Reliable Water Supply When Underground Lines Fail

Water Line Repair & Replacement in Salt Lake City for low pressure, leaks, and aging line failures affecting water delivery to the home

777 Contractors, LLC provides water line repair and replacement services to homeowners in Salt Lake City whose main water lines have developed leaks, lost pressure, or failed due to age, ground movement, or freezing. When you notice wet spots in the yard, a sudden drop in water pressure, or a spike in your water bill without a corresponding increase in usage, the problem often lies in the underground line that runs from the meter to your house. You need accurate diagnostics and a repair method that restores safe, consistent water delivery without unnecessary excavation or prolonged disruption.


Water line repair addresses isolated leaks or damaged sections using targeted excavation and replacement of the affected pipe segment, while full replacement is necessary when the line is galvanized steel, polybutylene, or another outdated material that has corroded internally or developed multiple weak points. The crew uses electronic leak detection equipment to pinpoint the failure without digging exploratory trenches, and coordinates with the local water district to shut off supply at the meter during installation.


If your water pressure has gradually declined, you see standing water near the meter or foundation, or you are preparing to upgrade older infrastructure before a major renovation, a water line evaluation provides a clear diagnosis and a fixed-price repair plan.

Efficient Methods That Minimize Landscape Disruption


You receive a written assessment that includes the location of the leak or failure, the condition of the existing pipe material, and the recommended repair or replacement method based on depth, distance, and site conditions. The crew marks the line path, protects landscaping with plywood walkways and tarps, and excavates only the sections necessary to access and replace damaged pipe.


After installation, you will notice stable water pressure at all fixtures, clear water without discoloration or sediment, and the absence of wet spots or erosion in the yard. 777 Contractors, LLC pressure-tests the new line to confirm it can handle normal and peak demand, flushes the system to remove debris, and backfills trenches with compacted soil to prevent settling. The new line is typically copper or high-density polyethylene, materials chosen for their resistance to corrosion and longevity in Utah soil conditions.


Water line work does not include meter replacement, interior plumbing upgrades, or irrigation system repairs, though the crew can coordinate shut-offs and scheduling to minimize inconvenience. Depth and routing are determined by local code, frost line requirements, and the need to avoid conflicts with sewer, gas, and electrical utilities.

Questions About Water Line Repair and Replacement

Homeowners in Salt Lake City want to know how to identify problems early and what the repair process involves.

How do you find a leak in an underground water line?

Electronic listening devices and pressure testing equipment isolate the leak location without digging random trenches, allowing the crew to excavate only the damaged section.

What causes water lines to fail?

Corrosion, ground movement, freezing, and poor original installation are the most common causes, with galvanized steel and polybutylene lines particularly prone to failure after twenty to thirty years.

Will my water be off during the repair?

Water is shut off at the meter during active work, but service is usually restored the same day once the new section is installed and tested.

Do you repair the landscaping after excavation?

Trenches are backfilled and graded to match the surrounding surface, but sod replacement, planting, and decorative landscape restoration are handled separately unless included in the original agreement.

Are you licensed to work on water lines in Salt Lake City?

Yes, 777 Contractors, LLC holds the required Utah contractor license and coordinates with the water district to ensure safe shut-off, compliant installation, and proper inspection before the line is placed back in service.

If you suspect a leak or want to replace an aging water line before it fails, a professional inspection and proposal give you the information needed to make a confident decision without unnecessary delay.
