The answer to 'shower making noise' is that there are several common causes, including issues with the shower valve, water pressure, or a problem with the plumbing. Symptoms may include a high-pitched whistling or humming sound, or a loud banging or knocking noise. Solutions can range from tightening components to replacing worn parts, depending on the specific issue.
If the noise is a persistent or recurring problem, it's best to have a professional plumber inspect the shower and diagnose the underlying cause. While some minor repairs may be possible for DIY homeowners, more complex issues should be addressed by an experienced plumber to ensure the problem is resolved safely and effectively.
