    Water supply valves need not be shut off. Remove lime and calcium deposits prior to disassembly. Use white vinegar or a commercially available product. Use NSF-61 certified silicone grease to lubricate all O-rings, X-rings, threads and moving parts before reassembly.

    These repairs do not need to be made in one session. Please note the instructions in BOLD Print along the way if you choose to break the repairs into multiple sessions.

    Install Cover except handles

    • With spout pointing straight forward, set tank onto faucet.
    • Attach plastic tube with spring to front of tank.
    • Place hose with retaining clips in the cover slot.
    • Place cover with faceplate on the faucet.
    • Screw cover retaining rings onto the faucet - coat both internal and external threads with NSF-61 certified silicone grease before attaching - hand tighten ONLY.
    Replace Handles
    • These instructions are for the hot side. Cold side instructions are in parenthesis ( )
    • With the lever at the 6:00 o’clock position, push the handle straight onto the stem.
    • Rotate the handle counter-clockwise (clockwise for cold) until water flows.
    • Slowly rotate the handle clockwise (counter-clockwise for cold) until the water just stops flowing. Do NOT over tighten.
    • Without rotating the handle, pull the handle straight off the stem.
    • While the handle is still pulled off, rotate the handle to place the lever in the 9 o'clock position (3 o'clock for cold)
    • Push the handle straight onto the stem to fully engage the knurls.
    • Replace the screw.
    • If water drips from spout, see Adjust Handles procedure.

    Adjust Handles

    • These instructions are for the hot side. Cold side instructions are in parenthesis ( )
    • Check the temperature of the water that is dripping from the spout to determine whether it is the hot or cold handle that needs adjusted.
    • Remove the screw from the handle.
    • Turn the handle clockwise to the 9:00 o'clock closed position (counter-clockwise to 3 o'clock for cold)
    • Without rotating the handle, pull the handle straight off the stem.
    • While the handle is still pulled off, rotate the handle counter-clockwise one notch (clockwise for cold) - one notch only. Do NOT over tighten.
    • Push the handle straight onto the stem to fully engage the knurls.
    • Turn the handle clockwise to the closed position (counter-clockwise for cold)
    • Reinstall the screw.

    If the drip has slowed but not stopped, repeat the procedure or check to see if it is the other side that is causing the drip.

    Follow this procedure anytime in the future that a drip from the spout develops.  Being careful to NOT over tighten the stems will greatly extend the life of the bibb washers.
