Which of the following is true when joining PVC conduit?

When joining PVC conduit, it is crucial to avoid rotating the conduit after it has been inserted into the fitting. This is because once the PVC cement is applied and the conduit is pushed into the fitting, it begins to set and form a bond. Rotating the conduit can weaken this bond and lead to improper sealing, which could result in leaks or mechanical failure over time. The joint relies on a precise alignment and bonding surface to ensure its integrity, and any movement post-insertion can compromise these factors.

Other considerations regarding the joining process include timeliness in applying the cement and cutting techniques, but those do not take priority over the importance of maintaining the position of the conduit once it is joined.
