How to Tell if a Dallas Home Has Galvanized Pipes

Quick checks

• Look at pipe entering the water heater and under sinks
• Scratch test: galvanized shows silver-gray; copper shows bright orange
• Magnet test: sticks to galvanized, not copper, PEX or CPVC
• Threaded fittings rather than soldered joints

The service line

DWU is identifying service line materials as part of the Lead and Copper Rule and asks owners to report what they find (DWU brochure). See the Dallas service line inventory.
