Installation Note
The fixed 300mm installation height must be measured directly from the internal floor of your toilet cistern to the top of the valve housing. Ensure your cistern has the appropriate vertical clearance and a bottom-entry aperture before fitting. Hand-tighten the brass nut first, then apply a quarter-turn with a spanner—do not overtighten.
