STEP 1-8

  1. Pull stop tube off of valve body.
  2. Remove cartridge clip **(See Page 3)
  3. Place white or black twisting tool on old cartridge.
  4. Using pliers, rotate twisting tool ¼ turn.
  5. Using pliers, pull on cartridge stem.
  6. Clean empty valve with nylon brush and water
**Important** After removing cartridge, we recommend cleaning the inside of the valve body (shown below) with a soft bristled nylon brush (e.g. old toothbrush), to remove any calcium build up. After cleaning, turn on water supply lines slightly to flush clean water through the open valve. We recommend placing a bowl or cup under the valve body to redirect any water splash into the tub or stall. This will help extend the life of the cartridge. image

“What if I can’t reach my clip?”

  1. If Cartridge clip is recessed (as shown below)
  2. Remove Escutcheon plate screws.
  3. Remove Escutcheon plate and remove clip.
