Connect New Water Where You Need It

Professional water line installation services in Marble Falls, Texas

Adding a garage apartment, installing an irrigation system, or running water to an outdoor kitchen requires a new water line that connects to your existing supply. In Marble Falls, new construction and property improvements often call for outdoor water lines that can handle freeze exposure, soil movement, and long-term demand without leaking or losing pressure. You need a line that meets code, fits your layout, and delivers water reliably from day one.


Marble Falls Plumbing LLC installs new outdoor water lines using proper trenching, pipe placement, and code-compliant fittings. The work supports additions, irrigation systems, and exterior fixtures such as hose bibs or pool fills. Installations are designed for freeze resistance and long-term durability, with materials chosen to match soil conditions and usage demands in Marble Falls.

How a new water line gets installed

The installation begins with mapping the route from your existing supply to the new fixture or structure. The crew digs a trench at the required depth, lays the pipe with proper slope and support, and connects it to your main line using a tee fitting or valve. In Marble Falls, trenches are dug below the frost line when possible and backfilled with compacted soil to prevent settling.


Once the line is in place and tested for leaks, you will have a functioning water supply that delivers consistent pressure to your new location. The connection is permanent, code-compliant, and ready for daily use without risk of freezing or failure under normal conditions.


The installation does not include interior plumbing, fixture mounting, or landscaping restoration beyond basic backfill. If your project requires a meter upgrade or pressure adjustment, that work is handled separately and coordinated with your local utility.

Common concerns before starting the work

Homeowners in Marble Falls often ask about depth requirements, material choices, and whether permits are needed for new water lines.


  • What type of pipe is used for outdoor water lines? Most installations use PEX or HDPE pipe, which resists freeze damage and handles soil movement better than rigid materials. The choice depends on your soil type, depth, and intended use.
  • How deep does the trench need to be? Trenches are typically dug between 18 and 24 inches deep to protect the line from freezing and surface damage. In Marble Falls, depth may vary based on local code and the location of existing utilities.
  • Do I need a permit to install a new water line? Most municipalities require a permit for new outdoor water line installations. Marble Falls Plumbing LLC can help coordinate permit applications and inspections as part of the installation process.
  • How long does it take to install a new water line? A typical installation is completed in one day, depending on the length of the run and site conditions. You will have water service to the new location once the line is tested and the trench is backfilled.
  • Can you connect the line to an irrigation system or outdoor fixture? Yes, the installation includes the connection point where your fixture or system will tie in. If you need the fixture itself installed, that work can be scheduled as part of the same project or handled separately.
