Why does copper drain and vent lines corrode? Copper pipes can corrode internally from water, just like cast iron drain lines. As water passes, the oxygen in H20 actually takes some electrons from the metal which creates corrosion. Over time, the corrosion degrades the metal which can eventually create a hole through the pipe itself.
What causes copper drain pipes to corrode? Common issues that cause corrosion include a high level of dissolved oxygen (called oxygen corrosion), pipes that were not installed correctly, improper electrical grounding, high flow rates, and a lot of sediment in the water.
What corrodes copper drain pipes? The presence of oxidizing acids; heavy-metal salts, sulfur, and ammonia; and a number of sulfur and ammonia compounds can cause corrosion to set in.
