Troubleshooting: Handle will not stay in the on position (one-handle faucets)
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. For models using a handle connector, a metal washer may be missing or the connector could be broken.
First, it is essential to identify the model of your faucet. Please view our Find Your Product section to determine your model.
If your faucet has a 1225 cartridge, make sure all the screws are tight.
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 your faucet has a handle connector:
- Change the handle connector.
- If the cartridge was replaced, check the old cartridge stem for a gray metal washer. This washer must be transferred to the stem of the new cartridge.
