It's important for homeowners to become aware of sewer line clogs as soon as possible to prevent messy and expensive malfunctions in their plumbing systems. Homeowners can seek out repair services for clogged sewer lines if they know the signs to look out for that indicate sewer line issues.

The following are a few of the most common indications that a home's sewer line system has developed a clog:

An overflowing toilet

The most direct path to the sewer lines is through the toilet. Therefore, the toilet is usually the first plumbing fixture to become affected by a clogged sewer line. While a toilet that's overflowing does not always indicate sewer line issues, repeated toilet clogs should raise some suspicions that sewer line problems are to blame.

Clogs in multiple fixtures at the same at time

If several of a home's plumbing fixtures are experiencing clogs at the same time, sewer lines are probably clogged. A main line stoppage is likely to cause the tub and shower to back up in addition to the toilet.

The tub and shower typically become clogged before sink drains because tub and shower drains sit lower than sink drains. However, sink drains also sometimes become affected by sewer line clogs. 

Plumbing fixtures acting strangely

Sometimes, the use of one plumbing fixture could cause a strange response in another plumbing fixture if there is a sewer line clog. For example, flushing the toilet could cause the tub or shower to flood with water.

When sewer line clogs occur, air can become trapped in the plumbing system and cause bubbles in the toilet. The washing machine can also be affected. When water drains out of a washing machine, it could cause the toilet, shower, or tub to overflow if there is a problem with the sewer main. 

Unpleasant smells

If a home's drains begin to smell like raw sewage, there could be a clog. It's important to investigate such strong odors right away to make sure that they don't develop into messy water backup in plumbing fixtures.

Drainage at clean-out

The sewer line clean-out is a pipe located outside a home that offers access into the sewer line. Newer homes built within the last three decades are not likely to have a sewer line clean-out.

If there is a clean-out pipe, it can begin to overflow with sewer water when there is a clog in the sewer line. Contact a company like Mike Hensley Plumbing Inc for assistance.
