Why Your Kitchen Sink Faucet is Being Stubborn
The incessant drip-drip-drip of a kitchen sink faucet that simply refuses to shut off is a common household annoyance. More than just a minor irritation, a constantly running faucet can lead to a significant waste of water, an unwelcome spike in your water bill, and even potential damage to your sink and surrounding cabinetry. Fortunately, many causes of a kitchen sink faucet stubbornly refusing to turn off are relatively straightforward to diagnose and address. This article will delve into the most frequent culprits behind this plumbing problem, providing you with DIY solutions and guidance on when it’s best to call in a professional. You might just save yourself a hefty plumber’s bill by troubleshooting the issue yourself.
There are several reasons why your kitchen sink faucet might be acting up and refusing to cease its watery flow. Identifying the correct cause is the first step towards a successful repair. Let’s explore the most common culprits:
Worn or Damaged Washers
Washers are small, flat, rubber or fiber rings that create a tight seal within the faucet. They are responsible for preventing water from leaking when the faucet is turned off. Over time, these washers can become worn, cracked, flattened, or even crumble due to constant use and exposure to water. This wear and tear compromises their ability to form a watertight seal, resulting in a persistent drip or a faucet that won’t fully turn off. They may become brittle, or have small pieces that break off leaving gaps.
Corroded or Damaged Valve Seat
The valve seat is the stationary part of the faucet body that the washer presses against to create the seal. Over time, minerals in the water can build up on the valve seat, leading to corrosion and an uneven surface. This corrosion can prevent the washer from seating properly, allowing water to seep through. Nicks or gouges can also appear on the valve seat, resulting in more problems to solve. The result is a faucet that continues to leak, even when tightly shut.
Loose or Damaged O-Rings
O-rings are small, circular rubber gaskets that provide a watertight seal around various faucet parts, such as the spout and the faucet stem. These rings can dry out, crack, or become brittle with age, compromising their ability to maintain a tight seal. When an O-ring fails, water can leak around the affected part, contributing to the problem of a faucet that won’t turn off completely.
Cartridge Troubles for Cartridge Faucets
Cartridge faucets, recognizable by their single handle that controls both temperature and water flow, rely on a cartridge mechanism to regulate water flow. This cartridge contains internal seals and passageways that can become worn, damaged, or clogged with debris. A faulty cartridge can prevent the faucet from shutting off properly, leading to a continuous stream of water.
The Loose Packing Nut Situation
The packing nut is a component found at the base of the faucet handle. Its role is to maintain a tight seal around the stem, preventing water from escaping around the handle itself. When the packing nut becomes loose, water can leak from around the handle, and in some cases, it can also affect the faucet’s ability to shut off completely. It is vital that it is not damaged.
High Water Pressure and How it Contributes
While high water pressure isn’t directly causing the problem, it can exacerbate existing weaknesses in your faucet. If your washers are already worn or your valve seat is slightly corroded, high water pressure can force water through these imperfections more easily, making the leak more pronounced and hindering the faucet’s ability to shut off completely. It’s important to check pressure if the faucet is dripping.
Taking Matters Into Your Own Hands: Troubleshooting and DIY Solutions
Before calling a plumber, consider these DIY solutions. You might be surprised at how easily you can fix the problem.
Safety First and Tools
Before you begin any plumbing repairs, safety should be your top priority. First, turn off the water supply to the faucet. Usually, there are shut-off valves located under the sink. Turning these valves clockwise will stop the water flow.
Next, gather the necessary tools. You’ll likely need a screwdriver (both flathead and Phillips head), an adjustable wrench, pliers, and possibly a faucet wrench or basin wrench. It’s also a good idea to have some penetrating oil on hand to loosen any stubborn parts. And, of course, purchase the necessary replacement parts. Knowing the faucet brand can help you in purchasing the correct parts.
Washer Faucet Repairs: A Step-by-Step Guide
- Disassemble the faucet: Carefully remove the handle (usually secured by a screw). Then, unscrew the faucet stem. Take note of the order in which parts are removed, as this will help you reassemble the faucet later.
- Identify and replace the washer: Examine the old washer. It will likely be worn, flattened, or cracked. Remove it and replace it with a new washer of the same size and type.
- Clean the valve seat: Use a valve seat wrench or a specialized cleaning tool to smooth out any corrosion or mineral deposits on the valve seat. You can also use fine-grit sandpaper to gently smooth the surface.
- Reassemble the faucet: Carefully reassemble the faucet in the reverse order of disassembly, ensuring that all parts are properly aligned and tightened.
Cartridge Faucet Fixes: A Replacement Guide
- Remove the handle: Remove the handle, typically secured by a small screw.
- Remove the retaining clip or nut: You’ll usually find a retaining clip or nut holding the cartridge in place. Remove this clip or nut.
- Remove the cartridge: Carefully pull the cartridge straight up and out of the faucet body.
- Install the new cartridge: Insert the new cartridge into the faucet body, ensuring it’s properly aligned.
- Replace the retaining clip or nut: Secure the cartridge with the retaining clip or nut.
- Reassemble the faucet: Reattach the handle.
Tightening the Packing Nut: A Simple Solution
- Locate the packing nut: This is the nut located at the base of the faucet handle.
- Tighten the nut: Using an adjustable wrench, gently tighten the packing nut. Be careful not to overtighten, as this can damage the faucet.
Tackling High Water Pressure Issues
- Test the water pressure: You can purchase a water pressure gauge at most hardware stores. Attach the gauge to an outdoor faucet and turn on the water. The gauge will display the water pressure in pounds per square inch (psi). Ideally, your water pressure should be between 40 and 60 psi.
- Install a pressure regulator: If your water pressure is consistently above 60 psi, consider installing a pressure regulator on your main water line. A pressure regulator will automatically reduce the water pressure to a safe and consistent level.
When to Seek Professional Help
While many faucet repairs can be tackled by DIYers, there are certain situations where it’s best to call a plumber.
- Severe corrosion or damage: If you find extensive corrosion or damage to the faucet body, pipes, or other plumbing components, it’s best to consult a plumber.
- Broken pipes or fittings: If you accidentally break a pipe or fitting while attempting a repair, call a plumber immediately.
- Inability to identify the problem: If you’ve tried the troubleshooting steps outlined above and you’re still unable to determine the cause of the leak, it’s time to call a professional.
- Complex plumbing issues: If you’re dealing with complex plumbing issues, such as backflow problems or issues with your water heater, it’s best to leave it to the experts.
Preventative Maintenance: Keeping Your Faucet Healthy
Taking a few simple steps to maintain your kitchen sink faucet can help prevent future problems and extend its lifespan.
- Regular cleaning: Clean your faucet regularly with a mild soap and water solution to remove mineral buildup and prevent corrosion.
- Avoid excessive force: Avoid using excessive force when turning the faucet handles. This can damage the washers, cartridges, and other internal components.
- Address leaks promptly: Don’t ignore even the smallest leaks. Addressing them promptly can prevent them from becoming larger, more costly problems.
- Periodic inspections: Inspect your faucet periodically for signs of wear, corrosion, or leaks. Catching problems early can save you time and money in the long run.
