How to Fix a Shower Mix Valve
- 1). Take off the hot water shower handle. There may be a screw on the end of the handle that needs to be removed before the handle will come off.
- 2). Find the large valve stem. It should be directly behind the area where you removed the handle. There will be a screw attached to the valve stem. This screw controls the shower mix valve.
- 3). Turn the screw counter-clockwise to release more hot water and clockwise to release less.
- 4). Test the valve to see if the water temperature is to your liking.
- 5). Reattach the shower handle and replace the screw that holds the handle in place.
