1 Completely fill air chamber that needs the valve replacement.
2 Using a valve tool, loosen the valve by turning counter clockwise (Do not completely remove the valve or the boot that holds the valve to the tube will drop inside the air chamber and will be extremely hard to retrieve) and place back over the valve patch.
3 Deflate the tube. Press against the material to hold the boot on the inside of the air chamber. Unscrew the valve the rest of the way and remove. Screw the new valve into place and achieve a “hand tight” fit.
4 Re-inflate the tube and use the valve tool to tighten the valve fully.
