For anyone who’s considering making an offer on a new house or experiencing drainage or foul smells in their own home, a camera drain and sewer inspection is a surefire way to see—with your own eyes—whether or not there’s a problem in the drainage system.
It can potentially save you thousands of dollars down the road, especially if it helps flag a long-neglected plumbing system before you purchase a house. A drain inspection can also find a problem in its early stages, when it’s simpler and more affordable to repair.
What Is A Drain Inspection?
When a plumber inspects your drain and sewer system, they snake a small, high-definition, waterproof camera that’s attached to a flexible rod through the drainage pipes and into the main sewer line. This gives the plumber a live look at what might be blocking pipes or otherwise causing plumbing issues.
What Kinds Of Drainage Problems Can It Uncover?
Getting a real-time look at your drain and sewage pipes can demystify almost any drainage problem.
- Pipes that are collapsed, cracked, or crushed, especially in older houses. Tree roots are a common culprit.
- Major clogs, including items that were inappropriately flushed, grease buildup, or accumulated debris.
- Misaligned or sagging pipes.
- Failing pipe joints.
How Can A Drain Inspection Help?
If your sewer backs up, it can expose you and other members of your household to bacteria, mold, and foul odors that can expose you to health risks.
A backed-up sewer can also make daily living difficult or impossible, disrupting bathing, cooking, or using the toilet until the issue is resolved.
When Do You Know If You Need A Drain Inspection?
If you’re considering making an offer on a house, a drain inspection can give you information about the property and help you decide whether to make an offer, or plan for future maintenance.
If you’re experiencing slow-draining toilets, sinks, showers, and/or tubs, or detecting a stench, a drain inspection is a good idea.
