When plumbing does its job, it’s practically an invisible force in the home; all that water and other waste that is created is almost magically carried away with no fuss or inconvenience to anyone. What goes down the drain stays there.
That’s why when you notice a problem with your plumbing, it’s always a good idea to address it quickly. This is especially true if the problem you’re noticing is a bad smell. A bad smell is almost never harmless and can have a real impact on your health if you ignore it.
