Step 5 · Install Fittings and New Pipe Section
Before assembly, use the permanent marker and tape measure to mark the correct insertion depth (e.g., 1 inch) on all four pipe ends (the two existing ends and the two new ends). Take one 1/2-inch push-to-connect coupling and push it onto one of the existing pipe ends with a firm, steady motion. Push until the fitting's edge meets your marker line. You will feel a distinct 'thump' or 'click' as the internal grab ring locks onto the pipe. Give it a gentle pull to confirm it's secure. Now, take your new pipe section and push it into the other end of the same fitting. Finally, slide the second coupling onto the other end of your new pipe section, and then push this assembly onto the remaining existing pipe end. You may need to slightly flex the pipes to get them aligned. Ensure all connections are pushed to the depth marks.
