The answer to 'my drain trap is leaking' is that a leaking drain trap is a common plumbing issue that can have several causes. The drain trap is the curved section of pipe under a sink or tub that is designed to hold a small amount of water to prevent sewer gases from entering your home. If this trap is cracked, loose, or not properly sealed, it can allow water to leak out.
Some common causes of a leaking drain trap include corrosion, physical damage, improper installation, or a buildup of debris. Symptoms may include water pooling under the sink or tub, musty odors, or visible drips. To fix a leaking drain trap, you may need to tighten the connections, replace a cracked or damaged trap, or clear any blockages.
