Pipes That Don’t Match
To a DIYer, pipes may look pretty much the same, so finding a size and shape that fits might take precedence over matching pipe materials. In newer homes, this isn’t necessarily a problem, but in older homes, it is often necessary to transition from older pipe materials to the pipe materials used in modern construction. A common DIY mistake occurs when well-meaning homeowners connect zinc-galvanized steel pipes with copper fittings. Of course, a professional knows that the combination of these two materials will create a corrosive chemical reaction that will cause the connection to leak leading to water supply problems and moisture damage.
