The answer to 'drain making noise' is that a noisy drain is often caused by a buildup of debris, a problem with the plumbing system, or air bubbles in the pipes. Common symptoms include gurgling, whistling, or humming sounds coming from the drain. Solutions can range from simple DIY fixes to more complex professional plumbing repairs.
If the noise is a gurgling or bubbling sound, it may be caused by a partial clog or air getting trapped in the pipes. You can try using a plunger or drain snake to clear the blockage. If that doesn't work, the issue may be with the vent system or a problem deeper in the plumbing that requires a professional inspection.
