Signs Your Main Water Line Needs to Be Replaced

A failing main water line does not always announce itself with a sudden loss of water. In Las Vegas, where older galvanized steel lines and the effects of desert soil movement are common, the signs often build gradually before a full failure.

• Low water pressure throughout the house. If every faucet and fixture has weak flow and there is no city-wide pressure issue, the main line is a likely cause. A corroding or partially collapsed pipe restricts flow before it fails completely.
• Unexplained wet spots or sinkholes in the yard. Water escaping from a buried main line saturates the soil above it. In Las Vegas yards, this often shows up as a soft or sunken area in an otherwise dry lawn.
• Discolored or rusty water. Brown or rust-colored water from every fixture at the same time points to corrosion inside the main line itself, not a fixture or water heater issue.
• A sudden spike in your water bill. If your usage has not changed but your bill has gone up significantly, water is escaping somewhere between the meter and your home.
• Complete loss of water pressure. A main line that has corroded through or separated at a joint will stop water delivery to the entire house at once.

Main Water Line Replacement: What the Job Involves

Main water line replacement means removing the failed pipe running from your water meter to the point where it enters your home and installing a new line in its place. The scope of the job depends on the length of the run, the type of existing pipe, and the condition of the soil and landscaping along the route.

Pipe Materials We Install

MG Drain Services LLC installs Wirsbo AquaPEX for main water line replacements. AquaPEX is a cross-linked polyethylene pipe that handles the pressure demands of a main line and resists the mineral buildup and corrosion that shortens the life of older galvanized and copper lines in Las Vegas hard water conditions. It is flexible enough to route around obstacles and has a long service life.

Trenching and Excavation

We excavate along the line route to expose the old pipe, remove it, and install the new line at the correct depth and slope. We backfill and compact the trench after installation. Landscaping restoration beyond basic backfill is the homeowner's responsibility unless otherwise agreed in the estimate.

Permits and Inspections

Main water line replacement in Las Vegas requires a permit. MG Drain Services LLC handles the permit process as part of the job. Work is inspected by the local authority having jurisdiction before the trench is closed.

Main Water Line Issues Specific to Las Vegas, Henderson, and North Las Vegas

The Las Vegas Valley has conditions that accelerate main water line failure more than most regions.

Hard Water Corrosion

Las Vegas has some of the hardest municipal water in the country. Galvanized steel main lines, common in homes built before the 1980s, corrode from the inside out under hard water conditions. By the time the exterior of the pipe looks fine, the interior bore may be severely restricted or compromised.

Desert Soil Movement

The caliche-heavy soil throughout the Las Vegas Valley expands and contracts with temperature and moisture changes. This movement stresses buried pipe joints over decades, causing cracks and separations that are impossible to detect without digging or a camera inspection.

Older Galvanized Lines in North Las Vegas and Central Las Vegas

Many homes in North Las Vegas and central Las Vegas were built in the 1960s and 1970s with galvanized steel water lines. These lines have a typical service life of 40 to 70 years. A home built in 1965 with its original main line is at or past the end of that range. If your home falls in this category and you are experiencing pressure issues, a line assessment is worthwhile before a failure forces the issue.

Henderson and Summerlin New Construction Lines

Newer construction in Henderson and Summerlin typically used copper or PVC main lines. These lines are not immune to failure. Copper lines develop pinhole leaks and joint failures, especially in hard water conditions. PVC joints can separate over time from soil movement. When these lines fail, we replace them with AquaPEX for a longer-lasting result.
