Diagnosing the Problem

The first step to fixing your leaking bathroom faucet is to correctly diagnose the problem. You should look at the area surrounding the base of the faucet for signs of water damage or corrosion. If there is visible damage to the base, then you will likely need to replace the entire faucet. However, if there is no visible damage, then the leak is likely caused by a faulty valve or O-ring and can be fixed more easily.

Preparing To Repair the Faucet

Before attempting any repairs, you should turn off the water supply to the faucet. This will prevent further damage and ensure that you don’t get injured while making repairs. Once the water is off, you should gather all of the necessary tools – these may include a moen replacement cartridge, an adjustable wrench, channel locks, screwdrivers, etc. You may also want to cover any exposed surfaces with towels or a plastic tarp in case any leaks or spills occur while you are working.

Removing the Faucet

Once you have all of your supplies ready, you can start removing the faucet. To do this, you should use an adjustable wrench or channel locks to loosen and remove the nuts holding the faucet in place at the base. Once these nuts are removed, you should be able to lift the faucet from its base plate and set it aside for now. 

Troubleshooting a Leaky Valve

Next, you can examine the valve and O-rings underneath the faucet for signs of wear or damage. If there are worn out or cracked O-rings, then they can be replaced with new ones from a hardware store. If there is any corrosion on the valve seat or moen cartridge, then these should be replaced as well. 

Installing a New Valve 

To install a new valve cartridge, you first need to remove all of the old components from inside the valve body using an adjustable wrench or channel locks. Once all of these components are gone, you can insert the new valve cartridge and secure it with screws.

Reassembling the Faucet 

Once all of your repairs are finished, and you’ve double-checked your work, you can reassemble your faucet by placing it back onto its base plate and securing it with nuts as before. If you had any plastic washers between your faucet and base plate then make sure they are properly reinstalled before securing everything in place.

Testing the Finished Repair 

Finally, after reassembling your faucet you can turn on the water supply again and test if your repair has been successful by checking to see if any leaks occur around the base after running it for several minutes. Further, make sure that no water is leaking out around any of the valves or O-rings. If everything looks good then congratulations – you have successfully repaired your leaking bathroom faucet!
