The answer to 'drain cleaning making noise' is that a noisy drain during or after cleaning is often caused by a blockage that has been dislodged but not fully removed. This can create turbulence and gurgling sounds as water tries to flow through the partially blocked pipe. Common causes include hair, soap scum, food particles, or other debris that has built up over time.
If the noise persists after plunging or using a drain snake, it may indicate a more serious clog deeper in the pipes that will require more thorough cleaning by a professional plumber. Attempting to force the clog through with chemicals or tools can sometimes make the problem worse, so it's best to call in an expert if the noise doesn't subside quickly.
