Why Is My Faucet Still Running When Turned Off?

The reason why your faucet is still running when turned off can be attributed to several factors.

By examining the different components and potential causes, such as worn-out washers, faulty O-rings, or corroded valve seats, you can effectively address the problem and prevent further water loss.

This article will explore these common causes and provide step-by-step solutions to fix a running faucet.

Why Is the Water Still Running Even If It Is Shut Off?

Now that we have a basic understanding of faucet mechanics, let’s explore some of the common causes behind a faucet that continues to run even when it’s shut off.

• Worn-out Washer

Over time, the washer inside the faucet handle can deteriorate or damage it, resulting in a faulty seal. As a result, water may continue to seep even when the faucet is closed.

• Faulty O-ring

The O-ring, a small rubber ring, helps create a watertight seal between the spout and the faucet body. If the O-ring is worn, cracked, or incorrectly positioned, it can lead to water leakage and a running faucet.

• Corroded Valve Seat

The valve seat is the connection point between the faucet and the spout.

If it becomes corroded or damaged, it can prevent the faucet from closing correctly, allowing water to continue flowing.

• High Water Pressure

Excessively high-water pressure can strain the faucet’s internal components, leading to leaks and continuous water flow. 

• Malfunctioning Cartridge

If the cartridge becomes damaged or worn, it can result in a running faucet. Replacing the cartridge with a new one specific to your faucet model can resolve this issue.

• Plumbing System Issues

Sometimes, the problem may not lie within the faucet but in the plumbing system. Issues such as a faulty shut-off valve, a malfunctioning water pressure regulator, or a problem with the main water supply line can affect the functionality of your faucet.

How To Examine Faucet?

Here’s a guide on how to examine a faucet and ensure its proper functioning:

1. Turn off the Water Supply: Look for shut-off valves beneath the sink and turn them clockwise to shut off the water flow. If you can’t locate the shut-off valves, consider temporarily shutting off the main water supply to your home.
2. Inspect the Exterior: Look for any visible signs of damage, such as cracks, chips, or discoloration. Pay attention to the handles, spout, and other components for signs of wear or loose parts.
3. Check for Leaks: A small, slow leak can indicate an underlying issue. Run your fingers along the base of the faucet and underneath the sink to check for moisture. 
4. Test the Handles: If you encounter difficulty or stiffness while turning the handles, it may indicate a need for lubrication or repair.
5. Test the Water Temperature and Flow: Turn on the hot and cold handles and check the water temperature. Ensure that the hot water comes out from the designated handle and the cold water from the respective handle. 
6. Listen for Unusual Sounds: While the water is running, listen for any unusual sounds, such as rattling, grinding, or hissing, that may indicate loose or damaged components within the faucet.
7. Examine the Drain: Look for any signs of water pooling or slow drainage, as this could suggest a clogged drain or a faulty drain assembly that needs to be addressed.

How Long Should Water Run After Turning Off Main Valve?

Here’s a general guideline to follow:

• Single-Story Home: Let the water run for around 5 minutes for a single-story home is usually recommended. This allows enough time for the water to flush out of the pipes and for any remaining water to drain from the faucets.
• Multi-Story Home: In the case of a multi-story home, the process may take longer due to the additional floors and the vertical distance water needs to travel. Letting the water run for 10 to 15 minutes in this scenario is recommended.
• Long Water Pipes: If you have particularly long water pipes or your home is situated at the end of a water line, it may take longer for the water to drain thoroughly. In such cases, letting the water run for 15 to 20 minutes or even longer is advisable, ensuring all the water is flushed out.

It’s important to note that the above durations are general recommendations. Factors such as the size of the plumbing system, pipe insulation, and local water pressure can affect the required flushing time. 

What To Do If the Main Water Valve Won’t Shut Off?

First, inspect the valve for any obstructions hindering its proper closure. Clear away any debris, dirt, or mineral buildup blocking the valve’s movement.

If the valve is only partially closed and water is still flowing, try applying gentle pressure in the opposite direction to close it entirely. Avoid using excessive force to prevent damaging the valve. 

Additionally, if the valve is stiff or difficult to turn, applying a lubricant like WD-40 or a silicone-based lubricant can help loosen it.

Apply the lubricant to the valve stem and carefully turn the valve back and forth to distribute it. Using a wrench for extra leverage might help if the valve remains uncooperative. 

Place an adjustable wrench on the valve stem and turn it clockwise to close it, taking care not to overtighten and risk causing damage.

If none of these steps works, it’s time to seek assistance from a professional plumber with the expertise and specialized tools to handle more complex valve issues. 

Finally, if all else fails, you can locate the water meter and shut off the water supply at that point as a last resort.

Remember that this may require a unique tool provided by your water utility or the help of a plumber.
