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.
  • Use a soft damp cloth to clean the diverter rod. Do not scratch the surface of the rod.
  • Dry the diverter rod.
  • Lift the diverter knob all the way up and apply a small amount of NSF-61 certified silicone (plumber's) grease to the diverter rod.
  • Work the diverter rod up and down to coat the diverter rod and push the grease down into the seals located in the spout base.

Tip 1: Make certain that someone has not inadvertently left more than two seals on the rod (or in the spout) from a previous repair or maintenance. 

Tip 2: Try flipping the seals over. If the seals and rod have been sticky or without lubricant for too long, the leading edge of the seals may have become distorted.

Tip 3: In some cases, depending upon water pressure, the diverter will perform better if one of the two X-ring seals is removed. However, this is not an acceptable solution if water subsequently appears from the hole below the knob where the rod enters the spout.

If these procedures do not correct the problem, the K0228 Diverter Seals or K31088 Diverter Assembly should be replaced.
