My Stylus toilet is constantly running from the cistern into the bowl. I am wasting water! How do I fix this

you'll probably find the seals failed on the flush valve.

Take lid off cistern and adjust water inlet mechanism to produce a lower level.

Operate the flush mechanism and observe the moving parts that shut the water off. Often just need to turn a nylon screw inwards towards the inlet valve. then tighten the locking nut to stop it moving,

Good luck...
