How to use

To install the insert, first ensure the water supply is turned off to prevent accidental discharge.

Usage recommendations

For optimal performance and to prevent damage to the new component, do not overtighten the handle retaining screw during reassembly. Ensure the insert is properly aligned with the valve stem before applying pressure to avoid cracking the plastic material.
