The answer to 'P-trap making noise' is that a noisy p-trap is usually caused by a buildup of debris or a loose connection. This can lead to water draining slowly or gurgling sounds coming from the drain. The most common solutions are to clean out the p-trap or tighten the connections.
If the noise is persistent or you notice other issues like water leaks, it's best to call a professional plumber to diagnose and fix the problem. Attempting to disassemble or repair the p-trap yourself can be risky if you don't have the right tools and experience.
