Royal Flush Biological Cistern Blocks

Not to be confused with the decorative ‘blue’ blocks
although the same concept.

Royal Flush blue cistern blocks deliver both biological
and chemical cleaning agents as well as a blue colour
each time the flush is activated.

The water-softening and sequestering agents maintain a
clean bowl while the biological cleaning power works in
the pipes to prevent any build-up of solids and continues
working in small bore, pumped toilet systems and older
buildings where drain-runs can be problematic.
Also enhances septic tank efficiency.
