Why Does My Faucet Keep Dripping and How to Fix It
Whether it's a kitchen faucet, bathroom faucet, or an outdoor faucet, a dripping faucet can be more than just a nuisance; it can also indicate potential water wastage and higher utility bills. In this article, we will explore the common causes of faucet dripping and provide step-by-step guides on how to fix them, including replacing gaskets, adjusting valve settings, and handling excessive water pressure.
Common Causes of Faucet Dripping
The most common reasons for a dripping faucet include:
Defective Gasket or Seals: Over time, the rubber or plastic gaskets that seal the faucet can become worn or damaged. This allows water to seep through, causing the dripping sound. Worn or Malfunctioning Valve: The valves within the faucet handle can deteriorate if notmaintained, leading to leaks. Excessive Water Pressure: High water pressure can cause the faucet to drip, even if the gaskets and valves are in good condition.Step-by-Step Guide: Fixing a Dripping Faucet
Replacing a Faucet Washer
One of the most common culprits for a dripping faucet is a faulty washer. Here’s how you can replace it:
Disassemble the Faucet: First, shut off the water supply under the sink. Open the faucet to drain any remaining water. Use an adjustable wrench to remove the packing nut and take out the assembly. Identify the Washer: The brass screw and washer should be obvious. Identify the type of washer used (rubber for individual taps). Remove the Old Washer: If the old washer is stuck, try prying it out with a screwdriver. Replace the Washer: Purchase a replacement washer from your local hardware store. Insert the new washer and reassemble the faucet. Test the Faucet: Open the faucet to check if the drip has stopped. Adjust as necessary.Adjusting or Replacing the Valve Stem
If the dripping is coming from the stem, you may need to replace the valve stem or adjust it. Here’s what to do:
Identify the Valve Stem: Locate the valve stem as it extends from the handle. Remove the Stem: Use an adjustable wrench to loosen the packing nut and remove the stem. Check for Wear or Damage: Inspect the stem for signs of wear or damage. If it’s severely worn, replace it. Replace or Re-thread the Stem: If the stem is damaged, replace it with a new one. If it’s just worn, you can use a repair kit from the hardware store to re-thread the stem. Reassemble the Faucet: Once the new or repaired stem is in place, reassemble the faucet and test for leaks.Checking for Excessive Water Pressure
If the dripping persists, the issue might be related to water pressure:
Shut Off the Water Supply: Ensure the water main is completely off before making any adjustments. Install a Pressure Reducing Valve (PRV): A PRV can help regulate water pressure and prevent leaks caused by high pressure. Test the Faucet: After installing the PRV, open the faucet and check if the dripping has stopped.Preventative Measures
To prevent future leaks, regularly inspect your faucet components and replace them as needed. Keep your tools and repair kits handy. Also, ensure that your water pressure is within recommended levels (usually a maximum of 80 PSI).
Conclusion
A dripping faucet can be frustrating, but with the right tools and a bit of effort, you can fix it yourself. Whether it's replacing a washer, adjusting a valve, or installing a pressure reducing valve, these steps can help you maintain a leak-free faucet and save water.
