The answer to 'drain trap slow draining' is that a slow-draining drain trap is often caused by a blockage or buildup in the trap or the connected pipes. Common symptoms include water draining slowly, gurgling sounds, or foul odors coming from the drain.
Some common causes include hair, soap scum, food particles, or other debris accumulating in the trap or pipes. Over time, these can restrict water flow and lead to a slow drain. In some cases, the trap may need to be cleaned or the connected pipes may need to be snaked to clear the blockage.
