First, I am sure you are asking what exactly is electrolysis in copper pipes?

Here is the technical definition:

Electrolysis is defined as “a method of using a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially highly important as a stage in the separation of elements from naturally occurring sources”.

How does electrolysis occur?

Electrolysis can occur when a direct current electrical leak takes place underground, this type of leak is prone to attacking copper pipe. Electrolysis can also occur when two dissimilar metals come in contact with each other. For example, if you have had a repair on your main water line and the plumber used a new brass pipe to connect to the existing galvanized pipe, this may cause electrolysis resulting in a damaged water line.

High levels of chlorine and stagnant water are two causes of copper corrosion that can work together to accelerate deterioration. Stagnant water with low oxygen and high bacterial content is known to cause copper corrosion, and inactive plumbing systems are also vulnerable.

Some signs of electrolysis are an abnormal odor, green tinted staining on the pipe and corrosion which one may not become aware of as the piping is located below ground level.

How to fix the problem.

Plastic piping can be used to prevent electrolysis from occurring on your water line. The waterline will be inserted through a clear plastic pipe in addition to a special insulating wrap which will protect portions of the main that may still be exposed.

If you suspect that you may have electrolysis occurring in your pipes please give ASI plumbing a call!
