Test Balls for Drainage Lines To start the process, make sure your main line sewer cleanout is clear of debris and liquid. Next, insert the test ball and inflate it so that it blocks the main line. Fill the sewer system with water and observe the water level for 15-20 minutes.
Hydrostatic Tests are highly recommended when you suspect or know of problems with the sewer lines. Hydrostatic Tests determine if there is a leak under a house or building in the sewer line system. If the system leaks, an Isolation test is performed to 'isolate' where the leaks are located.
Your sanitation district will be able to tell you the approximate depth by going off the plats of how that sewer system was laid out, along with all the laterals, manholes, turns of direction. Everything in Plumbing can be repaired or replaced.
Residential sewer line pipe depths range from as shallow as 18 to 30 inches in depth or 5 to 6 feet deep. However, in colder climates where freezes occur, you often see sewer line depths ranging from 4 to 8 feet deep. This ensures the pipes are below the freeze line.
Your home's sewer cleanout is a crucial part of your plumbing system. You'll usually find it outside, about 1 to 3 feet from where your house meets the ground. Look for a pipe sticking up with a cap on top that might have a square knob or notch for turning.

1 Sewer mains shall be tested for obstructions using a ball test. The sewer main shall be deemed unobstructed if a wood or metal ball having a diameter of 50 mm less than the inside diameter of the pipe can be readily pulled through the sewer main.
Using Cameras to Inspect
By using small cameras connected to a sewer line, sewer inspection companies can quickly and effectively identify issues without the need for digging up large chunks of land. This not only helps to reduce time and effort, but also decreases production costs for sewer repair services.

Homeowners insurance may cover sewer line damage if it stems from something already included in your policy, like a fire or windstorm. Sewer line damage that is the result of wear and tear is excluded from home insurance coverage.
Sewer repair times vary, but patching a minor crack or clearing a clog may only take a few hours. Trenchless sewer line replacement can take around two business days, while traditional replacement can take three or more.
As we mentioned above, it's certainly possible for a homeowner to perform sewer line replacement or sewer line repair. However, it's definitely not an easy job. When you replace the sewer line yourself you run the risk of causing even more damage.

For instance, residential sewer line depth ranges from 18 to 30 inches. However, city sewer line depths are different. Your city's sewer lines must always be deeper than the deepest residential pipe to allow waste to flow downhill. As such, these lines can go as deep as needed.
The most optimal way to inspect the inside of your sewer line (other than digging it up and cracking it open) is to contact your local plumbing company for a sewer line video camera inspection.
You may spot a 3 to 4-inch diameter pipe peeking out of the slab floor of the basement. The sewer drain pipe could be made of plastic or cast iron; it might be copper or brass in rare cases. The stub-out will have a screw-in plug coupled with a square-head lug on it, representing your access to the main drain.
