Leak in Copper Water Pipe? Here Are the Possible Causes

Mississauga Plumber

Copper pipes are actually designed to last for as long as 25 years. But like all metal pipes, copper can also corrode over time and cause leaky pipes. Here are the likely causes of corrosion of your copper pipes.Copper still remains the most popular material for water pipes because it is easy to use, it resists corrosion and it cannot be permeated by gases and liquids.Here are the most common causes of leaks in copper water pipes.

Pitting due to hard water

Hard water will cause corrosion in copper pipes and this type of pitting is more often associated with cold hard water.

Water velocity

The copper pipe can get eroded at areas where turbulence develops, such as when water changes direction suddenly, as is the case at sharp elbows and turns. If the distribution lines are not large enough, the copper pipe may get eroded quickly when the circulation pumps are oversized and the system is improperly balanced.

pH value of the water

If the pH value of water is more than 8, copper oxide will begin to form on the walls of the pipe. This film will act as a barrier and resist corrosion. But if the pH falls below 8, this film will be dissolved, leaving the copper exposed to corrosive action. As the wall weakens, pin hole leaks will begin to form.

Oxygen

Oxygen is dissolved in water to the extent of nearly 30%. Oxygen will react with metals by an electro chemical process and convert the metal into an oxide. This weakens the pipe. The rust like substance deposits in the pipes and slows down the flow of water, requiring repair. This type of corrosion is more in the presence of hot water.
