Drain camera inspections are part of a building inspection that involve the use of a special camera to investigate the condition of your plumbing and drainage systems. The camera is driven into the pipes from an access point, and it records footage and images of the insides of the pipe. These images are analyzed by experts to find possible blockages, flaws and leaks. The camera is called a drain camera.
The plumbing network is one of the most essential systems of any building. The drainage system is equally as important. The pipes and other components of these systems are often hidden behind the walls or under the ground. It is most likely that when they develop problems, you will not be able to detect them immediately. A leak in your plumbing system will cause water wastage, while one in your drainage system might spill dirty and contaminated water, which is clearly a health hazard.
The best way to detect problems with plumbing or drainage systems is the use of a drain camera. It will save you money, time, potential unwanted damage and hassle. It is important that you get your plumbing systems and drainage systems inspected regularly, to ensure any developing problems are caught in time.
How is A Drain Camera Inspection Done?
As mentioned above, a drain camera inspection is very simple and straightforward. A small camera attached at the front of a long cable is put into and pushed along the pipes. The camera records footage of the condition of the inside of the pipe. A drain camera inspection is often done by a qualified technician.
When the technicians arrive at your home they will first take time to locate where the plumbing lines and the access points are. It is from the access points that they will be able to insert the cameras into the pipes. If you have a map of your plumbing system, it would be a great help to them as they try to locate the access points. If you do not where the access point is, you may want to first bring in a thermographic inspection specialist to quickly and easily locate it.
How Does a Drain Camera Work?
The camera captures and transmits real footage from inside the pipes. The footage can be seen on a screen that’s connected to the camera through a long cable. Whether it’s your home or you are in the market to purchase you should be present during the inspection so that you can watch the footage as well. During the inspection, the technician will explain the condition of the pipes based on the footage.
At times, it might not be possible to drive the camera through the entire pipe lateral due to a blockage or damage. In such instances, the drain camera inspection is often rescheduled for another time, when the damages and blockages have been rectified. Ultimately, these blockages and damages are what the inspector would be looking for in the first place. Such a point will be marked on the ground so that it is easier for the repairman to locate the blocked or damaged spot.
What to Expect During a Drain Camera Inspection?
A drain camera inspection is often a quick process for experienced inspectors. It involves locating the access point, driving the camera through the drainage or plumbing system, and recording the footage. You might have to assist the inspectors with locating where the access points are. As mentioned above, if you stay close enough, the inspector will explain various things and give you a perspective of the condition of your drainage or plumbing system. Also, you are at liberty to ask any questions that you might have about the inspection
You don’t have to worry about the inspectors demolishing your walls or digging up your backyard to access the pipes. If you have a map outlining the layout of drainage of plumbing pipes in your home, it would certainly be of great help to the inspectors while they’re trying to locate the access point. Both you and inspector will be watching the footage of the insides of the pipes from a monitor on the ground.
Can A Drain Camera Detect Leaks?
A drain camera inspection is meant to detect all problems that your drainage and plumbing system might have. It can detect if your drainage of plumbing pipes have leaks. However, it normally detects leaks that are as a result of large cracks or holes. The best way to investigate leaks in your home is through a thermographic infrared inspection. A thermographic infrared inspection detects wet spots, that are often caused by leaks, by imaging thermal emission differences due to the difference in moisture content.
A drain camera inspection majorly detects issues like corrosion and blockages. However, drainage and plumbing system inspector must also inspect the pipes from the outside. This ensures that even the tiniest of leaks are caught. Often times, a drain camera inspection is done as a part of a whole building inspection. As such, any leaks that might be there will be caught during other types of inspection, such as a moisture inspection.
Many inspection agencies will have their technicians carry-back the footage taken to their officers so that they can analyze it further. They will then send the requesting party a comprehensive report of what the inspection revealed and the footage itself. They might also offer recommendations on what to be done to restore the plumbing or drainage system to perfect condition. Ensure that you work with a certified home inspection agency. You can check with your local government for a list of the certified home inspection agencies in your area.
