TS27 - Diverter Knob Will Not Drop

TS27 - Diverter knob will not drop

A sticking diverter is nearly always caused by one or both of:

  • Something has gotten onto the rod and/or the seals and made them sticky.
  • The lubrication has been worn or wiped away.

Clean and lubricate the diverter. If you haven't done this in a while, do not be surprised if you must do the more thorough cleaning:

  • Lift the diverter knob all the way up and hold it in that position
  • Use a damp cloth (no soap or detergent) to clean the entire exposed diverter rod. 
  • Apply a coating of NSF-61 certified silicone (plumber's) grease to the entire exposed diverter rod. WD 40 or other lubricants are not acceptable substitutes.
  • Release the diverter knob and allow it to drop.
  • Lift and drop the diverter knob several times to work the grease down into the seals in the spout.

If that does not solve the problem a more thorough cleaning and lubrication are required:
