Removing The Handle

1. Always turn your water supplies off before disassembling your faucet. With the supplies turned off, move your faucet’s handle to the “on” position to relieve pressure.

  1. Use the chart below to remove your faucet’s handle.

  4. Grab the cartridge stem with pliers and pull the cartridge out. This might move easy at first, and then require more effort. Keep pulling until it pops out.

  5. Clean the inside of the valve body with a soft bristled nylon brush (e.g. old toothbrush), to remove any calcium buildup. After cleaning, place a bowl on the open valve to redirect water flow from the valve opening into the sink. Then, turn on the water supply lines slightly to flush clean water through the open valve. After turning the water off, use a paper towel to remove excess water from inside the valve.

Installing The 1225 Cartridge

  1. Slide the new cartridge into the brass valve body. Insure the plastic ears on top of the cartridge end up located at the twelve and six o’clock positions.

  3. On the cartridge stem, locate the small notch at the end of the stem. This is on one of the flat sides. Rotate the cartridge stem so the small notch is facing forward.

Correct: Notch facing forward

Reassembling The Handle

  1. Hand tighten the retainer nut. Then use pliers to tighten another 1/8th of a turn.

  2. The bottom end of the silver lever resembles a bottle opener. When the handle is mounted, it is important this flat edge is under the ridge on the retainer nut as shown in the photo to the right.

** NOTE: Some levers will have one open side. Installation will be the same.

​​​To best accomplish this, hold the handle body over the retainer nut and push the silver lever upwards to the on position. This will allow the bottom of the silver lever to stick out from the bottom of the handle body. You will then be able to wrap this under the ridge on the retainer nut and bring the handle forward.

Note For Installing Cartridge Clip

If the cartridge clip will not go all the way in, there are two possible causes for this.  Check the following and make any corrections:


The plastic tabs of the cartridge must be positioned perfectly at the twelve and six O'clock positions.


Solution:  If the tabs are not correctly aligned, use the plastic twisting tool to rotate the cartridge and perfectly align the tabs to the twelve and six O'clock positions.


The plastic tabs of the cartridge must be at the same level or lower than the brass valve body.


Solution: If the plastic tabs are above the brass, use the plastic twisting tool to push down an the cartridge.  This evenly distributes the pressure to the cartridge shell.



Using Twisting Tool to Correct






You are all done!
