Without solvent welding, PVC drainage pipes will not form a permanent, watertight seal. Connections relying solely on friction or pressure will inevitably separate under stress, pressure fluctuations, or ground movement. This separation creates pathways for water to escape the intended drainage system.
The creation of secure, chemically bonded joints is crucial for the integrity of any drainage system. Properly solvent-welded joints prevent leaks, which can lead to structural damage, soil erosion, and potential contamination. This method has been proven reliable over decades of use in residential, commercial, and industrial plumbing applications.
