Answer 1

Learn how to find a blockage in a drain line due to a pipe collapse using inspection cameras, smoke tests, and hydrostatic pressure tests.

Step-by-step explanation:

How to Find Blockage in a Drain Line due to a Pipe Collapse

When a drain line is blocked due to a pipe collapse, there are several methods to locate the blockage:

1. Inspection Camera: Use a specialized camera that can be inserted into the drain line to visually inspect the interior and identify the location of the collapse.
2. Smoke Test: Introduce smoke or colored dye into the drain line and observe for any signs of leakage or escaping smoke, indicating the location of the collapsed pipe.
3. Hydrostatic Pressure Test: Apply pressure to the drain line to identify areas with increased resistance, which may indicate a pipe collapse.

By using these methods, you can accurately find the blockage caused by a pipe collapse in a drain line.
