Spiral hose can turn corners without kinking and therefore not reducing flow. Flexible, but almost crush proof - Underground or above. UV protected. Not suitable for high pressure pumps, but perfect for pond pumps.

All pond, filter and water feature setups
What we liked:
Much better than PVC or rigid pipe as flexible hose allows for large smooth curves which don't restrict the flow as much as 90 degree elbows.
Less than ideal:
Nothing at all, our recommendation for all pond and water feature setups.
