How Often Should You Get Your Sewer Line Inspected?
A practical inspection schedule for Nashville and Franklin homeowners — how often to scope your line, what triggers an immediate inspection, and what the camera actually reveals underground.
How Often Should You Schedule a Sewer Line Inspection?
Most plumbers and sewer professionals agree on a straightforward schedule, but the right frequency depends on the age of your pipes, how your property is used, and the landscaping around your sewer lateral. Here is the general recommendation:
| Property type | Recommended frequency | Why |
|---|---|---|
| Standard residential (pipes installed after 1983) | Every 2 years | Modern PVC and ABS pipes are durable, but root intrusion, settling, and ground movement still develop over time |
| Older homes (pre-1983 clay, cast iron, or Orangeburg pipes) | Every year | Clay and cast iron joints loosen with age; Orangeburg collapses; annual inspections catch problems early |
| Homes with large trees near the sewer lateral | Every year | Roots seek moisture and nutrients — they will find even hairline cracks in a sewer joint |
| Commercial and multi-unit properties | Every 6 months | Higher volume, grease buildup, and regulatory liability make semi-annual scoping cost-effective |
These intervals are preventive. A sewer camera inspection every two years for a newer home costs far less than an emergency dig when a line fails without warning.
When to Get an Inspection Right Away
Scheduled inspections are important, but certain situations call for an immediate camera scope — regardless of where you are in your regular cycle:
- Before buying a home — a sewer scope inspection is one of the highest-ROI add-ons to a home inspection. It can reveal thousands of dollars in hidden damage that a general inspector will never see.
- Recurring drain clogs — if the same drain backs up more than twice in a year, the cause is usually in the main sewer line, not the branch line. A camera finds the real problem.
- After major landscaping or construction — new trees, retaining walls, pool installations, and driveway pours can shift, crush, or sever a sewer lateral. Inspect within 30 days of any heavy ground work near the line.
- After severe storms or flooding — Middle Tennessee storms push saturated soil against pipes and can shift joints. A post-storm scope confirms nothing moved.
- Slow drains throughout the house — when multiple fixtures drain slowly at the same time, the issue is almost always downstream in the main sewer line.
- Sewage odor in the yard — a persistent sewer smell outdoors means the line is leaking effluent into the soil. That is both a health concern and a sign the pipe needs immediate attention.
- Unexplained lush patches in the lawn — a section of grass that is noticeably greener or grows faster than the rest is often fed by a leaking sewer line directly below it.
What a Sewer Camera Inspection Actually Reveals
A sewer camera inspection sends an HD CCTV camera head through the full length of your sewer lateral. The technician watches the footage in real time and records it so you can see exactly what is happening inside your pipe. Here is what the camera typically uncovers:
| Finding | What it means | Urgency |
|---|---|---|
| Root intrusion | Tree roots have entered through joints or cracks and are growing inside the pipe, catching debris and narrowing flow | Moderate to high — roots worsen every season |
| Cracks and fractures | The pipe wall is cracked but still holding shape; water and roots can enter through the crack | Moderate — monitor or repair before full failure |
| Bellied or sagging pipe | A section of pipe has settled and created a low spot where waste and water pool, causing slow drainage and recurring clogs | High — bellies do not self-correct and trap debris over time |
| Offset joints | Two pipe sections have shifted apart at the joint, creating a ledge that catches solids and allows root entry | High — offset joints are a top cause of main-line clogs |
| Scale and mineral buildup | Calcium, iron, or grease deposits have narrowed the pipe interior, reducing flow capacity | Moderate — hydro jetting can restore flow in most cases |
| Pipe collapse | A section of pipe has fully caved in, blocking flow entirely or nearly so | Emergency — requires trenchless repair or replacement |
Knowing exactly what is wrong — and where — is the difference between a targeted repair and an unnecessary excavation. The camera combined with sewer line locating pinpoints the problem to the foot, so the repair scope matches the actual damage.
Nashville and Franklin Sewer Line Considerations
Middle Tennessee has specific conditions that make regular sewer inspections especially important:
- Aging clay pipe infrastructure — many Nashville and Franklin neighborhoods built before 1980 still run on vitrified clay sewer laterals. Clay joints are rigid and lose their seal over decades, creating entry points for roots and groundwater.
- Tree-heavy neighborhoods — mature hardwoods like oaks, maples, and sweetgums are part of what makes Franklin and the Nashville suburbs beautiful, but their root systems are aggressive. A 50-year-old oak can send roots 100 feet or more toward a sewer line.
- Seasonal soil movement — Middle Tennessee's clay-heavy soil expands when wet and contracts when dry. This seasonal cycle stresses pipe joints year after year, especially in spring and late summer.
- Heavy spring rain events — Nashville averages nearly 50 inches of rain per year, with the heaviest months in spring. Saturated soil increases hydrostatic pressure against aging pipe walls and can accelerate joint separation.
- New construction near older lines — rapid development in Williamson and Davidson counties means heavy equipment working near established sewer laterals. Vibration and grade changes can damage lines that were functioning fine before the project next door started.
If your Franklin or Nashville home was built before 1983 and sits on a wooded or tree-lined lot, an annual sewer camera inspection is the single most cost-effective maintenance step you can take for the line.

Sewer Line Inspection Frequency — FAQ
How often should I get my sewer line inspected?
Every 2 years for most homes with pipes installed after 1983. Homes with older clay or cast iron pipes should be inspected annually. Commercial properties and multi-unit buildings benefit from inspections every 6 months due to higher usage volume.
Do I need a sewer inspection before buying a house in Nashville?
Strongly recommended. A pre-purchase sewer scope is one of the highest-value add-ons to a standard home inspection. It can uncover root intrusion, bellied pipe, offset joints, and other damage that costs thousands to repair — none of which a general home inspector will catch. Prodigy offers a $99 real-estate sewer scope for buyers in the Nashville and Franklin area.
What does a sewer camera inspection cost?
A standalone sewer camera inspection from Prodigy is $150. That fee is waived — making the inspection free — when you book any repair or cleaning service. A pre-purchase real-estate sewer scope is $99.
How long does a sewer camera inspection take?
A typical residential sewer camera inspection takes 30 to 60 minutes, including setup, the scope itself, and reviewing the footage with you on site. Longer or more complex lines may take slightly more time.
Can tree roots really damage my sewer line?
Yes, and in Middle Tennessee it is one of the most common problems we find. Mature hardwoods send roots far beyond their canopy in search of moisture and nutrients. Even a hairline crack at a pipe joint is enough for a root tendril to enter and grow. Once inside, roots expand and catch debris until the line clogs or the pipe cracks further. Annual inspections in tree-heavy areas catch root intrusion early, before it requires a major repair.
What happens if the camera finds a problem?
We review the footage with you on the spot, explain what the camera found, and outline your options — from hydro jetting for buildup and minor root intrusion, to trenchless sewer repair for cracks, offsets, or bellied sections. We never pressure a decision on the spot, and the recorded video is yours to keep regardless.
