What You Need To Know About Having A Sewer Camera Inspection
Your sewer line often sits inside the slab or foundation of your home, making it difficult to examine. It’s unrealistic to tear up thick concrete or dirt in your yard only to find out that the clog didn’t develop where you thought.
A sewer line inspection uses a camera at the end of a long cord to examine the inside of your sewer pipes, which is especially important in these difficult-to-access spaces.
You may think that your sewer relates only to your toilet as many people think toilets and sewers go hand in hand. The toilet leads to the sewer line, along with all the other sink and shower drains in your home.
You will not need a sewer line inspection to help you simply unclog a toilet. The inspection is designed to reach deeper clogs in the main sewer line itself.
Most inspections not only provide a photo display of your pipe lining but also a detailed video inspection that can be recorded.
When Do You Need To Have A Sewer Line Inspection?
Sewer line inspections serve the purpose of mapping out and finding a clog deep within your plumbing system.
Before you purchase a home, you need to get a home inspection which may include a sewer scope inspection. Sometimes this is an add on to your report, so be sure to ask about it. The home inspector will produce their findings in writing, detailing any foreseeable repair costs that may arise
You may also be required to get a sewer inspection if you start certain construction or remodeling work such as pool installation, depending on the building codes in your area.
Sometimes, the inspection happens out of necessity due to a clog.
Signs That You May Have a Sewer Line Clog
- Multiple slow drains
- Sewage backup
- Foul odor
- Gurgling noises
In some cases, you may be able to address the clog yourself using a drain snake or chemical drain cleaner. However, if those methods don’t work, you’ll require an inspection to locate the source of the blockage.
It’s important to note that sewer line inspections, unfortunately, cannot identify leaks. It’s almost impossible to see a leak from inside a sewer pipe, especially since interior pipes accumulate gunk, such as grease or roots.
However, that doesn’t mean that you shouldn’t take action if you suspect a leak in your sewer line.
Indications of a sewer leak in your sewer line:
- Excessive moisture in yard
- Foundation cracks
- Excessively high water bills
Who To Call For A Sewer Line Inspection?
A professional plumber should be able to perform a sewer line inspection for you. However, it’s important for you to verify that your plumber provides this service regularly as it requires specialized equipment and knowledge.
You can also save money by performing the inspection yourself if you buy the right equipment.
How Much Does A Sewer Line Inspection Cost?
On average, a sewer line inspection will cost an average of $685. However, the service comes with a wide price range between $250 – $1175.
One of the main factors that determine the costs involves the quality of the data as well as the type of data you receive. An advanced sewer video inspection will cost more than a couple of low-resolution pictures.
In some cases, the responsibility for the cost of the sewer line repair may fall on the local government. Since this varies from location to location, you should learn the ordinances in your area in advance so you don’t run into any surprises.
When done as a part of preventative plumbing maintenance, your homeowner’s insurance policy may cover the cost. Talk to your insurance agent to get the details of your specific plan.
8 Steps Of A Sewer Line Inspection
Step 1: Connect Correct Attachment to Sewer Line Tool
First and foremost, you need the right tools for the job.
The tool required for a sewer line inspection is a long, flexible cable, known as an endoscope, that can navigate through your pipes, similar to an auger. However, this tool has a camera attachment at the end.
Step 2: Verify Camera Connected to Monitor
The camera on the flexible cable connects to a monitor so that the plumber can look at what the camera shows. It’s best to verify that the camera is connected to the monitor before starting work.
In most cases, the camera will connect to the monitor using WiFi or a USB cord, and the plumber can watch the images on a tablet, smartphone, or dedicated monitor.
Step 3: Feed Sewer Line Tool Into Cleanout
The plumber will feed the tool into the cleanout in your yard. The cleanout is an opening to your sewer line specifically to grant access for plumbers and homeowners to perform maintenance.
You will need a wrench to open the cleanout. You should also remember that most cleanouts are outside and may not have access to an electrical outlet.
Step 4: Analyze Images On Monitor
As the tool makes its way through the sewer line, the plumber will look for a sewer problem. As we mentioned, you probably won’t see a leak. However, the camera will make it very obvious to find a clog.
Step 5: Mark Problem Area and Locate Lines
The plumber will mark the location of a sewer clog based on the information they received from the inspection.
They will also mark the location of different plumbing lines on your property, especially if you don’t have it clearly indicated already.
Having the lines clearly marked will prevent problems down the line if you plan to do yard work or build on the land.
Step 6: Remove and Clean Sewer Line Tool
After the inspection, the plumber will remove the tool and clean it thoroughly. Since the camera contains electronics, they probably won’t dowse the entire thing in water but rinse it off gently before drying it completely.
Step 7: Remove Clog From Sewer Line
The plumber will now repair the clog at its source. If the clog developed underneath your foundation, the plumber may attempt to use a drain snake or chemical drain cleaner to break it up.
If the clog developed in an easy to locate area, they may dig in your yard to gain access to the pipe then disassemble it to clean the clog directly. Finally, they will reassemble the plumbing or replace damaged pieces with new pieces.
Step 8: Prevention
Learn how to prevent a grease clog in your sewer line, including your septic tank and sump pump.
Start by not pouring grease and fat down the drain. Instead, dispose of those materials in the garbage.
Other items not to put down your drain include:
- Coffee grounds
- Fibrous vegetables
You can also create your own homemade grease trap. It’s easier than you might expect!
Final Thoughts On Having A Sewer Line Inspection
A sewer backup can lead to a serious plumbing issue that requires expensive sewer line repair due to a slow drain or damaged pipe. A sewer line video inspection can spot blockage or another sewer line problem so that you can tackle the problem directly with DIY sewer repair.
Get an inspection before your sewer line creates a drain on you and your household.
