A plumbing technician is inspecting a recently completed installation of 2-inch (50 mm) ABS DWV pipe and notices several joints where the solvent cement appears to have been applied too sparingly, resulting in visible gaps at the pipe-fitting interface. What is the most likely long-term consequence of these improperly joined sections?

Question: A plumbing technician is inspecting a recently completed installation of 2-inch (50 mm) ABS DWV pipe and notices several joints where the solvent cement appears to have been applied too sparingly, resulting in visible gaps at the pipe-fitting interface. What is the most likely long-term consequence of these improperly joined sections?

Answer options:

• Increased flow velocity due to reduced friction ✅ Potential for leaks and sewer gas escape
• Diminished structural integrity of the pipe due to material degradation
• Excessive noise transmission through the drainage system

Correct answer: Potential for leaks and sewer gas escape

Explanation: Insufficient solvent cement application on ABS joints creates weak and incomplete chemical bonds, which will compromise the watertight and airtight seals, leading to potential leaks and the escape of hazardous sewer gases. It does not primarily affect flow velocity, structural integrity in terms of breaking the pipe material, or noise transmission.
