Understanding the Anatomy of a Leaking Sink
Before you can fix a **leaking sink**, it’s essential to understand its components. A typical sink consists of the faucet, drain, supply lines, and P-trap. Each of these parts can be a potential source of leaks, and identifying the culprit is the first step towards a successful repair. Let’s break down each component:
* **Faucet:** The faucet is the most visible part of the sink and is responsible for controlling the flow of water. Leaks can occur around the base of the faucet, from the spout, or from the handles.
* **Drain:** The drain is responsible for carrying wastewater away from the sink. Leaks can occur around the drain flange (where it connects to the sink), from the drainpipe connections, or from corrosion.
* **Supply Lines:** Supply lines carry hot and cold water to the faucet. They are typically made of flexible braided stainless steel or copper. Leaks can occur at the connections to the faucet or shut-off valves, or from damage to the lines themselves.
* **P-Trap:** The P-trap is a U-shaped pipe located under the sink. It traps debris and prevents sewer gases from entering your home. Leaks can occur at the connections to the drainpipe or from corrosion.
Understanding how these components work together is crucial for accurately diagnosing the source of a **leaking sink** and implementing the appropriate repair.
Common Causes of Sink Leaks
Several factors can contribute to a **leaking sink**. Here are some of the most common culprits:
* **Worn-Out Washers and O-Rings:** Over time, the rubber washers and O-rings inside the faucet can become brittle and crack, leading to leaks around the handles or spout.
* **Loose Connections:** Vibrations and temperature changes can cause connections between pipes and fittings to loosen, resulting in leaks.
* **Corrosion:** Corrosion can weaken pipes and fittings, eventually leading to leaks. This is especially common in older homes with galvanized steel pipes.
* **Damaged Supply Lines:** Supply lines can be damaged by kinks, punctures, or age, resulting in leaks.
* **Clogged Drains:** A clogged drain can cause water to back up and leak from the drain flange or overflow drain.
* **High Water Pressure:** Excessively high water pressure can stress plumbing components and contribute to leaks.
Tools and Materials You’ll Need
Before you start working on a **leaking sink**, gather the necessary tools and materials. Here’s a basic list:
* **Adjustable Wrench:** For tightening and loosening nuts and fittings.
* **Basin Wrench:** For reaching hard-to-access nuts on the faucet.
* **Pliers:** For gripping and manipulating small parts.
* **Screwdrivers (Phillips and Flathead):** For removing screws and disassembling faucet components.
* **Plumber’s Tape (Teflon Tape):** For sealing threaded connections.
* **Plumber’s Putty:** For sealing the drain flange.
* **Replacement Washers and O-Rings:** Matching the size and type of the originals.
* **Bucket:** For catching water.

* **Penetrating Oil (e.g., WD-40):** For loosening corroded nuts and bolts.
Having these tools and materials on hand will make the repair process much smoother and more efficient.
Diagnosing the Source of the Leak
Finding the exact source of the **leaking sink** is crucial for a successful repair. Here’s a systematic approach to diagnosis:
1. **Dry the Area:** Use towels or rags to thoroughly dry the area under and around the sink. This will make it easier to spot the source of the leak.
2. **Check the Faucet:**
* Run the water and observe the faucet closely. Look for leaks around the base, spout, and handles.
* If the leak is coming from the handles, try tightening the packing nuts (the nuts located just below the handles). If that doesn’t work, you may need to replace the washers or O-rings inside the faucet.
* If the leak is coming from the spout, the O-rings or cartridges inside the faucet may need to be replaced.
3. **Inspect the Drain:**
* Fill the sink with water and let it drain. Observe the drain flange and drainpipe connections for leaks.
* If the leak is coming from the drain flange, you may need to remove it, clean the area, and apply fresh plumber’s putty before reinstalling it.
* If the leak is coming from the drainpipe connections, try tightening the slip nuts. If that doesn’t work, you may need to replace the washers or the drainpipes themselves.
4. **Examine the Supply Lines:**
* Check the supply lines for any signs of leaks, especially at the connections to the faucet and shut-off valves.
* If you find a leak, try tightening the connections. If that doesn’t work, you may need to replace the supply lines.
5. **Check the P-Trap:**
* Inspect the P-trap for leaks, especially at the connections to the drainpipe.
* If you find a leak, try tightening the slip nuts. If that doesn’t work, you may need to replace the washers or the P-trap itself.
By systematically checking each component, you should be able to pinpoint the source of the **leaking sink** and determine the appropriate repair.
Step-by-Step Repair Guides for Common Sink Leaks
