The Hidden Danger in Your Pipes: Understanding Galvanic Corrosion
When it comes to plumbing repairs, using the wrong combination of metals can create a ticking time bomb in your pipes. At Struse Plumbing & Air, we often discover premature pipe failures caused by a destructive process called galvanic corrosion. Here’s what every homeowner needs to know about this silent threat to their plumbing system.
What is Galvanic Corrosion?
Galvanic corrosion occurs when two different metals come into contact in the presence of an electrolyte (in this case, water). One metal sacrifices itself to protect the other, leading to accelerated deterioration. Think of it like rust on steroids – except it’s happening inside your pipes where you can’t see it.
Common Problem Scenarios
DIY Repairs Gone Wrong
- Copper pipes connected directly to galvanized steel
- Brass fittings on aluminum pipes
- Steel fasteners on copper tubing
- Mixed-metal valves and connections
- Improper use of dielectric unions
High-Risk Areas
- Water heater connections
- Under-sink plumbing
- Outdoor spigots
- Main water line transitions
- Appliance hookups
The Galvanic Scale: Why Metal Choice Matters
From most noble (cathode) to least noble (anode):
- Stainless Steel (Most Protected)
- Bronze
- Copper
- Brass
- Steel
- Aluminum
- Zinc
- Magnesium (Least Protected)
The further apart two metals are on this scale, the faster corrosion occurs when they’re connected.
