It includes a step for applying primer to the pipe and fitting. Manufacturers should supply specific instructions for their particular products, if and when it seems necessary. In addition, ASTM Standard D 2665-95 contains an abbreviated procedure for solvent cementing PVC DWV joints. In case of conflicting solvent cementing instructions, the instructions of the cement manufacturer should be followed. We interpret this as not requiring the use of primer or cleaner for non-pressure applications such as drain, waste, and vent installations.
Special care is taken in the preparation of the joint.
The instructions on the cement can must be followed closely. This includes making sure the pipe and fitting surfaces are clean, the pipe and fitting have a good interference fit, and the pipe is fully bottomed out in the joint.
