If this is a non-pressure balance tub or shower:

On a single-handle tub or shower, you need to tighten the adjusting ring or replace the cam and packing.

  1. Tighten the adjusting ring until no water leaks around the stem when the faucet is in the full-on hot and cold mixed position and pressure is exerted down on the handle.

  2. Loosening and tightening the adjusting ring also controls how hard or easy the handle is to use. Over tightening the adjusting ring can cause premature wear of the seal surfaces, necessitating frequent repairs.

If leak persists, you may need to replace the cam and packing using Delta Genuine Parts.

  1. Shut off water supply.

  2. Cover drain opening so parts don't fall into it.

  3. If you have a lever handle with a red and blue hot/cold button, pry it off to expose the set screw. Loosen the set screw with an Allen wrench and remove the handle. If you have a knob handle, pry off the handle button, remove the screw and lift off the handle.

  4. Unscrew the cap counterclockwise and lift off. If the cap is too difficult to unscrew by hand, loosen the gray or white adjusting ring in the cap and try again. If it is still too difficult to remove by hand, place a crescent wrench at the top of it and turn counterclockwise. To avoid damaging the faucet finish, you may want to place a jar opener gripper between the cap and wrench or a heavy cloth such as a towel between the cap and wrench.

    CAUTION: IF YOU NOTICE THE CAM TURNING ALSO, QUIT TURNING IMMEDIATELY AND CALL A PLUMBER.

  5. Remove cam, packing and ball by lifting up on ball stem.

  6. Place replacement packing and cam over stem of ball and engage tab on cam with slot in body. Push down.

  7. Partially unscrew adjusting ring and then place cap over ball stem and hand tighten onto body, while pushing down on cam to keep cam's tab engaged with slot in body.

  8. Tighten the adjusting ring until no water leaks around the stem when the faucet is in the full-on hot and cold mixed position and pressure is exerted down on the handle.

  9. Loosening and tightening the adjusting ring also controls how hard or easy the handle is to use. Over tightening the adjusting ring can cause premature wear of the seal surfaces necessitating frequent repairs.
