The answer to 'drain making noise' is that a noisy drain is usually caused by a partial clog or obstruction in the drain pipe. Common symptoms include gurgling, whistling, or rumbling sounds coming from the drain when water is running.
Some common causes of noisy drains include food debris, hair, soap scum, and other buildup in the pipes. This can create turbulence and vibrations as water flows through the restricted area. In some cases, the drain pipe itself may be damaged or improperly installed, leading to noises. It's important to address the underlying issue to stop the noise and prevent further problems.
