Although preventable, pinhole leak problems are common on piping systems. These problems cause distress to residents, owners, managers and on-site personnel as well as being very costly.
The exact cause(s) of leak problems can vary. Many leak problems are caused by corrosive conditions created by hot water circulating systems. Different forms of pitting corrosion can affect cold and hot water piping. In some cases even newly repiped systems can deteriorate in a surprisingly short period of time.
Water-related problems can be quickly addressed with the proper installation of potable water corrosion inhibitors. Our systems routinely solve ongoing pinhole leak problems on plumbing systems. Even buildings with historically severe leak problems can be remedied without disruption to residents.
Before & After
The pipe in the "before" image shows the typical corrosion occuring on a hot water circulating system, bare red exposed unprotected copper. The pipe in the "after" image shows the results after water treatment inhibitors. The thin film deposit indicates that the corrosion has stopped. In many cases we can reduce the leak frequency to near zero in only a few months.
How It Works
Leak Control Systems products are food-grade corrosion and scale inhibitors. More specifically, Leak Control Systems products work by one or more of the following: general film precipitation that isolates the metal from the aqueous environment (see "Before" and "After" image), and passivation of the anodic or cathodic sites.
Note: The product is effective in areas suspected of velocity-induced errosion corrosion, see "Before" and "After" image . Scale inhibition is achieved by sequestering mineral compounds.
There are many case histories which prove the effectiveness of a well designed corrosion control system. After installation of the corrosion control system, there is an immediate reduction in leaks, followed by a decreasing frequency of future leaks, see "Typical Results" chart. Notice that without protection, the leak frequency will increase at a higher rate causing havoc to management, residents, and NOI.
