Why Is My Single Lever Faucet Dripping Even With the Water Turned Off?
If your single lever faucet is dripping even when the water is turned off, it could be due to a few reasons.
The most common cause of this issue is worn-out rubber seals or washers inside the faucet.
Over time, these parts can wear out and lose their ability to create a tight seal against the valve body, resulting in a slow drip.
In order to fix this issue, you will need to replace the seals or washers inside the faucet.
Another potential cause for a single lever faucet that is dripping even when the water is turned off could be a damaged valve seat.
The valve seat is the flat metal surface against which the seal or washer creates a tight seal.
If this surface becomes worn out or corroded, it can create small gaps between the seat and seal that allow water to leak through when the handle is closed. Replacing the valve seat will solve this issue.
Finally, if none of these solutions work, then it could be due to a faulty cartridge inside your single lever faucet.
The cartridge contains the internal mechanism that controls the water flow and if it becomes damaged, it can prevent the valve from completely shutting off the water when you turn off the handle. Replacing your faucet’s cartridge will solve this issue.
No matter what is causing your single lever faucet to drip, replacing seals or washers, repairing or replacing a valve seat, or replacing a faulty cartridge should fix this issue and stop the dripping for good.
If any of these solutions seem too difficult for you to tackle yourself, reach out to a professional plumber who can help you repair your faucet quickly and efficiently.

Why Is My Faucet Still Dripping After Changing the Cartridge?
In some cases, a dripping faucet after replacing the cartridge is due to improper installation or incorrect parts used in the repair.
If you are not comfortable with repairing your own faucet or if you don’t have the right tools and supplies, it may be best to hire a professional plumber to do the job correctly.
To rule out other possible causes of the drip, check if there are any damaged O-rings or seals in the faucet and replace them as needed.
You should also make sure that all connections are secure and tightly closed, as loose connections can cause leaks around the cartridge.
Lastly, make sure that no air is getting into the system by bleeding air from the system according to manufacturer instructions.
Conclusion
If your single lever faucet is dripping even with the water turned off, it may be due to a broken O-ring or washer.
If you have changed the cartridge and the faucet is still dripping, it could be because the seat isn’t tight enough or there may be Sediment build-up in the valve.
In both cases, it’s best to call a plumber to take a look and fix the issue. Have you had any issues with your single lever faucets?
