K-304 Rite-Temp® Valve - Cleaning

Overview

  • Over time, your shower valve may become clogged with mineral deposits, causing an irregular flow of water. The following instructions explain how to clean the valve.

NOTE: To ensure optimal performance, Kohler Co. recommends replacing the pressure balancing unit.

NOTE: The appearance of your valve may vary, however these instructions still apply.


Remove the Pressure Balancing Unit

  • Turn off the water supply.
  • Rotate the handle to the ON position to relieve water pressure.
  • Unthread the two screws from the valve body.
  • Remove the black cap.
  • Pull out the pressure balancing unit.

Clean the Valve

  • Locate the aspirator tube at the back of the valve body.
  • Using a rag, wipe the inside of the valve body dry from residual water.
  • Using a cotton swab soaked with vinegar, remove the mineral deposits from the aspirator tube and the inside of the valve body.

NOTE: You may need to repeat this application multiple times to ensure all deposits are removed.

NOTE: Avoid using other cleaning products that may damage the valve.

  • Using a damp rag, remove any remaining deposits inside the valve body.

Reassemble the Valve

  • Install the pressure balancing unit into the valve body.

NOTE: To avoid leakage inside the wall, make sure the O-ring is properly secured around the black cap.

  • Secure the black cap onto the valve body with the two screws.
  • Turn on the water supply.
  • Rotate the handle to the ON and OFF position to check for leaks, ensuring the seals are properly secured.
