If the tap begins to leak when the valve is shut off, it may be time to replace the internal seal using one of the spares provided.
Turn off the water supply to the kitchen or bathroom before beginning.
Using an adjustable wrench, carefully unscrew the large hex nut surrounding the valve handle axis.
While doing this, hold the valve body firmly to avoid putting stress on or damaging the tap.
Once the cartridge is removed, replace the worn rubber seal with a new one.
Reinsert the cartridge slowly and tighten gently—do not over-tighten. Keep holding the valve body firmly during this step.
The valve handle should be in the “on” position when you screw the cartridge back in.
Tip: To extend the life of the rubber seal, always close the valve gently—just until the water stops flowing. Avoid using excessive force.
