Step 1 · Shut Off Main Water and Drain Pipes

The first and most critical step is to completely shut off the water supply to your entire home. Locate the main water shutoff valve, which is typically found in a basement, crawl space, or utility closet near where the main water line enters the house. Turn the valve handle clockwise until it stops. To drain the remaining water from the plumbing system, go to the lowest level of your home (like a basement sink or outdoor spigot) and open the faucet. Then, open the faucet at the sink where you'll be working to relieve any remaining pressure and drain the line. Place a bucket and towels directly under the angle stop you will be replacing to catch any residual water.
