Corrosion problems that continue to corrode pipes usually relates to the quality of water in that house. Copper tubing is susceptible to high rates of corrosion to certain poor qualities of water. Water quality is normally related to a number of factors. You just can?t identify one factor. Most areas of the country experiencing water quality corrosion problems know their water is bad.
Pitting is also caused as a direct result of too high a velocity in many cases. Another example would be the pitting of the pipe just downstream of an elbow or a tee fitting. Again, the high velocity probably was responsible for eroding the pipe wall. In most cases, the plumber simply makes the repair. However, the same repair may be necessary in a few years. What should be included in the repair is an increase in the pipe size to reduce the velocity, or the installation of flow restrictors to limit the pipe velocity.
Here?s a site that?ll show you numerous types of corrosions on several different piping materials?
