The answer to 'shut-off valve maintenance' is that regular maintenance is essential to ensure your home's shut-off valves are functioning properly. Shut-off valves are critical safety devices that allow you to quickly turn off the water supply in case of a plumbing emergency or when performing repairs.
To maintain your shut-off valves, you should check them at least once a year by turning them fully open and then fully closed. This helps keep the valves lubricated and prevents them from becoming stuck or seizing up. You should also check for any leaks around the valve stems or connections. If you notice any issues, it's best to have a professional plumber inspect and repair the valves.
