Dual-flush cisterns rely on inlet valves with integrated flow restrictors and filters to regulate water fill rates, preventing excessive pressure while maintaining quiet operation. When our Master Plumber arrived at this Kelvin Grove apartment, the homeowner explained both toilets had been filling unusually slowly for nearly a year. Inspection showed the inlet valve filters were partially blocked, but access required removing the entire cistern lid assembly and disconnecting the flush mechanism to reach the concealed components. The technician carefully disassembled both units, cleaned the mineral buildup restricting flow, and checked proper valve operation before reassembly. Book S&J Plumbing for expert toilet repairs with our 10% pensioner discount and interest-free payment options. Both cisterns now fill at normal speed, restoring proper functionality without needing any replacement parts.
