What is different about plumbing in Darwin
Plumbing in Darwin means the wet season. Stormwater, drainage and overflow problems dominate from November to April, and the Top End’s intense rainfall overwhelms drains that would cope anywhere else. The dry season brings its own issues as clay soils shrink and shift pipes. Hot water is mostly solar or heat pump, cyclones damage roof plumbing every few years, and everything on the outside of a house corrodes in the salt and humidity.

Wet-season drainage
Stormwater and sewer surcharge problems peak in the wet, when plumbers are hardest to get.
Clay movement
Shrinking dry-season clay shifts and cracks pipework.
Corrosion
Salt and humidity attack exposed pipework, fittings and hot water units.
Freight and availability
Parts cost more and take longer; book non-urgent work in the dry.
