How to use
Measure and cut the pipe to the required run length if shorter pieces are needed, ensuring clean, square ends.

Support the pipe at regular intervals along its length according to local plumbing codes and the fitting manufacturer's recommendations to prevent sagging and maintain proper slope for drainage.

Store and handle the pipe in a manner that avoids prolonged UV exposure and mechanical damage. When joining, verify that both the pipe and fittings are free of debris, and use appropriate supports, slopes and access points to facilitate inspection and maintenance in installed systems.
