What is the recommended twist when solvent welding PVC joints?

• A. 1/4 Turn
• B. 1/2 Turn
• C. 1 Turn
• D. No Twists

Answer: (A)

During solvent welding, the goal is to wet both mating surfaces evenly and seat the joint fully without disturbing the alignment. A brief, light rotation as you insert the pipe into the fitting helps spread the cement around the circumference and ensures the surfaces mate evenly. This small twist promotes complete wetting and a strong bond once the solvent cures. Twist too much, and you can squeeze excess cement out, misalign the joint, or create weak spots. Not twisting at all can leave uneven coverage and poor wetting. So the recommended approach is a short, gentle rotation during insertion to achieve consistent, full contact around the joint.
