Removal of the Handle

1.  Always turn you water supplies odd before disassembling your faucet.  With the supplies turned off, move you faucets handle to the "on" position to relieve pressure.


2. Insert the 3/32” Allen wrench into the hole in the handle on the side opposite the lever. Unscrew the Allen screw only until the handle will slide off. This screw does not need to be fully removed.

Special Notes for Removing the Allen Screw
Note 1:  In some cases, accessing the hole in the handle might require loosening the faucet under the sink and rotating the body of the faucet.

Note 2: Some models may have a small round plug/cap covering the handle hole which will need to be removed before using the 3/32" Allen wrench.




3. Unscrew the handle hub to remove.

Installation of the Cartridge
