Step 4 · Mark Insertion Depth and Install Fitting
Before installing the fitting, you must know how far the pipe needs to be inserted. The push-to-connect fitting will come with a depth gauge tool, or the required depth will be printed in the instructions. Use this gauge or a tape measure to measure from the end of each pipe and make a clear mark with your permanent marker. This mark is your visual confirmation of a successful connection. Take your slip coupling and the provided disconnection clip. Push the coupling completely onto one of the pipe ends until it can't go any further. Now, place the disconnection clip on that same pipe, press it against the fitting, and slide the coupling back over the gap and onto the other pipe. Ensure it's centered over the gap. Push both ends of the pipe firmly into the fitting with a steady, even pressure and a slight twisting motion until you reach the depth marks you made earlier. You should feel a solid 'click' or 'thunk' as the pipe passes the O-ring and seats into the grab ring.
