Sewer Inspection Guide: Why Every Homeowner Should Know the Condition of Their Sewer Line

Most homeowners don't think about their sewer line until there's a problem. Unfortunately, by the time warning signs appear, repairs can be costly and disruptive. A professional sewer inspection provides valuable insight into the condition of your underground plumbing and helps identify issues before they become emergencies.  Contact us now at: 360-761-9515

At Mast Plumbing & Mechanical, we use advanced camera inspection technology to evaluate sewer lines accurately and efficiently. Here's what homeowners need to know about sewer inspections and why they're an important part of maintaining your property's plumbing system.

What Is a Sewer Inspection?

A sewer inspection involves inserting a specialized waterproof camera into your drain or sewer line. The camera travels through the pipe, transmitting real-time video that allows plumbers to assess the condition of the system.

A sewer camera inspection can identify:

• Tree root intrusion
• Pipe cracks or breaks
• Corrosion and deterioration
• Pipe sagging (bellies)
• Blockages and buildup
• Misaligned or separated joints
• Foreign objects lodged in the line

This technology eliminates guesswork and helps determine the most effective repair solution.

Signs You May Need a Sewer Inspection

Many sewer line issues develop gradually. If you're experiencing any of the following symptoms, it may be time to schedule an inspection:

Frequent Drain Backups

Occasional clogs happen, but recurring backups throughout multiple drains can indicate a problem deeper within the sewer line.

Slow Drains Throughout the Home

If several fixtures are draining slowly at the same time, the issue may be affecting the main sewer line rather than an individual drain.

Sewage Odors

Persistent sewer smells inside or outside your home can indicate a damaged sewer pipe or blockage.

Lush or Wet Areas in the Yard

Unexpectedly green patches, standing water, or soggy areas may signal a leaking sewer line underground.

Gurgling Sounds

Strange noises coming from toilets or drains can indicate airflow issues caused by sewer line restrictions.

Why Sewer Inspections Are Important When Buying a Home

One of the most overlooked steps during the home-buying process is a sewer inspection.

A general home inspection typically does not include an evaluation of the underground sewer line. A property may appear to be in excellent condition while hidden sewer issues remain undetected.

A pre-purchase sewer inspection can uncover:

• Root intrusion
• Aging or deteriorated piping
• Hidden damage
• Improper repairs
• Potential future expenses

Many homebuyers discover expensive sewer problems shortly after moving in. A sewer inspection helps avoid unpleasant surprises and provides peace of mind before closing.

Common Sewer Problems Found During Inspections

Tree Root Intrusion

Tree roots naturally seek moisture and can enter small pipe openings. Over time, roots grow inside the sewer line, causing blockages and damage.

Aging Pipes

Older homes may contain clay, cast iron, Orangeburg, or other aging pipe materials that become more susceptible to failure over time.

Pipe Bellies

A belly forms when a section of pipe settles and creates a low spot where waste and water collect. This can lead to recurring backups.

Cracked or Broken Pipes

Ground movement, age, corrosion, and construction activity can cause pipes to crack or collapse.

What Happens After the Inspection?

Once the inspection is complete, your plumber will review the footage and explain any findings.

Depending on the condition of the sewer line, recommendations may include:

• Routine maintenance
• Hydro jetting
• Root removal
• Spot repairs
• Pipe lining
• Sewer line replacement

Not every issue requires immediate replacement. Early detection often allows for more affordable repair options.

Benefits of Routine Sewer Inspections

Scheduling a sewer inspection before problems occur offers several advantages:

• Detects hidden issues early
• Helps prevent emergency repairs
• Extends the life of your plumbing system
• Provides valuable information before buying a home
• Saves money on future repairs
• Improves overall plumbing reliability

For older homes, routine inspections can be especially valuable in monitoring pipe condition over time.
