The Unsung Hero: Your Sink Trap

Ever wondered about that U-shaped or P-shaped pipe directly under your sink? That's your "sink plumbing trap," and it's a small but mighty hero in your home's plumbing system.

Its primary functions are twofold:

1. Prevents Sewer Gas: The trap always holds a small amount of water. This water acts as a seal, blocking unpleasant and potentially harmful sewer gases from entering your home through the drain.
2. Catches Debris: It's also designed to catch objects like rings, earrings, or small toys that accidentally fall down the drain, preventing them from going further into your plumbing system where they could cause major clogs.

While it's excellent at its job, the trap can also be where clogs most frequently occur. If you have a slow drain in your sink, checking the trap is often the first step a plumber will take to diagnose the issue. Understanding your sink trap helps you appreciate this vital, often overlooked, part of your plumbing.
