Yes, PVC pipes typically need to be buried to protect them from physical damage and UV exposure, which can weaken the plastic over time. When burying PVC, ensure it's placed below the frost line in your area to prevent freezing and cracking. Trench depth should be at least 12 inches for safer, long-term utility. For added protection, consider bedding with sand or pea gravel, which provides stability and prevents soil movement. Always check local building codes for specific guidelines on depth and installation requirements.
