Faucet Washers: Everything You Need To Know

What Are Faucet Washers?

Faucet washers are small rubber or silicone discs used in plumbing fixtures, such as faucets, to create a watertight seal and prevent leaks. They are typically placed between the faucet body and the valve stem or cartridge. When the faucet handle is turned off, the washer is compressed against the valve seat, blocking the flow of water. When the handle is turned on, the washer is lifted, allowing water to flow through the faucet. Over time, washers can wear out or become damaged, leading to leaks. Replacing the washer is a common maintenance task to ensure proper functioning of faucets and prevent water wastage.

Types Of Faucet Washers

There are several types of faucet washers commonly used in plumbing fixtures. Here are some of the most common types:

1. Flat washers: These are the most basic type of faucet washers and are typically made of rubber or neoprene. They have a flat surface and are used to create a watertight seal between the faucet body and the valve seat.
2. Beveled washers: These washers have a beveled edge, which allows them to create a tighter seal when compressed. They are often used in compression faucets where the washer is pressed against the valve seat to stop the water flow.
3. O-ring washers: O-ring washers are circular in shape and made of rubber or silicone. They are used in cartridge-style faucets and help create a watertight seal between the cartridge and the faucet body.
4. Cone washers: Cone washers have a conical shape and are commonly used in compression faucets. They are designed to compress evenly when the faucet handle is turned, creating a tight seal.
5. Friction ring washers: These washers have a textured surface that provides extra grip and helps prevent the faucet handle from slipping. They are often used in single-handle faucets to secure the handle in place.
6. D-shaped washers: D-shaped washers have a flat side and a curved side, resembling the letter "D." They are used in ball-type faucets to create a seal between the ball and the faucet body.

These are just a few examples of the different types of faucet washers available. The specific type of washer used will depend on the type of faucet and its design.

When You Need To Replace Faucet Washers?

Faucet washers typically need to be replaced when they become worn out or damaged. Here are a few signs that indicate it's time to replace faucet washers:

• Dripping or leaking: If you notice water dripping from the faucet even when it's fully closed, it's likely due to a worn-out washer. Replacing the washer can help stop the leak.
• Difficulty turning the faucet handle: If you find it increasingly difficult to turn the faucet handle, it could be a sign that the washer is deteriorating. Replacing the washer can restore smooth operation.
• Reduced water flow: A worn-out washer can restrict the water flow, resulting in reduced water pressure. If you notice a decrease in water flow from the faucet, it may be time to replace the washer.
• Visible wear or damage: Inspect the washer for any signs of wear, such as cracks, tears, or deformation. If the washer appears damaged, it's best to replace it to prevent further issues.

How To Replace Faucet Washers

To replace faucet washers on your own, you'll need to follow a few straightforward steps.

1. Locate the water supply valves situated on the wall beneath the sink to turn them off. In the case of a bathtub, if you cannot access the water supply valves, it is advisable to seek the assistance of a plumber.
2. To drain any water remaining in the pipes, turn both faucet handles to the "on" position.
3. Close the drain or use a cloth to cover it, ensuring that small parts do not accidentally fall down the drain.
4. Prepare a towel where you can place the disassembled parts in the order they were removed. This will facilitate the reassembly of the faucet later on.
5. Remove both handles or knobs by prying off the temperature cap (a plastic piece labeled with H or C) to expose the screw. Unscrew the screw and remove both the screw and the knob or handle.
6. With the removal of the knobs or handles, the valve stem will become visible. Utilize a wrench to loosen the locking nut and then take out the valve stem.
7. On the valve stem, you will find a screw, followed by a black washer, and beneath that, a white O-ring. Remove all of these components.
8. Take the old parts to the hardware store to ensure you obtain the correct replacement parts. If needed, seek assistance from someone in the plumbing aisle.
9. Apply plumbers grease to the valve stem and install a new O-ring and washer. Then, reattach the screw.
10. Reinsert the valve stem and reassemble the handles or knobs.
11. Turn the water supply lines back on.
12. Gradually turn on the water. If there are no leaks, the task is complete. However, if water sprays or there's still a leak, consider either restarting the process or contacting a local plumber for help.

Why Do Faucet Washers Need Replacing?

Most kitchen or bathroom faucets consist of two main components: the seat and washer. When the faucet is turned on, the washer is pressed against the seat, generating pressure, and as a result, water is forced out through the spout. Conversely, when the faucet is turned off, the washer seals tightly against the seat, preventing any water from flowing through.

Over time, washers can become worn and aged, leading to the loss of their ability to create a proper watertight seal, which can result in faucet leaks. If your faucet starts leaking, the first thing to investigate is whether the washer needs replacement. Fortunately, these washers are affordable and readily available at DIY or hardware stores, as well as online. They are usually sold in packs with various sizes, allowing you to find the right match for your existing washer.
