Installation and maintenance requirements can significantly impact piping material selection for irrigation and HVAC systems. For example, piping materials that are difficult to install or require specialized tools may increase labor costs and project timelines. Similarly, materials that require frequent maintenance or replacement may increase ongoing costs and downtime. Piping materials like PVC and PE are often preferred for irrigation systems due to their ease of installation and low maintenance requirements, while materials like copper and steel may be preferred for HVAC systems due to their high performance and durability.
