Whole-House Repipe Leak Detection & Repair

A whole-house repipe in Smyrna is the correct long-term solution when a supply system has entered systemic failure rather than isolated point failure. The distinction matters because the approach is different. A single pinhole leak in an otherwise healthy copper supply system is worth repairing in place. A supply system that has produced two or three pinholes in different locations over the past few years, or pressure testing that reveals multiple simultaneous low-level leaks in the same branch circuit, has entered a failure pattern that is driven by the age and chemistry of the entire copper run, not by a single defective section.

In Smyrna, the systemic failure driver for copper supply is the combination of pipe age and soft Chattahoochee surface water chemistry. The 1960s-to-1990s copper in Walker Park, Highland Park, Argyle, and the Spring Road area has been in contact with Smyrna's soft, chloramine-treated surface water for 35 to 65 years. The corrosion pattern that develops from this combination is distributed across the pipe run rather than localized at scale deposits, which means pinholes can appear at any point along the supply circuit. Chasing individual pinholes in a system at this stage costs more in aggregate repair costs, drywall patching, and water damage over the following years than a thorough repipe.

Repipe vs. Patch: The Decision Criteria We Use

We assess each supply system honestly before recommending a repipe. The criteria that point toward repipe rather than continued patching:

• Two or more confirmed pinhole leaks in the same supply system within a 12-month period
• Pressure decay testing that reveals simultaneous pressure loss on multiple branch circuits, indicating systemic leakage rather than a single breach
• Visible external pitting corrosion on accessible copper sections, suggesting the interior pitting pattern extends through the system
• Original galvanized steel supply lines in a pre-1960 home that are producing flow restriction and joint corrosion simultaneously
• Prior repair history showing repeated copper repairs in the same home over several years

How We Repipe a Smyrna Home

The standard repipe approach in Smyrna uses PEX-A supply tubing to replace the existing copper or galvanized steel system. PEX does not pit-corrode in response to Smyrna's soft water chemistry, which eliminates the failure mode that drove the pinhole pattern. The repipe process:

• System mapping: We map the existing supply routes before cutting anything, identifying all branch runs, stub-outs, and the manifold or distribution point that serves the system.
• New routing: PEX is flexible enough to route through wall cavities and floor assemblies with minimal access openings. In Smyrna's finished basement homes, we route through the basement ceiling space rather than through the finished walls of the living levels wherever the geometry allows.
• Old system abandonment: In most cases, the old copper or galvanized supply is cut at the main and abandoned in place rather than removed. Removal of old copper from inside walls adds significant labor cost without adding plumbing performance benefit.
• Fixture reconnection: Every fixture, appliance, and shutoff valve is reconnected to the new PEX supply at the stub-out location. We pressure test the complete new system before restoring water service.

Permits and Inspections for Repiping in Smyrna

A whole-house repipe in Smyrna and Cobb County requires a plumbing permit and a final inspection by the City of Smyrna or Cobb County building department, depending on jurisdiction. We handle permit applications as part of the project scope and coordinate the inspection. The inspection confirms that the new PEX system meets Georgia Plumbing Code requirements for material, support spacing, and connection methods before we close any access openings.
