Water leak in corroded copper water pipe in the plumbing under a traditional bungalow in London.


Galvanic action in plumbing is a type of corrosion that occurs when two different metals are in contact with each other in the presence of an electrolyte, such as water. When this occurs, an electrochemical reaction takes place that can cause one metal to corrode more quickly than it would on its own.

Galvanic Action in Plumbing Explained and Why It Matters for Your Home

Have you ever heard of metals corroding when they touch in water? That’s called galvanic action. It happens when two different types of metals, like copper and steel, are connected in the plumbing of your home. This can lead to faster wear and damage of your pipes over time.

To keep your home’s plumbing safe, remember to:

  1. Use Similar Materials: When joining pipes, use metals that go well together.
  2. Use Barriers: Place special fittings between different metals to prevent them from corroding.
  3. Connect Your Plumbing to the Ground: This can prevent unwanted electrical currents that cause damage.
