The answer to 'drain cleaning making noise' is that a noisy drain is usually caused by a blockage or buildup in the drain pipe. This can create air pockets and turbulence that result in loud gurgling, bubbling, or whistling sounds. Common causes include hair, soap scum, food debris, or other foreign objects accumulating in the drain.
If the drain noise is persistent or getting worse, it's a sign that the blockage is worsening and should be addressed. In many cases, you may be able to clear the drain yourself using a plunger, drain snake, or chemical drain cleaner. However, if the noise persists or the drain isn't clearing, it's best to call in a professional plumber to diagnose and fix the underlying issue.
