The first place to check for a leak is the sink trap, also known as the P-trap. This curved pipe underneath the sink is designed to trap a small amount of water, creating a seal that prevents sewer gas from entering your home. Over time, this seal can become compromised due to debris buildup or loose connections, causing water to leak out. To fix a leaky sink trap, simply tighten the connections or clean out any debris.How to Fix a Leaky Sink Trap | Home Guides | SF Gate
