what is considered a plumbing emergency

Having a well-constructed plumbing system is crucial for your home, especially considering how much you rely on your plumbing every day. From handwashing to cooking, laundry and more, working plumbing is considered absolutely essential. For new construction homes, professional plumbing construction helps ensure your home functions seamlessly from top to bottom.

New Construction Plumbing Components

As a homeowner, you’ll never see the majority of your home’s plumbing. Yet, it’s good to have a basic understanding of the system and what it entails, as each component works together to create a functioning plumbing system. The main components include:


Pipes shuttle water in and out of a home, drawing water in at 50-60 psi from the water supply line. Gravity does the work of ushering the used water out into a septic tank or sanitary sewer system. With proper maintenance, well-installed pipes can last upwards of 40 years.


Faucets, tubs, sinks, drains, and showers are all examples of interior plumbing fixtures. They’re connected to the plumbing system and serve to deliver and drain water to and from the home.

Septic Tank

For homes that have a septic system, the septic tank, which is tasked with separating out liquid waste from solid waste, is housed in an underground chamber 10 to 25 feet away from the home.

The Construction Plumbing Process

Construction plumbing overlaps with the overall development process, however, there is a general step-by-step outline you can expect the plumbing installation to follow. Here’s what you can expect from the process.

Design and Planning

The plumbing contractor works with the project architect or a plumbing designer to create a plumbing plan for the home.

Permits and Regulations

The plumber will obtain the necessary permits from local authorities to ensure compliance with local building regulations.

Rough-In Stage

This is the initial phase where the main water supply and drainage lines are installed.

Fixture and Water Heater Installation

There are a lot of non-plumbing construction steps in between the plumbing rough-in and the fixture and water heater installation. Once the rough-in is complete, the water heater and fixtures are installed throughout the home and connected to the water supply and drainage lines.

Pressure Test

The plumber will conduct a pressure test of the plumbing system to identify and fix any leaks. Inspection A plumbing inspection will be scheduled and performed to ensure compliance with local codes and regulations.


In regions that experience freezing weather, the water pipes will be insulated to prevent them from freezing and bursting in the winter.

Final Inspection

Finally, a final inspection will be scheduled to ensure everything is up to code.


If necessary, the plumbing team will coordinate with landscapers to ensure outdoor plumbing, such as hose bibs, is installed.

Documentation & Education

Records of the plumbing work, including plans, permits, and inspection reports, will be provided to the homeowner. If you're the homeowner, make sure you know the location of shut-off valves and other essential plumbing features.
