Cost: $10,000 in tools
Time: 1-2 hours
Skill Level: Advanced

Tools List:
- Gloves [https://amzn.to/31x4uDf]
- Drain Camera [https://amzn.to/2XdB5Pa]
- Drain Locator Tool [https://amzn.to/2Xb9Btz]

Steps:
1. Use a drain camera to look for possible obstructions in the main drain line of the house. Ensure the distance meter is reset before entering the drain to give an accurate measurement of where in the pipe a clog may be located.
2. Use a line locator to confirm the location of the camera under the floor.

Richard used a SeeSnake camera system to see inside the drain line and a SR-24 Line Locator with Bluetooth and GPS to locate the pipe under the floor. Both are manufactured by Ridgid [https://www.ridgid.com/].

Plumbing contractors can be hired to help diagnose drain problems. This diagnostic equipment can also be rented from home centers or tool rental shops.
