## 🧪 What Causes Sewer Smells in the First Place?

Before you can fix the problem, you need to understand the possible sources. According to plumbers, here are the **most common causes** of sewer odors in household plumbing:

### 1. **Dry P-Trap**

The P-trap is the U-shaped pipe under your sink or shower. It’s designed to hold water and block sewer gases from coming up. If it dries out (often in rarely used drains), the gases come right through.

### 2. **Blocked or Dirty Vent Pipes**

Plumbing vents release sewer gases through your roof. If they’re blocked (by debris, leaves, or nests), pressure builds up and forces the smell back into your home.

### 3. **Buildup of Gunk and Bacteria**

Hair, soap scum, grease, and food particles can collect in pipes, feeding bacteria that produce **foul-smelling gases**.

### 4. **Leaky Seals or Cracked Pipes**

A damaged drain pipe or seal under the sink can allow sewer gases to escape before they reach the vent system.
