How Do I Install or Replace The Integrated Diverter For My Single Handle Tub/Shower Faucet?

This article will explain how to replace an integrated diverter for a single-handle tub/shower faucet.

To replace the diverter, you must:

1. Remove the old diverter
2. Install the seat and spring on the diverter
3. Install the new diverter
4. Test for leaks and re-install the faceplate

Please Note: Before doing any work on your faucet, please shut off the water supply for the faucet.

Once the water is turned off, you are ready to begin.

Step 1 - Remove the old diverter

1. Remove the handle, followed by the faceplate.
   
   
2. Once the faceplate has been removed, the main shower cartridge, as well as the diverter cartridge will be visible.
   
   
   
   
3. The diverter can now be removed. To do so, use a pair of adjustable pliers to remove the retainer nut. Turn counter-clockwise to remove it.
   
   
   
   If you are unable to remove it with a pair of adjustable wrenches, place a socket wrench (if you are uncertain which socket wrench size to use, identify your faucet model and contact our customer care team) on the holding bolt and unscrew counter-clockwise. If the bolt is hard to unscrew, spray some vinegar/water solution (half and half) around the bolt and let it sit for a few minutes. Afterwards, try removing the bolt again.
   
   
4. Once the retainer nut is removed, pull the diverter out of the faucet body to remove it.
   
   

Step 2- Install the seat and spring on the diverter

1. Make sure you have all of the required parts. The required parts are: (1) the diverter, (2) plastic seal, (3) rubber seat and (4) spring.
   
   
   
   
2. Insert the plastic seat into the rubber seal.
   
   
   
   
3. Insert the spring into the diverter. Note that the larger end of the spring is inserted first.
   
   
   
   
   
   
   
   
4. Install the rubber seal and plastic seat on top of the spring.
   
   

Step 3 - Install the new diverter

1. Insert the diverter into the faucet body.
   
   
   
   
2. To properly orient the diverter, rotate the cartridge until the opening at the end of the diverter matches the picture shown below.
   
   
   
   
3. Install the thin washer onto the diverter.
   
   
   
   
4. Install the retainer nut.  To avoid over-tightening the retainer nut, hand tighten it, and then use the adjustable pliers or the socket wrench to apply a quarter turn clockwise. Approximately 10-14 lbs of torque are required to properly install the retainer nut.
   
   
   
   

Step 4 -Test for leaks.

1. Once all of the parts are re-installed, turn on the water supply for the faucet and let the water run for approximately 10 minutes. If you notice that water is leaking from the diverter, tighten the retainer nut and test again.
