Understanding Electrolysis in Plumbing

Electrolysis is a chemical process that occurs when two dissimilar metals are in contact with an electrically conductive fluid, such as water. When this contact takes place within a plumbing system, it creates an environment that promotes galvanic corrosion.

Galvanic corrosion is the process in which one metal corrodes at an accelerated rate when it is in contact with another metal of a different electrochemical potential. In the case of plumbing, this corrosion can result in the deterioration of pipes, fittings, and other components.

Most plumbing systems are made up of a variety of metals, such as copper, brass, and steel. When these metals come into contact, they create an electrolytic cell, with one metal acting as the anode and the other as the cathode.

The anode metal is sacrificial in nature and corrodes more rapidly, while the cathode metal is protected. The corrosion occurs due to the flow of electric current between the anode and cathode, facilitated by the conductive fluid. Over time, this corrosion weakens the pipes and can lead to leaks and other plumbing issues.

It is important to note that electrolysis is different from general corrosion that occurs due to aging or exposure to harsh chemicals. Electrolysis specifically occurs as a result of the dissimilar metals and the electrical current passing through the plumbing system.

Understanding electrolysis in plumbing is crucial because it allows you to recognize the signs of its presence, take preventive measures, and effectively address the issue before it causes significant damage to your plumbing system.
