Why Is Underground Copper Piping Such a Big Problem for Homeowners?

Exposed, leaking copper pipe.

If you're a homeowner in Ada, Oklahoma, or the surrounding areas, you may have heard plumbers talk about the risks associated with underground copper piping. While copper has long been a popular material for plumbing due to its durability and resistance to corrosion, underground copper pipes can pose major problems—especially as they age.

In this article, the Ada plumbing experts at Diamond Plumbing explain why underground copper piping is such a big concern and what you can do to protect your home and wallet.

Common Issues with Underground Copper Piping

1. Corrosion Over Time

Even though copper is corrosion-resistant, it’s not immune—especially when buried underground. Soil composition, moisture levels, and even electrochemical reactions can speed up the corrosion process. Over time, this corrosion can cause pinhole leaks or full pipe failures, leading to water damage, higher water bills, and costly repairs.

2. Hard Water Accelerates Damage

Ada and many parts of Oklahoma are known for hard water. The high mineral content can cause scale buildup inside copper pipes and increase the rate of internal corrosion. This is particularly problematic for underground lines, where leaks may go unnoticed for months.

3. Difficult to Detect Leaks

Unlike visible plumbing, underground copper pipes make it hard to detect problems early. A small leak underground may not show signs until it becomes a major issue. If you notice unusually high water bills, soggy areas in your yard, or reduced water pressure, you may have an underground leak that requires immediate attention.

4. Costly Repairs and Property Disruption

Repairing underground copper piping often involves digging up landscaping, driveways, or sidewalks. This makes repairs both costly and invasive. In many cases, homeowners are shocked to discover that a hidden leak has caused extensive damage to their property—before they ever saw a sign of trouble.

5. Shorter Lifespan Than Expected

While copper pipes are often advertised to last 50+ years, many homeowners find underground copper piping fails much sooner. Environmental conditions, water chemistry, and installation practices all play a role in shortening their life expectancy.

What Are the Alternatives to Underground Copper Piping?

Many homeowners are now choosing PEX piping or HDPE (high-density polyethylene) for underground applications. These modern materials are more flexible, resistant to corrosion, and easier to install without the need for extensive trenching.

At Diamond Plumbing, we often recommend replacing problematic copper lines with more durable alternatives that are better suited for Oklahoma's soil and water conditions.
