If your home is more that 30 years old, chances are it harbors some galvanized pipe. The water system for most modern homes are plumbed in copper. Copper isn't as expensive to install as galvanized pipe, and has better lasting quality. Hard water and time are the two major ingredients that cause galvanized pipe to corrode and leak. If the budget doesn't allow for full replacement of the galvanized material, troubled sections can be replaced using copper. Remember that copper and galvanized pipe should never come into contact with one another because they are dissimilar metals. This contact can result in a condition known as electrolysis that will speed the demise of the pipe. A dielectric union placed between the copper and the galvanized pipe will make for a safe-and-easy connection. And that's The On The House tip for today.
