How to Inspect Pipes for Corrosion — Grovetown, Georgia

Complete checklist with climate-adjusted recommendations for Grovetown, Georgia

Overview

Check for green or white deposits on copper pipes and rust on galvanized pipes. Catching corrosion early prevents leaks, low water pressure, and costly emergency repairs.

DIY FriendlyModerate~30 min

Step-by-Step Guide

1

Identify your pipe material

Locate exposed pipes in the basement, crawl space, utility room, and under sinks. Copper pipes are reddish-brown and develop green patina. Galvanized steel pipes are dull gray and magnetic. PVC/CPVC are white or cream colored plastic. PEX is flexible and red, blue, or white. Knowing the material tells you what corrosion to look for.

2

Inspect copper pipes for patina and pitting

Look for green or blue-green deposits (verdigris) — this is copper oxidation. Small amounts of surface patina are normal, but heavy green buildup at joints or along pipe runs indicates active corrosion. Look for pinhole-sized pitting or white mineral crust, which signals galvanic corrosion where copper meets a dissimilar metal.

3

Inspect galvanized pipes for rust

Look for orange or brown rust stains, flaking, and rough bumpy surfaces. Check threaded joints carefully — these corrode first because the threading exposes bare metal. Galvanized pipes corrode from the inside out, so visible exterior rust often means significant interior buildup that restricts water flow.

4

Check for dissimilar metal connections

Where copper meets galvanized steel (common in older homes with partial upgrades), galvanic corrosion accelerates dramatically. Look for a dielectric union or brass fitting between the two metals. If copper is connected directly to galvanized, this is a problem that needs a plumber to install proper transition fittings.

5

Examine joints, elbows, and valves

Corrosion concentrates at fittings, solder joints, and valves where water turbulence is highest. Run your finger under each joint and check for moisture, mineral deposits, or staining on the wall or ceiling below. Even a damp fitting that is not actively dripping is a warning sign.

6

Check water pressure and color

Turn on the cold water at a faucet far from the main line. Low pressure can indicate interior pipe corrosion restricting flow. After the water has been off for several hours, check for rusty or discolored water when you first turn it on — this indicates interior pipe degradation.

7

Document and photograph findings

Take close-up photos of any corrosion, deposits, or staining you find. Note the location (e.g., 'basement ceiling, 3 feet from water heater'). This documentation helps a plumber assess the situation and gives you a baseline to compare against in future inspections.

What You'll Need

Tools

  • - Flashlight
  • - Phone or camera for documentation
  • - Magnet (to distinguish galvanized from copper)
  • - Paper towels or white rags

Cost Estimates

Professional Cost

$150 - $500 (inspection and spot repair); $4,000 - $15,000 (full repipe)

Safety Tips

  • Do not scrape or aggressively clean corroded pipe joints — you may break through weakened pipe walls and create a leak.
  • Wear safety glasses when inspecting pipes overhead in basements or crawl spaces — corrosion flakes can fall into your eyes.
  • If you find active dripping, place a bucket beneath it and call a plumber rather than attempting a repair on corroded pipe.
  • Be cautious in crawl spaces — check for pests, mold, and unstable footing before entering.

When to Call a Professional

Call a plumber if you find active leaks, extensive green buildup on copper joints, rust that has eaten through galvanized pipe walls, direct copper-to-galvanized connections without dielectric unions, or persistently rusty water. Homes with galvanized pipes over 50 years old should be evaluated for full repipe.

Pro Tip

If your home was built before 1960 and still has original galvanized pipes, plan for a repipe within the next 5 years even if there are no visible leaks. Interior buildup in old galvanized pipes drastically reduces water pressure and water quality, and burst failures are common.

Common Mistakes to Avoid

  • Assuming green patina on copper is purely cosmetic — heavy deposits indicate active corrosion.
  • Ignoring low water pressure as 'normal' when it is actually corroded pipes restricting flow.
  • Scraping corroded joints aggressively and puncturing weakened pipe walls.
  • Only inspecting visible pipes and neglecting crawl spaces, behind walls, and above ceilings.
  • Not checking for dissimilar metal connections, which cause accelerated galvanic corrosion.
