What is the first step to take when fixing a pipe in the wall?

Locate studs and open drywall
Prepare area to contain dust and debris
Turn off water supply to pipe
Contact utility company

The correct answer is: Turn off water supply to pipe

Turning off the water supply to the pipe is the first and most crucial step when fixing a pipe in the wall. This action is necessary to prevent water from leaking out during the repair process, which could cause significant damage to the surrounding area, create a hazardous working environment, and complicate the repair. Without shutting off the water supply, any attempt to open the wall or work on the pipe could lead to uncontrolled water flow, increasing the risk of flooding and making the situation far more difficult to manage. Once the water is turned off, it’s safe to proceed with the necessary steps to locate the problem area, such as opening drywall and preparing the worksite for repairs. The proper order of these tasks helps ensure both safety and efficiency in handling plumbing issues.
