose a high-quality, durable material that matches your specific needs and budget. By following these simple steps, you’ll be able to select the perfect water-garden hose for your setup.
