What Causes a Leak in The Bathroom Faucets?

1. Excessive Water Pressure
The excessive flow of water through the pipelines into the faucet is a basic cause of a bathroom faucet leaking at the base.
You need to balance or lower the water pressure to stop this leakage.
2. A Broken Internal Faucet Cartridge
Double-handle faucets help in an outflow of hot and cold water. These are known as cartridge-style faucets.
The purpose of this cartridge is to maintain the water pressure from each spout. Any internal damage to this cartridge will cause water to leak out.
3. Broken Washers
A washer is a round rubber disc that rests on the valve seat. It acts as a seal in the faucet. However, due to regular friction, this rubber disc gets damaged.
Occasionally, the wrong size washer might be used to create the seal. Such situations are common causes of a bathroom faucet leaking at the base.
4. A Broken Internal O-Ring
The O-ring is a small disc attached to the stem screw. It is responsible for holding the handle in place. You will find the bathroom faucet leaking at the base when the O-ring erodes over time.
With a damaged o-ring, water leaks out from the base of a bathroom faucet every time you turn it on.
5. Damaged Valve Seat
A damaged valve seat is the most common cause of leakage from the spout of a bathroom faucet. The valve seat helps connect the faucet and the spout.
However, with everyday usage over the years, sediments accumulate on the valve seat, causing corrosion or damage.
This damage to the valve seat will cause water to leak out of the tap.

How to Fix a Bathroom Faucet Leaking at The Base
Speaking specifically about the bathroom faucet leaking at the base is hard to spot. This is a junction where the faucet rests on the sink.
This form of leakage happens only when the tap is on, which makes it even more tricky to notice the leak.
However, two specific causes lead to a leaky bathroom faucet. One is a damaged O-ring, and the other is a damaged internal cartridge. Let us fix one leakage at a time.
Change the Internal O-Ring in your Bathroom Faucet
Continuous friction over years of usage erodes the O-ring. It is the first cause that leads to a bathroom faucet leaking at the base.
You will need a set of screwdrivers, pliers, wrenches, and replacement O-rings to start the repair process.
Let us now proceed step-by-step.
1. Stop the Water Supply
Begin by closing the valve under your sink that allows continuous water supply through the faucet.
Without stopping the water, you will not be able to repair anything and will end up with an indoor water spill.
Therefore, rotate these valves in clockwise directions to limit the water flow first. Then open the tap and let any remaining water drain through the faucet.
2. Pull out The Faucet Handle Cap
Now, bring out your screwdriver. Place the head of the screwdriver underneath the faucet handle. A little push will help pop the handle cap out of its place.
Once you remove the faucet handle cap, you can access the screw connecting the stem and the handle.
3. Remove the Screw Cap Handle
Your screwdriver will be your best friend in this process! Now you need to grab the handle connected to the stem and pull it up to separate from the valve stem.
You might also remove any other decorative caps that limit a straightforward repair of a bathroom faucet leaking at the base.
4. Detach the Value From The Faucet
Once you remove the crew cap, it is time to grab a wrench or pliers of your choice. With the help of a wrench, rotate the valve base in an anti-clockwise direction.
After a few rounds, you will feel the valve detach from the faucet body.
5. Replace the O-rings
Moving forward, you will locate the old, worn-out O-ring on the faucet body. All you have to do now is replace this damaged O-ring with a new one.
Make sure to choose the correct size, and you are done!
6. Assemble back everything
The final step is to assemble all the parts one after the other back to their old positions. Start by sliding the valve back into the faucet body.
Do not forget to use a wrench to tighten these parts. Now put the faucet handle back over the valve stem and fix the pop cap back to its position.
Hurray! You changed a damaged O-ring and fixed a bathroom faucet leaking at the base all by yourself. Now, turn on the faucet to check if the leak is repaired.
If not, chances are there is damage to the internal cartridge as well.
Change the Internal Faucet Cartridge
The other reason your bathroom faucet is leaking at the base could be a damaged cartridge. The cartridge is a metal or plastic piece responsible for controlling the water flowing from the tap.
If you have a double-handle faucet, each one will have different cartridges.
It is thus necessary to determine which of the two faucet cartridges has damage resulting in leakage. If the left cartridge is damaged, you can replace the same and leave the right cartridge unbothered.
To proceed with this repair process, you will need an Allen wrench, a pipe wrench, flathead screwdrivers, penetrating oil, and new cartridges.
1. Stop the Water Supply
Similar to the previous process of changing an O-ring, start by stopping the water supply. Rotate the valves under your sink in an anti-clock direction and limit the water flow before getting to work.
You must let the faucet on to drain the remaining water and double-check before spilling water all over the floor.
2. Pull out The Faucet Handle
Once you have stopped the water flow, it is time to pull out the faucet handle. Look for the screws at the rear that hold the handles in place. In many cases, a stylish faucet has decorative screw caps.
You will need the screwdriver to pop out these screw caps and then access the screws to pull out the handle.
3. Detach the Retaining Nut
The third step in repairing a bathroom faucet that leaks at the base is to locate the retaining nut. Loosen the retaining nut from the top of the cartridge with the help of a pipe wrench.
Once you remove the nut successfully, keep it aside, as it will help hold the new cartridge in place.
4. Remove and Replace the Broken Cartridge
As you remove the retaining nut, you can now pull out the damaged cartridge. Note how the cartridge is placed and secured.
Now, take the new replacement cartridge and put it back in its rightful position with the help of the previously removed retaining nut.
Use little penetrating oil to grease the cartridge and the screw for an easy fixture.
5. Assemble Back Everything
Assemble everything back into its place one after the other, following how you opened the whole faucet. Now it is time for a final check.
Turn on the valve for the water supply, open it, and leave your faucet on. You have now successfully fixed a bathroom faucet leaking at the base.
