The answer to 'why is my P-trap clogged' is that a clogged P-trap is a common plumbing issue often caused by hair, soap scum, food particles, or other debris buildup. The P-trap is the curved pipe under your sink that is designed to hold water and prevent sewer gases from entering your home. When this trap becomes blocked, it can cause water to back up and drain slowly.
Some common symptoms of a clogged P-trap include slow draining water, gurgling sounds, or even water pooling under the sink. To fix a clogged P-trap, you can try using a plunger or a plumber's snake to clear the blockage. If the clog is severe or you are uncomfortable doing it yourself, it's best to call a professional plumber to assess and resolve the issue.
