Your plumbing system is one of the most important ones in your home. You rely on it all the time, for all kinds of tasks, so you should put some effort into making sure that it stays in good shape. Part of doing that, as with all systems, is being able to detect problems as early as possible. Quicker detection means faster repairs, which saves you money and extends the effective lifespan of your plumbing system.
Unfortunately, it can be tough to reliably detect issues with your plumbing system before significant damage is done. Most of the plumbing is hidden, and the problems that commonly effect it are often subtle at first. If you know what to look for, though, you can still catch issues early enough to make a difference.
