Warning Signs of Sewer Line Problems

As sewer lines are underground, they only get noticed when a significant problem occurs.

A sewer line is an essential component of the plumbing system, responsible for moving all household wastewater to the primary sewer system. However, as sewer lines are underground, they only get noticed when a significant problem occurs. Sewer line issues, like tree root intrusion, leaks, clogs, corrosion, and broken pipe, can turn messy and catastrophic when ignored. 

Fortunately, sewer line problems do not worsen suddenly. Homeowners can prevent sewer line emergencies and expensive repairs by checking for warning signs to catch problems early before they get worse. Here are some indicators of sewer line problems:

Water back-up

Water backing up in the toilet or sink is a common sign problem with the sewer line. In worst cases, raw sewage can back up inside the drains, which can cause health hazards and property damage. If water backs up consistently, seek help from a professional plumber immediately.

Gurgling sounds from the toilet

When drains flow smoothly, they do not make much noise. Gurgling or bubbling noises from the toilet after flushing or while running an appliance indicates that something is blocking the water from flowing through the pipe. Clogs in the main sewer line can cause the drains to gurgle. Locate and clear the clog to avoid extensive damage. 

Water draining slowly

No sewer line becomes completely clogged suddenly. The water begins to drain slowly before it refuses to drain at all. Slow-moving drains can indicate an issue with the main sewer line. Blockages that run deep in the sewer line can lead to cracks, leaks, and sewage back-up.

Sewage smells

Another telltale sign of a sewer line issue is an unpleasant rotten egg, sewage, or burning sulfur-like smell from the drains or basement. A leak in the main sewer line is usually responsible for sewage smells. Call a plumber as soon as possible to look into the problem, as sewer gasses leaking into the house are dangerous. 

Mold and mildew growth

Cracked or broken sewer lines can cause water and moisture to seep into the home, leading to mold growth. Noticing wet patches or mold and mildew on the ceiling or walls can indicate a likely leak in the sewer line.

Foundation issues

When left unchecked and unrepaired for an extended period, sewer line leaks can cause various foundation damages, like cracks, sinkholes, or the home settling. Immediately get the sewer line repaired if there are noticeable cracks in the home foundation. 

Lush grass patch in the lawn

Another sign of a sewer line problem is when some lawn areas develop unusually lush, green, and vibrant grass than their surroundings. Broken sewer lines cause the sewage water to leak, and its organic materials act as fertilizer for the grass. Other signs of a sewer line leak include standing water, soggy patches, or a sewage smell in the yard. 

Keep the sewer in optimal condition

From flooding, mold, and bacterial growth to contaminated water, sewer line problems can threaten the property’s structural integrity and the family’s health. Call a plumbing company to schedule an inspection if one notices any of the above issues. Professional plumbers are experienced and have the tools and equipment to find the root cause of the problem and fix it quickly to restore proper sewer line functioning.
