What is a common indicator of a sewer line blockage?

A foul odor is a common indicator of a sewer line blockage because it suggests that sewage or waste is unable to flow properly through the pipes and is instead backing up into areas where it should not be. This stagnation can lead to the accumulation of gases, such as hydrogen sulfide, which give off a distinctive and unpleasant smell.

When a sewer line is blocked, not only is the wastewater unable to exit the property, but it can also cause an unpleasant buildup of odors. Homeowners often notice this odor coming from drains, toilets, or in the yard, indicating that there is a problem with the sewer system that needs addressing.

In contrast, high water pressure is usually associated with issues related to the supply lines rather than a blockage. Clear water flow suggests that the plumbing is functioning properly, as water is flowing freely without obstruction. Low water usage does not typically indicate a blockage in the sewer line either; it might relate to factors like less frequent use of plumbing fixtures or dry conditions in a household.
