Problem: Slow Trickle of Water Caused by Loss of Water Pressure.

If you feel an unexpected change in your shower’s water pressure, it may be caused by the wear and tear on the shower valve’s internal components.

This is the step-by-step procedure on how you can calibrate your thermostatic shower valve.


  • 2.5 mm hex Allen wrench

1. To adjust the flow of temperature, you need to remove the temperature control handle. Remove the plastic cap from the bottom of the temperature control handle. Poke the grub screw using the Allen key provided with your shower and loosen it gently. Then remove the control handle. If you don’t have one, use a 2.5 mm hex Allen wrench or driver.

2. Turn on your shower and let it reach its maximum temperature.

3. For you to reach the maximum temperature, gently place the control handle loosely onto the spindle and turn it counterclockwise at least for a quarter turn.

4. Wait until the temperature regulates. In the instance that the water is still too cold, proceed by turning the spindle another quarter turn counterclockwise until you reach your preferred temperature.

5. Once you achieve the temperature you want, turn off your shower and place the control handle back onto the spindle. Make sure that the lock of the handle fits snuggly to the lock of the spindle. This will ensure that you can turn the handle counterclockwise without pressing the override button.

6. Insert the grub screw back using the Allen wrench and put back the plastic cap.

7. Turn on your shower and test if your calibration has been successful.

Reminder: If you want to make your water colder, all you have to do is follow the same steps, but you should turn the spindle in a clockwise motion.

Each quarter of a turn is equivalent to a 4 ̊F – 16 ̊F change in temperature.
