How to solve the bathroom faucet is always dripping

Posted on April 02 2022

Water dripping from bathroom faucets is the most common problem with plumbing and one of the easiest to repair. However, many people ignore this problem and do not repair dripping bathroom faucets without realizing that this may waste a lot of money. Continuous dripping will waste a lot of water charges in a short time. Multiply the wasted water cost of each bathroom faucet by the number of bathroom faucets that drip in your home, and you can figure out how much money you are "flowing" into the sewer. And dripping water from hot bathroom faucets can waste even more because you pay to heat the water before it flows into the sewer.

How to solve the problem of dripping water from the bathroom faucet? The dripping water is caused by the leakage of the water supply. Don't forget that the water supply enters your home after being pressurized, so when the bathroom faucet handle is in the "off" position, an impervious gasket must be used to block the incoming water. This gasket is usually formed by pressing the gasket tightly against the bathroom faucet seat. Obviously, if something goes wrong with the washer or bathroom faucet, some water can leak out and drip out of the bathroom faucet. To prevent such a bathroom faucet from dripping, you usually just need to replace the gasket or repair the bathroom faucet seat.

How to repair dripping water from the bathroom faucet? The first thing you need to do is to turn off the water supply. You should only need to turn off a water supply valve near the bathroom faucet to turn off the water supply, but if not every bathroom faucet in your house is equipped with a water supply valve, you have to turn off the main water supply valve to turn off all of your home Water supply.

Solve the bathroom faucet dripping one: Press the bathroom faucet

No matter what appearance the push-on bathroom faucet has, whether it has two handles for hot and cold water or only one handle that controls hot and cold water at the same time, it works according to some basic principles. Here's how to take down a push-on bathroom faucet and fix the drip problem:

Required tools: Use these tools to deal with push-on sanitary faucets—screwdrivers, penetrating lubricants, carp tongs or adjustable wrenches and the pads to be replaced.

Step 1: Turn off the water supply, remove the small screws above or behind the handle of the bathroom faucet to remove the handle fixed on the body of the bathroom faucet. Some screws are hidden under metal buttons, plastic buttons, or plastic pieces that snap or screw into the handle. As long as you open the button, you will see the top handle screw. If necessary, use some penetrating lubricant like WD-40 to loosen the screws.

Step 2: Remove the handle and look at the parts of the bathroom faucet. Use a large carp pliers or adjustable wrench to remove the packing nut, being careful not to leave scratches on the metal. Turn the spool or shaft in the same direction as when you turned on the bathroom faucet to unscrew them.

Step 3: Remove the screws holding the washers. If necessary, use penetrating lubricant to loosen the screws. Inspect the screws and spools and replace if damaged.

Step 4: Replace the old gasket with an identical new gasket. New washers that almost match the old washers generally keep bathroom faucets from dripping. You'll also notice if the old gasket has a bevel or flat, and replace it with the same new gasket. A washer designed for cold water only expands violently when hot water flows through it, blocking the water outlet, making the hot water flow slower. Some gaskets work in hot and cold water, but you need to make sure that the gasket you buy for replacement is exactly the same as the original one.

Step 5: Fix the new gasket to the valve core, and then reinstall the parts in the bathroom faucet. Rotate the spool clockwise. After the spool is in place, reinstall the packing nut. Be careful not to leave scratches on the metal with the wrench.

Step 6: Reinstall the handle and replace the button or disc. Turn the water supply back on and check for leaks.

Solve the bathroom faucet dripping two: bathroom faucet valve seat

If you change the gasket and the bathroom faucet still drips, there may be a problem with the valve seat of the bathroom faucet. A damaged gasket may cause the valve seat of the sanitary faucet to be worn and flattened by the metal spool, or the deposition of chemicals in the water may form a residue, which prevents the gasket from fully pressing against the seat.

How to repair a broken bathroom faucet? Of course, you can replace the entire bathroom faucet. Another option is to just replace the bathroom faucet. If you have the right tool—called a seat wrench, then removing the old seat is a simple matter. Insert the seat spring wrench into the seat, and then pull it counterclockwise. Once you remove the old seat, make sure that the new seat you buy is exactly the same as the original. If the seat cannot be removed, insert a seat cover that slides into place on the old seat and provides a seal. Two types of seat rollers or sanders that can flatten worn valve seats.

Another option is to use a seat roller or sander, which is an inexpensive tool that can flatten worn valve seats. When using this tool, be careful not to use it for too long or use too much force, because the valve seat is made of soft metal, and you can easily wear it off too much.

When using the sander, first remove the valve of the sanitary faucet, and insert the valve seat roller down into the valve seat in the sanitary faucet body. Rotate the tool clockwise several times with moderate force. Then wipe off any metal shavings from the valve seat with a cloth.

Solve the bathroom faucet drip three: seal ring of the bathroom faucet

Water dripping occurs when the bathroom faucet is turned off; water leakage occurs when there is water flowing in the bathroom faucet. If you see water coming out of the handle, your bathroom faucet is leaking; the first thing to do is to make sure that the packing nut of the bathroom faucet is tight, but be careful not to scratch the nut with pliers or wrenches.

The following are the tools you need to replace the bathroom faucet seal: adjustable wrench, replacement bathroom faucet seal, vaseline.

If you find that the cause of the leak is not that the nut is loose, you need to replace the seal. The sealing ring of the bathroom faucet can be a tight piece of sealing ring composed of one or more O-shaped rubber rings, or it can be something like a string or soft metal wire wound around the valve core under the packing nut.

When replacing the bathroom faucet seal, follow the steps below:

Step 1: Turn off the water supply and remove the bathroom faucet handle.

Step 2: Unscrew the packing nut, and remove the nut and the old seal from the valve core.

Step 3: Install a new seal. If you are using a linear sealing material, wrap it around the spool a few times. In the case of a sealing material such as soft metal wire, it is wound only once around the spool.

涂 Before you reassemble the bathroom faucet, apply a thin layer of petroleum jelly to the threads of the valve plug and the threads of the packing nut.

Solve the drip of bathroom faucets

The kitchen faucet has one or more O-rings to prevent water from flowing around the water outlet. If the O-ring is worn out, every time you open the bathroom faucet, you will see water flowing out of the bottom of the water outlet.

The following are the tools needed to replace the O-ring: adjustable wrench, water pipe joint tape, replacement O-shaped.

Steps to replace O-ring:

Step 1: Turn off the water supply, turn it counterclockwise and remove the threaded coupling nut that fixes the water outlet. Be sure to wrap the nut with tape to prevent it from being scratched by pliers or wrenches.

Step 2: After removing the coupling nut, lift the water outlet up and take it out of the outlet seat. You can see these rings inside the outlet seat.

Step 3: Replace the problematic ring with a new ring of exactly the same size. Reassemble the bathroom faucet.

Through the above methods, the problem of dripping water from the bathroom faucet has been basically solved. I hope it will be helpful to everyone.
