The answer to 'shut-off valve making noise' is that a noisy shut-off valve is often caused by mineral buildup, corrosion, or wear and tear on the valve components. Symptoms may include a whistling, grinding, or knocking sound when the valve is opened or closed.
In many cases, the issue can be resolved by shutting off the water supply, disassembling the valve, and cleaning or replacing the internal parts. However, if the valve is severely damaged or the noise persists after repair, it's best to replace the entire shut-off valve. This is a task that is generally recommended for a professional plumber, as improper installation or repair can lead to leaks or further damage.
