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
Cardiff’s 2,762 private dwellings include separate houses, 279 townhouses and semis, and 158 flats (2021 Census). Each has its own gas arrangement, so we read the meter or LPG cylinders before pricing gas work.
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 Cardiff, and take the old unit away. No-hot-water jobs are attended around the clock.
Jobs to plan for in Cardiff
We clear blocked sinks, toilets and sewers in Cardiff 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
Council’s local history lists four main collieries at Cardiff, and in 1928 the NSW Government Railway Works moved to a site near the town. The place began as Winding Creek, after the stream through the valley, then became Lymington after one of the mines. The name Cardiff was adopted in 1889 on the suggestion of a Mr Edwards, who came from Cardiff in Wales. Hunter Water owns the open section of Munibung Creek from Pendlebury Road to Gorleston Terrace in Cardiff, and it runs behind houses on Lachlan Road. If a block backs onto a creek, check where its stormwater pipes discharge.
