Shut Off Water Supply: Locate shutoff valves, turn off water, and open faucet to drain

Before you begin replacing the rubber gasket on your shower faucet, it's crucial to shut off the water supply to prevent any unwanted spills or leaks. Start by locating the shutoff valves for your shower. In most homes, these valves are situated near the shower, often in a basement, crawl space, or utility closet. If you have individual shutoff valves for hot and cold water, turn both of them clockwise until they are fully closed. If you cannot find dedicated shutoff valves for the shower, you may need to turn off the main water supply to your home, typically located near the water meter.

Once you’ve located and turned off the shutoff valves, head back to the shower to ensure the water supply is indeed off. Turn on the shower faucet to both the hot and cold positions, allowing any remaining water in the pipes to drain out. This step is essential to avoid water pressure buildup, which could cause leaks or difficulty when disassembling the faucet. You should notice that no water comes out after a few seconds, confirming that the water supply has been successfully shut off.

If water continues to flow after turning off the valves, double-check that the correct valves have been closed. Sometimes, shutoff valves can be stiff or difficult to turn, especially if they haven’t been used in a while. You may need a pair of pliers or a valve wrench to fully close them. Ensure the valves are turned as far as they can go to prevent any residual water pressure.

After confirming the water is off, leave the faucet in the open position. This allows air into the system, making it easier to work on the faucet without water suddenly spraying out when you remove the gasket. If your shower has a diverter valve or additional components, ensure all parts are in the open position to fully drain the system.

Finally, take a moment to dry the faucet and surrounding area with a towel or rag. This step not only keeps your workspace clean but also helps you identify any existing leaks or issues that might need attention. With the water supply securely shut off and the faucet drained, you’re now ready to proceed with removing and replacing the rubber gasket.
