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
Jemena’s network distributes natural gas in Newcastle, and we confirm the connection at the property before quoting. In an older terrace we also check the existing gas fittings before a new appliance is connected to them.
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 Newcastle, and take the old unit away. No-hot-water jobs are attended around the clock.
Nearby job: Hot water replacement in Merewether
We clear blocked sinks, toilets and sewers in Newcastle 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.
Common work
Recent work
Work we have done in Newcastle.
We completed a bathroom renovation in Newcastle. The finished room has a walk-in shower, grey tile and black tapware. We did the plumbing on that renovation through to fit-off of the shower and tapware. We handle the same rough-in and fit-off work on bathroom renovations across Newcastle.
Local context
Newcastle’s Census suburb is mostly apartments: in 2021, 1,898 of its 2,046 occupied private dwellings (92.8%) were flats or apartments. The older housing is in places such as the Newcastle East heritage conservation area, where City of Newcastle’s 2024 review describes two and three storey terraces and workers’ housing from the mid-19th to early 20th centuries. In a conservation area, external and structural alterations need City of Newcastle approval, and front-elevation alterations to a contributory building are generally not allowed. Terraces share walls with their neighbours, so access for repairs is planned around the next property. We did the plumbing on a bathroom renovation here, with a walk-in shower and black tapware.
