Shut Off Main Water Supply & Drain Lines

What happens here

Locate the main water shut-off valve for the house, typically a 3/4-inch ball valve, and turn it to the closed position (handle perpendicular to the pipe). To relieve pressure and drain residual water from the lines, open a nearby faucet, such as a sink faucet, until water stops flowing. This step is crucial to prevent water damage during pipe disconnection.

Goal: Locate and shut off the main water supply to the house, then open nearby faucets to drain the remaining water from the plumbing lines, ensuring safety during the repair.
