Water, sewer & backflow
Hunter Water supplies water and sewer here, and backflow test reports are lodged with Hunter Water. What the annual backflow test involves
Fassifern has about 265 private dwellings (2021 Census), few enough that each gets its own look. The gas meter, or any LPG cylinders, settle the supply question before we quote.
Josh holds the gas licence as well as the plumbing licence, so the gas connection and the compliance certificate are part of the same job.
We repair, replace and install gas, electric, heat pump and continuous-flow hot water units in Fassifern, and take the old unit away. No-hot-water jobs are attended around the clock.
Jobs to plan for in Fassifern
We clear blocked sinks, toilets and sewers in Fassifern with the jetter or the drain machine, and put a camera down a drain that keeps blocking.
In Hunter Water’s area the owner looks after the sewer pipes up to where they join Hunter Water’s system, including the boundary trap and inspection shaft. If the inspection shaft is full or overflowing, the blockage may be in Hunter Water’s main, so call Hunter Water on 1300 657 000 (24/7) first.

Local context
Fassifern is probably named after the town of Fassifern in the Scottish Highlands, though council says by whom cannot be verified. Its station opened in 1887 as Wyee and took the present name in March 1888, and the Northumberland company’s shafts on the western side saw the first use of electricity in a northern mine. Council gives 1928 for the water supply. The draft Teralba to Toronto Climate Resilience Plan (June 2025) names Fassifern among the suburbs most vulnerable to lake level rise, so drainage and sewer connections near the shore are worth checking.
