What is the minimum hanger spacing for horizontal PVC pipe?

The minimum hanger spacing for horizontal PVC pipe is established based on the need to adequately support the pipe and ensure proper alignment while minimizing sag and potential damage. For standard PVC piping, the guideline specifies a spacing of 4 feet between hangers. This spacing helps in distributing the weight of the pipe evenly and prevents excessive bending or stress on the joints, which could lead to leaks or breaks over time. Proper hanger installation is vital in maintaining the integrity of plumbing systems and ensuring their longevity, making this standard an important consideration for any plumbing professional.
