Copper Drain Pipe Corrosion

Pitting corrosion is the non uniform localized attack of the wall of copper tube pipe or fittings initiated on the inside surface of copper water pipes.

Copper drain pipe corrosion.

Corrosion can cause the piping to fail in some cases in less than 10 years. If there are iron pipes present the water can be colored rust or reddish and contain metallic or sulfur odors and sediment. Pinhole leaks in copper pipes can occur on both. Stagnant water allowed to sit in horizontal lengths of piping for extended periods can corrode the inside of copper pipe.

In some areas copper ions stay in solution in the tap water instead of precipitating onto the walls of. Water moving through a pipe at unusually high velocity can wear away copper from the interior of the pipe. Copper can be toxic and water containing levels over 1 0 mg l should not be used for drinking. Under these circumstances you should insulate the copper with a suitable coating.

Signs of pipe corrosion occur as early as two years post installation. Copper normally forms a protective layer along its surface guarding against corrosion and. Inspect copper piping for leaks corrosion pinholes leak risk factors identify the copper pipe type. First what quality of copper has been installed.

Copper pitting corrosion there are many forms of corrosion but pitting corrosion is most likely to culminate in pinhole leaks in copper plumbing. Some of the issues associated with corrosion in copper drain pipes include. One of the main symptoms of pipe corrosion is blue green stains on your sinks showers faucets drains and other plumbing fixtures. The copper pipe green corrosion is caused by the copper being dissolved out of the pipes and then deposited elsewhere.

A neutral or acidic ph of water dissolves the copper oxide barrier of pipes making them vulnerable to accelerated corrosion resulting in pinhole leaks. Copper piping is sold in different. Inspect both water supply pipes and copper waste pipes too.
