Turning Off the Water Supply: How To Repair A Dripping Bathroom Faucet
Before you start disassembling the faucet, you need to turn off the water supply to prevent flooding and ensure a safe working environment.
The shut-off valve controls the water flow to your bathroom faucet. It’s typically located near the faucet, either under the sink or on the wall behind it. It might be a simple knob, a lever, or a gate valve, depending on the age and type of your plumbing system.
Identifying the Shut-Off Valve
The shut-off valve is usually a small, metal valve with a handle or lever. You can identify it by looking for a pipe that leads directly to your faucet. The valve will be connected to this pipe, and it might have a label indicating its purpose.
Operating the Shut-Off Valve Safely, How to repair a dripping bathroom faucet
- Locate the valve: Look for a small, metal valve with a handle or lever connected to the pipe that leads to your faucet.
- Turn the valve: Turn the valve clockwise to shut off the water supply. You’ll feel resistance as you turn the valve. The valve will usually have a stop position where it feels tight.
- Check for water flow: Once you’ve turned the valve, turn on the faucet to check if the water flow has stopped. If there’s still water flowing, try turning the valve a little further. If the water doesn’t stop, you might have a problem with the valve itself.
If you can’t find the shut-off valve, you might have to turn off the main water supply to your house. This is usually located in the basement or near the water meter. Be sure to consult your homeowner’s manual or a qualified plumber if you are unsure about the location or operation of the main water supply.
Visual Illustration of the Shut-Off Valve
Imagine a small, round valve with a lever on top. The lever is attached to a shaft that runs through the center of the valve. When you turn the lever clockwise, the shaft moves inside the valve, blocking the flow of water. The valve might have a small, square nut on the side, which can be used to tighten or loosen the valve.
Disassembling the Faucet
Now that you’ve shut off the water supply and gathered your tools, it’s time to take apart the faucet. This process may vary slightly depending on the type of faucet you have, but the general steps are the same.
Removing the Handle
The first step is to remove the handle. This is usually done by unscrewing a small screw or cap that is located on the top or side of the handle. Once the screw is removed, you should be able to pull the handle off.
Removing the Cartridge
The cartridge is the heart of the faucet, and it’s responsible for controlling the flow of water. To remove the cartridge, you’ll need to remove the handle first. The cartridge is typically held in place by a retaining clip or nut. Use a wrench or pliers to loosen the clip or nut, and then gently pull the cartridge out.
Removing Other Components
Depending on the type of faucet, there may be other components that need to be removed. For example, some faucets have a spout that needs to be unscrewed, and others have a decorative escutcheon that needs to be removed.
Be sure to note the order in which you remove the parts, so you can reassemble the faucet correctly later.
Inspecting and Replacing Worn Parts
Now that you have disassembled the faucet, it’s time to inspect the components for wear and tear. Identifying and replacing worn parts is crucial for stopping the drip and ensuring your faucet functions smoothly.
Inspecting for Wear and Tear
Start by inspecting the faucet’s internal components, focusing on areas that experience friction and water pressure. Look for signs of wear, such as:
- Worn Washers: The washer is a small rubber or plastic disc that sits on the valve stem and creates a seal to stop the water flow. Look for cracks, tears, or a flattened surface, which indicate the washer needs replacement.
- Damaged O-Rings: O-rings are small rubber rings that provide a seal between moving parts. Check for cracks, cuts, or a loss of elasticity, which can cause leaks.
