Narara's rental stock is predominantly 1960s–70s brick homes with original or early
replacement toilets. Single-flush suites are well past their design life, and older
inlet valves, float mechanisms, and outlet flaps all fail over time.

Central Coast Council's water supply is fully metered. Older single-flush toilets in
Narara's 1960s–70s homes use 11–15 litres per flush. A modern 4-star WELS
dual-flush suite uses 4.5L full flush / 3L half flush — cutting toilet water
consumption by 60–70%.
