Guide On How Long Does It Take To Install Plumbing In A New House?

You don’t want to be waiting while pipes and plumbing are installed as an eager (nearly) new homeowner, so knowing how long the roughing-in stage takes and what to expect during this construction phase is helpful.

The installation of plumbing, often known as ‘rough-in,’ usually takes 3 to 5 days. This happens during the construction of your home, so it’s helpful to know what to expect and what issues to look out for. Continue reading for a plumbing installation timeline for your next home construction project. And you’ll know the solution by the end of this piece.

When Does A New Home’s Plumbing Get Installed?

During the construction process, plumbing is installed. Plumbing must be installed before the floors and walls are installed, as these will make the installation more difficult than it needs to be. Pipes, drains and water systems, on the other hand, are installed after the final construction and roofing have been completed.

Because removing piping that is in the way of a wall or stud is both time-consuming and costly. Your plumber will know exactly where he can (and can’t) put plumbing if he waits until the frame is finished. The roof should also be built to protect the area from rain and weather.

When It Comes To Plumbing Rough-In, How Long Does It Take?

The plumbing rough-in process can take several days in some cases. While the average home building takes three to five days, various circumstances can cause the duration to be extended. Larger construction projects, such as multi-family apartment buildings, will, for example, necessitate additional time for roughing in plumbing.

Larger single-family homes with many bathrooms are in the same boat. Weather plays a significant influence as well. Any construction activity, including plumbing rough-in, can be hampered by wind and rain.

It is critical to have enough employees to accomplish the work in a timely way to reduce the time required for roughing in. Delays can also be caused by scheduling issues with other construction contracts or inspectors.

Electricians, for example, usually build the basic electrical supply lines, while plumbers do the roughing in work. If the electricians are delayed, other tasks such as pouring the foundation or getting the initial phase inspected may be delayed.

Things That Could Cause The Rough-In To Be Delayed Are Inclement Weather

Rain, snow, sleet, hail, and thunderstorms can create hazardous work environments. Contractors cannot afford to skimp on the process when laying a pipe. Construction sites can get muddy due to bad weather, making them dangerous. Because snow causes slippage, construction is not done during these times.

More Specific Requirements

If the blueprints are unclear about the exact requirements that must be met, your contractor may have delays in completing new projects. This issue arises due to a breakdown in communication among the construction and plumbing teams. To avoid this, make sure that any future contractors you hire have a copy of the designs in advance. Members of the team with clear clarity will be able to address any concerns early on.

There Are Too Many People

Large construction projects might have a lot of people working on them, which makes miscommunications more likely. With larger organizations, it’s unavoidable. Thus competent construction teams always know how to break their teams down into smaller pieces. Examine any team you hire for a large-scale project’s reviews. Should a project result in miscommunication, this check will measure its effectiveness.

Plumbing Installation Stages

The length of duration it takes to install plumbing varies based on the job’s complexity. A knock-down rebuild, for example, will very certainly have some of the essential infrastructures in place. In contrast, a new home built in the middle of nowhere will require a more detailed plan to link to local sewage lines, etc.

We offer a wide range of household services, from routine repairs to bathroom remodels and pipe relining. Still, we’re delighted to show off our industry prowess by laying out a standard plumbing installation timeline. Keep in mind that this framework is merely a suggestion.

Initial Inquiries

You’ve discovered the ideal parcel of land in Canberra; congratulations! Some questions can be asked even before a single brick is set or a concrete slab is poured. Your builder can contact local government bodies to inquire about water and sewerage connections and any special considerations. For example, will water be provided by a private main or a corporate body subdivision?

Laying The Foundation

Plumbing lines will be installed before your home begins to take shape. This is usually done in collaboration with your plumber and builder to ensure that the process is swift and painless. If you’re starting from scratch, a plumber can help you plan key aspects of your future plumbing, such as the type of pipes to use (copper or plastic), the type of hot water system you want, etc.

Backfilling Stage

Testing will be performed following your piping installation to confirm that all pipes, drains, and sewerage lines are watertight. Then, in preparation for your new home build, backfill the plot and cover your new piping network with soil. Backfilling your piping trench with trash or hard waste might harm your new underground pipes. Therefore this step is critical.

Waterproofing And Testing

Now that the hard work has been completed, it’s time to double-check that your plumbing is watertight and ready to accommodate your family’s demands. Every part of your plumbing will be tested, including the water supply, sewage, stormwater, greywater, and rainwater systems. At the end of this process, you’ll be given a certificate of compliance, which means your new house is now officially water-ready!


To conclude about How Long Does It Take To Install Plumbing In A New House? All specifications and designs, including cabinet and appliance size, layout, and placement, should be available to the HVAC contractor before scheduling. The exact placement of sinks, worktops, cabinetry, and bathtubs should also be written out on the floors and walls so that the plumber can properly install the pipes.

They should go to the construction site ahead of time to ensure they have enough space to install all necessary pipes and ductwork. If any issues are discovered, there will be enough time to change the plans. After the rough-in is finished, the general contractor should conduct a spot inspection to ensure that the joists are good.

Water lines drain; nail plates, and toilet flanges should be checked for placement. After the rough-in, the HVAC contractor should have taken care of pressure testing and final inspections. If there are no issues, the plumbing rough-in should take 3–5 days.
