Step 5 · Mark Depth and Install Fittings

Using your marker, transfer the insertion depth measurement onto all four pipe ends: the two existing ends and both ends of your new pipe piece. Take one of the push-to-connect couplings and push it straight onto one of the existing pipe ends with a firm, steady motion until it bottoms out at the depth mark you made. You should feel it 'grab' the pipe. Repeat this for the other coupling on the other existing pipe end. Now, take your new pipe section and insert one end into one of the installed couplings. Finally, align the other end and push it firmly into the remaining coupling. Give each connection a gentle tug to ensure it is secure.
