## Understanding Why Your Kitchen Faucet Won’t Shut Off
A kitchen faucet refusing to shut off is rarely a mystery. The most common culprits involve worn or damaged internal components. To effectively diagnose and resolve the issue, it’s crucial to understand the different types of faucets and their potential failure points.
### Faucet Types and Their Common Problems
* **Compression Faucets:** These older faucets use separate hot and cold handles that, when tightened, compress a rubber washer against a valve seat to stop the flow of water. The most common cause of leaks in compression faucets is a worn or cracked washer. Over time, the constant pressure and exposure to water can degrade the rubber, leading to drips and leaks.
* **Ball Faucets:** Identified by their single handle that controls both temperature and flow, ball faucets are more complex than compression faucets. They rely on a slotted ball and rubber seals to regulate water flow. Leaks in ball faucets are often caused by worn-out springs, seats, or the ball itself. Mineral buildup can also interfere with the ball’s movement, preventing a tight seal.
* **Cartridge Faucets:** These faucets also use a single handle, but instead of a ball, they use a cartridge to control water flow. Cartridges can be made of plastic or metal and contain internal seals that can wear out over time. Leaks in cartridge faucets are usually due to a damaged or corroded cartridge. Replacing the cartridge is often the simplest solution.
* **Ceramic Disc Faucets:** These modern faucets use two ceramic discs that slide against each other to control water flow. They are known for their durability and leak-resistant design. However, even ceramic disc faucets can develop leaks if the discs become scratched or damaged by debris in the water supply. These are generally the most reliable, but repairs can be more involved.
### Common Causes of a Dripping Faucet
No matter the faucet type, several factors can contribute to a faucet that won’t shut off:
* **Worn Washers or O-Rings:** These rubber components are essential for creating a watertight seal. Over time, they can become brittle, cracked, or worn, leading to leaks.
* **Corroded Valve Seat:** The valve seat is the area where the washer presses to stop the water flow. Corrosion or mineral buildup on the valve seat can prevent the washer from sealing properly.
* **Loose or Damaged Cartridge:** In cartridge faucets, a loose or damaged cartridge can cause leaks and prevent the faucet from shutting off completely.
* **High Water Pressure:** Excessive water pressure can put extra strain on faucet components, accelerating wear and tear and increasing the likelihood of leaks.
* **Mineral Buildup:** Hard water contains minerals that can accumulate inside the faucet, interfering with the movement of internal parts and preventing a tight seal. This is especially common in areas with hard water.
### Diagnosing the Problem: A Step-by-Step Approach
Before you start disassembling your faucet, take the time to diagnose the problem carefully. This will help you identify the faulty component and choose the right repair solution:
1. **Identify the Faucet Type:** Determine which type of faucet you have (compression, ball, cartridge, or ceramic disc). This will help you understand its internal workings and potential failure points.
2. **Observe the Leak:** Pay attention to where the water is leaking from. Is it dripping from the spout, the handle, or the base of the faucet? This can provide clues about the source of the problem.
3. **Check Water Pressure:** If you suspect high water pressure, you can use a water pressure gauge to measure it. A reading above 80 PSI is considered high and may require a pressure regulator.
4. **Inspect Visible Components:** Carefully examine the faucet handles, spout, and base for any signs of damage, corrosion, or mineral buildup.
