2 – .Locate the access panel for the water lines. It will be at the same level as the shower valve, on the back side of the shower enclosure wall .  Typically, four phillips head screws will hold the access panel in place. Remove the screws and panel.

3 – Locate the two water lines. The hot should be on the right side, marked with red. The cold should be on the left side marked with blue or no mark,. If they are not marked, you should mark each line appropriately.

4 – Loosen and disconnect the two water lines from the valve. The connectors are plastic, finger knobs which should not require any tools. DO NOT drop them in the wall space.
