You have to install plumbing when you are thinking about building a new home or any type of establishment. And before moving on, there are certain stages that need to be completed, as with so many areas of construction or renovation.


Today we will talk about different plumbing stages in a new-home development. Generally, plumbing comes in 3 stages. These are:-


  1. Underground rough-in phase
  2. Aboveground rough-in phase (top-out or stack-out)
  3. Finishing phase (Trim-out or trim finish)



  1. Underground rough-in phase

When the groundwork can be done, there are two points in new home construction.


– The groundwork can be inspected, installed, and buried when the walls are poured into the basement.

– And the rest of the rough-in plumbing at the same time. To make sure this is doable, you need to check with the city.


From the public utilities to established building system, usually, a plumber locates all the supplies during the underground rough-in phase. This system ensure whether all the system will enter the building or leave.


This makes the future, basement bathrooms and drains will be hooked up to the main service. Furthermore, where the meter will eventually be placed, the main water line needs to be brought from the service to the area.


  1. Aboveground rough-in phase (top-out or stack-out)

The rough-in plumbing can be part of the groundwork stage that we have mentioned above. But remember, this is not always right. In the above-ground rough-in phase stage, you may need to install the drains plus vent pipes at the same time as the water lines as well.


Additionally, you need to install the shower bases, showers, and bathtubs that you are going to use. Regardless of whether you are building a new home or not, renovating your house or basement development is what always needs to be done properly.


A plumber needs to do many things during the aboveground rough-in phase. For instance:-


  1. For connection to the fixtures, a plumber needs to cut holes in the ceiling, floor, or holes.
  2. For the building’s various waste or supply systems, a plumber needs to install the pipe.
  3. To join pipe runs or any special chemical for plastic pipes, the building needs soldering equipment or welding tools.
  4. Install power tools, threading machines, propane torches, or any important power tools that need to be installed.


Keep in mind that you will need to install all of your gas lines before the drywall can be put up. And in the plumbing stage, this is always the most essential part. So, before hiring a plumber, make sure to check out if the plumber has a gas ticket or else he cannot install it. Additionally, the plumber should check everything properly before starting work.


  1. Finishing phase (Trim-out or trim finish)

And in the finishing phase, a plumber would install toilet appliances, showers, or sinks, water heaters, water purification systems, and so on. Also, in this stage, the other gas appliances and hooking up the fireplaces need to be installed.


The plumber should check out each appliance to see if they are working properly or not once each fixture has been installed.



No matter how well the plumbing systems are installed, these need to be maintained periodically. And you can say that maintenance is the fourth stage in plumbing services. However, a plumber provides various tasks, and some of them are:-


  1. Inspect the lubrication level in the meters and pumps.
  2. Repair any faulty components or fixtures.
  3. A plumber needs to verify the operating system.
  4. Regulation of the usage rate and water flow.
