North Avoca's 1,004 dwellings include a high proportion of older beach houses with original
plumbing. The suburb's C4 coastal corrosivity and high holiday-home vacancy rate create
specific toilet problems.

suite replacement typically takes 2–3 hours including disconnection,
installation, and testing.

A running toilet wastes up to 60,000 litres per year on a
metered Central Coast Council supply. Even for a holiday home, the water bill saving
from fixing a running cistern is significant. Call-out fees average $80–$150.
If your North Avoca toilet is from before 1993, upgrading to a modern dual-flush suite makes
sense on both water and cost grounds. WELS 4-star dual-flush toilets use
4.5 L / 3 L per flush compared to the old single-flush standard
of 9–11 L.
