Tascott's fibro cottages were built in the 1950s–60s with single-flush ceramic cistern
toilets that use 9–11 litres per flush. These are decades past their serviceable life.
Replacement parts for many of these models — particularly the flush valves and ceramic
float arms — are no longer manufactured. A running toilet in an older Tascott cottage
is almost always a signal that the whole suite should be replaced.

The right fix depends on the issue. For a running toilet, the plumber first assesses whether
repair is possible given the age and parts availability of the cistern:
Cistern flap repair swap out inlet valve or cistern flap

A full toilet suite replacement in a Tascott fibro cottage is
typically a straightforward job — single-storey, accessible floor connections, no
stacking complications. Most plumbers can complete it in a single visit.
Replacing an original single-flush toilet with a WELS 4-star dual-flush unit makes a meaningful
difference to water consumption in a Tascott home. With Brisbane Water providing the local
water supply, every litre saved counts.
