Frequently Asked Questions

AI
Rim blocks hang on the edge of the bowl and clean the water as it flows down during a flush. Cistern blocks are dropped into the tank, treating the water before it even enters the bowl.
While they cannot remove heavy, existing limescale deposits, many contain agents that help prevent new buildup from forming and keep the surface smoother.
Replacement depends on the brand and usage; rim blocks typically last for a few hundred flushes, while cistern tablets are often rated by weeks of use.
