The answer to 'P-trap slow draining' is that a slow-draining P-trap is usually caused by a clog or blockage in the trap itself or the drain line. Common symptoms include water draining slowly, gurgling sounds, or foul odors coming from the drain. Solutions can range from DIY methods like using a plunger or drain snake to calling a professional plumber if the clog is more severe or difficult to reach.
The P-trap is the curved section of pipe under a sink or bathtub that is designed to hold a small amount of water to prevent sewer gases from entering the home. Over time, this trap can become clogged with hair, soap scum, food particles, and other debris, causing the water to drain slowly. Attempting to clear the clog yourself with a plunger or drain snake is often the first step, but if that doesn't work, you may need to disassemble the trap or call in a professional plumber to fully clear the blockage.
