Plumbing For New Construction
New build plumbing in Cessnock typically begins with underground stormwater and sewer connections, followed by internal pipework installation during the framing stage. This includes hot and cold water supply lines, gas lines (if required), and drainage pipework routed through walls, floors or slabs.
Subat Plumbing Services coordinates with builders to ensure rough-ins meet design specifications and local regulations. Once walls are sealed and fit-off is due, we return to install fixtures, tapware, appliances and final test points. All systems are checked for flow, pressure and safety before handover.
Our work is supported by documented service logs and access to post-install advice if needed. This process is designed to minimise disruption to the broader build while maintaining accuracy across all stages. We also manage compliance checks and liaise with authorities where applicable.
For customers building in Cessnock, this service offers a consistent and structured approach to new plumbing installation, guided by local knowledge and professional experience.
What is involved in new build plumbing?
New build plumbing involves installing all plumbing infrastructure in a property that’s under construction. This includes underground drainage systems, water supply lines, gas piping, hot water systems and stormwater connections. The process typically starts with groundwork and rough-in stages, where pipes are laid before walls and floors are sealed. Once the structure is ready, the plumber returns for the fit-off stage, installing fixtures like taps, toilets, sinks and appliances. The final step includes thorough testing of all systems to ensure everything is functional, compliant and ready for handover.
When should a plumber be booked for a new build?
A plumber should be booked early in the planning phase of a new-build project, ideally at the same time as the builder and other trades. Plumbing work is required during multiple stages of construction: initial groundwork, rough-in during framing, and final fixture installation. Early engagement helps ensure the plumbing design fits the house's layout and avoids conflicts with structural or electrical components. Delays in scheduling plumbing work can cause setbacks across other trades, so it’s important to align timelines from the beginning.
What is rough-in plumbing in new construction?
Rough-in plumbing refers to the stage where pipes are laid inside walls, floors or slabs before the surfaces are sealed up. It includes installation of water supply lines, drain-waste-vent (DWV) systems and gas lines. This step happens after framing is complete but before plastering or insulation begins. Rough-in work doesn’t include connection of taps, toilets or appliances, that comes later during fit-off. Precision during rough-in is crucial, as any errors or misalignments can lead to costly corrections later in the build.
