Hello, it's Stan!

If during maintenance of your Geberit built-in wall-hung toilet, you noticed that your slotted stopcock was not closing, impossible to turn, or completely blocked.

How to replace the gland on the slotted shut-off valve?

1. Turn off the water to the general.
2. Use our 8mm Allen key required for this type of repair; then unscrew the old stuffing box by turning the key clockwise. It will extract it. (Yes, the meaning is counterintuitive.)
3. When it is extracted, check that its O-ring is also removed.
4. Screw on the new gland , turning it counterclockwise . No need to squeeze extremely hard. That's it ;)
5. Finally, turn on the water to the general.

Happy repairing everyone!
