Understanding the Mechanics of a Faucet
Before we examine why a faucet drips, we should understand how it works. Faucets, no matter how they are made, have a simple and important job. They manage the flow of water from the water supply to your sink or basin.
Faucets have parts like valves, washers, and seals. These parts allow you to adjust the water flow and temperature. This careful arrangement of parts keeps a strong seal when the faucet is not in use and provides a steady flow when it is in use.
If this system gets broken, usually from use or build-up of minerals, it can lead to annoying drips.
How Faucets Work: The Basics
Faucets work by using a valve to block the water flow. When you turn the faucet handle, the valve opens up. This lets water come out through the spout. Inside the faucet, the valve seat is a small hole that is very important for this to happen. When you turn the faucet off, a washer presses against the valve seat. This makes a seal that stops water from leaking out.
The amount of water that flows out depends on how much you turn the handle. This controls how the valve operates. There are different kinds of faucets, like compression, cartridge, ball, and ceramic disc faucets. They all work in slightly different ways, but the basic idea is the same. Understanding this simple operation can help you find a leak and pick the right way to fix it.
Types of Faucets Common in Homes
California homes usually have various types of faucets. Each type has its unique features.
- Cartridge Faucets: These faucets have two handles. One is for hot water and the other is for cold. You often find them in bathrooms. They use a cartridge that keeps all the moving parts together, which helps with water flow and temperature.
- Ball Faucets: You can usually see these in kitchens. They have a single handle on a rounded cap. This design makes it easy to control water flow and temperature. Inside, a ball joint allows the handle to move smoothly, mixing hot and cold water.
- Ceramic Disc Faucets: These faucets are popular because they are strong and modern-looking. They use two ceramic discs to manage water flow. You can find them in kitchens and bathrooms. Knowing which type of faucet you have can help you fix any leaks.
Common Causes of Dripping Faucets
Now that you understand how a faucet works, let's discuss what usually makes those annoying drips happen.
A leaky faucet can happen for several reasons. Old parts may be one cause. A buildup of minerals can also lead to leaks.
Worn Out Washers and Seals
A common reason for a dripping faucet is a worn washer. This small rubber piece is inexpensive and keeps water from leaking when the faucet is turned off. Over time, it can wear down, crack, or get loose because it rubs against the valve seat. This leads to leaks. Other parts, like O-rings, can also wear out and cause dripping. The good news is that you can replace these parts easily by yourself. This simple faucet repair can help you save money and gallons of water.
Corroded Valve Seats
The valve seat is the part where the faucet and spout connect. It can break down because of minerals in the water. Over time, things like calcium and lime can build up on the valve seat. This buildup creates bumps that stop a tight seal from being made. Because of this, you might notice a dripping faucet, even when the faucet handle is completely closed. If you see a white, crusty growth around the faucet spout or handle, the worn valve seat could be causing the problem.
O-Ring Issues
The O-ring is a small rubber ring that looks like a donut. It is important to prevent leaks around the faucet handle. You can find the O-ring inside the faucet stem. It seals the area and stops water from leaking out near the stem screw. Like washers, O-rings can wear down, crack, or become loose over time. This can lead to leaks around the faucet handle. The good news is that replacing a worn-out O-ring is simple and not expensive.
Incorrect Water Pressure Settings
High water pressure is not the main reason, but it can cause a dripping faucet. When the water pressure is very high, it can put a strain on the faucet parts. This strain can make washers, seals, and other parts wear out quickly. The right water pressure for your home should be between 40 and 60 psi (pounds per square inch).
If you feel your water pressure is too high, you should contact a plumber. They can look at it and make any needed adjustments. Reducing high water pressure helps to protect your faucets and is also better for your plumbing system.
When to Call a Professional Plumber
Many dripping faucet repairs are easy. You can fix them using a few tools from the local hardware store. But, some problems need a plumber. Trying to fix tough issues without skill can make things worse. This can cause more damage and cost more money.
Knowing when to call a professional is important for keeping your plumbing system in good shape for a long time.
Signs That You Need Professional Help
If you notice any of these signs, you should call a skilled plumber.
- Low water pressure: A dripping faucet with low water pressure may mean there is a more serious problem. This could be a hidden leak or a problem with the main water supply line.
- Multiple leaky faucets: A single leaky faucet might be fine, but if you have many in your home, there may be a larger issue. This often means there is high water pressure or pipes that are damaged.
- Unsuccessful DIY repairs: If you tried to fix the leaking faucet but it still drips, you should call a professional. They have the right tools and skills to fix tough plumbing issues.
Choosing a Reliable Plumber
Finding a trustworthy plumber is very important for any homeowner. Here’s how to get through the process:
- Ask for Recommendations: Start by talking to friends, family, or neighbors for suggestions. They can share their experiences with local plumbers.
- Read Online Reviews: Look at review sites like Yelp, Google, and Angie's List to see what people say about the plumbers’ work and their satisfaction.
- Check Credentials: Make sure the plumber has a license and insurance and is bonded. This helps protect you if something goes wrong.

Frequently Asked Questions
How do you fix a faucet that keeps dripping?
Fixing a dripping faucet is usually easy. First, turn the main water supply off. Then you can take the faucet apart and replace worn-out parts, like the rubber washer, O-ring, or packing nut. Cleaning the valve seat with white vinegar can help as well. If you feel unsure, it is better to call a plumber.
What is the most common cause of a dripping faucet?
The main cause of a dripping faucet is a worn washer. Over time, the washer gets weaker. It can’t make a tight seal against the valve seat, which results in water dripping. Other problems may come from water pressure or issues with the faucet handle.
Why does my faucet drip after I turn it off?
If your faucet drips after you turn it off, it is usually because some parts are worn out. This can be washers, O-rings, or a damaged valve seat. When these parts are damaged, they cannot stop the water pressure. This makes the water drip slowly, even when the faucet handle is turned off.
Why does a tap suddenly start dripping?
A sudden drop in water from your tap can happen for several reasons. One reason might be high water pressure. It could also be due to dirty buildup on the valve. Sometimes, there are issues with the O-ring. Worn-out washers can also cause a sudden drip.
How does wear and tear affect the likelihood of a faucet dripping?
Water fixtures, like faucets, can break down as time passes. Parts such as washers, O-rings, and valve seats become old and weak. As they age, they may break more easily. This can lead to a faucet dripping because the worn parts cannot stop the water pressure.
