I just replaced the cartridge in my Moen kitchen faucet and the handle will not stay in the on position, how do I fix this?
During manufacturing, lubrication (silicone) is used on the cartridge. The combination of lubrication and the weight of the handle can cause the faucet to self-close. This can be corrected in several ways:
If your faucet has a 1225 cartridge:
- Make sure all screws are tight.
- Remove excess silicone from center stem of cartridge.
If your faucet has a 1255 cartridge - replace the cartridge.
If your faucet has a 4000 cartridge - tighten the cartridge nut or replace the cartridge.
If the faucet has a handle connector:
- Change the handle connector.
- Check the old cartridge stem for a gray metal washer. This washer must be transferred to the stem of the new cartridge.
