A dripping faucet isn't just annoying; it's a money waster. According to the EPA, leaks can account for more than 10,000 gallons of water wasted every year in the average home. That’s enough water to wash nearly 300 loads of laundry! The good news is that fixing a leaky faucet is often a simple DIY project, especially when the culprit is a worn-out washer. This guide will walk you through the process of replacing a faucet washer, saving you money and water.
Understanding Your Faucet Type
Before you start, it's crucial to identify the type of faucet you're dealing with. The repair process varies slightly depending on the faucet type. The most common types are:
- Compression Faucets: These are the oldest and simplest type, with separate hot and cold handles. They rely on a rubber washer being compressed against the valve seat to stop water flow.
- Cartridge Faucets: These have a single handle that controls both temperature and water flow. The handle moves a cartridge up and down to regulate the water.
- Ball Faucets: Similar to cartridge faucets, ball faucets also use a single handle. They feature a ball valve with slots and chambers that control the mixing and flow of water.
- Ceramic Disc Faucets: These are the most modern and durable type, also using a single handle. They employ two ceramic discs that slide over each other to control water flow.
This guide focuses on compression faucets, as washer replacement is the most common repair for this type. However, many of the initial steps are applicable to other faucet types as well.
Why Compression Faucets Leak (and Why Washers Matter)
Compression faucets are prone to leaks because the constant compression of the rubber washer against the valve seat causes it to wear down, crack, or become deformed over time. This creates gaps that allow water to seep through, resulting in the dreaded drip. Replacing the worn washer is a straightforward fix that can restore the faucet's functionality.
Tools and Materials You'll Need
Gather these tools and materials before you begin:
- New Faucet Washers: Take the old washer with you to the hardware store to ensure you get the correct size and type. It’s best to buy a variety pack of different sizes and materials.
- Screwdrivers: Both flathead and Phillips head screwdrivers are often needed.
- Adjustable Wrench or Basin Wrench: Used to loosen and tighten nuts and connections. A basin wrench is especially helpful for reaching nuts in tight spaces under the sink.
- Penetrating Oil (e.g., WD-40): To loosen stubborn nuts and screws.
- Pliers: For gripping and removing small parts.
- Old Cloths or Towels: To protect the sink and catch any water.
- Small Container or Bowl: To hold small parts as you disassemble the faucet.
- Plumber's Grease: To lubricate the new washer and prevent future corrosion.
- Optional: Valve Seat Wrench or Tool: To resurface or remove a damaged valve seat.
Pro Tip: Consider purchasing a faucet repair kit that includes an assortment of washers, O-rings, and other small parts commonly needed for faucet repairs. This can save you time and multiple trips to the hardware store.
Step-by-Step Guide to Replacing a Faucet Washer
Follow these steps to replace the washer in your compression faucet:
- Turn Off the Water Supply: This is the most important step! Locate the shut-off valves under the sink for both hot and cold water. Turn them clockwise until they are completely closed. If you can't find shut-off valves under the sink, you'll need to turn off the main water supply to your house.
- Open the Faucet to Relieve Pressure: After turning off the water, open both the hot and cold water faucets to release any remaining pressure in the lines. Let the water drain completely.
- Protect the Sink: Place an old cloth or towel in the sink to prevent scratches and dings.
- Disassemble the Faucet Handle:
- Remove the Decorative Cap: Most compression faucets have a decorative cap on the handle that conceals a screw. Use a small flathead screwdriver or a knife to gently pry off the cap.
- Loosen the Handle Screw: Use the appropriate screwdriver (flathead or Phillips head) to loosen and remove the screw.
- Remove the Handle: Gently pull the handle straight up and off the faucet stem. If it's stuck, try wiggling it slightly while pulling.
- Remove the Packing Nut: Using an adjustable wrench or basin wrench, loosen the packing nut that holds the faucet stem in place. Turn the nut counterclockwise to loosen it.
- Remove the Faucet Stem: Once the packing nut is loose, carefully pull the faucet stem straight up and out of the faucet body.
- Locate and Remove the Old Washer: At the base of the faucet stem, you'll find the old washer. It may be held in place by a screw or a nut. Use a screwdriver or pliers to remove the screw or nut and detach the old washer. Pay attention to how the washer is oriented.
- Install the New Washer: Place the new washer in the same position as the old one. Secure it with the screw or nut. Make sure the washer is seated properly and the screw or nut is tightened securely, but not overtightened.
- Inspect the Valve Seat: This is the surface inside the faucet body that the washer presses against to stop the flow of water. Inspect the valve seat for any signs of damage, such as corrosion, pitting, or mineral buildup. If the valve seat is damaged, it can prevent the new washer from sealing properly.
- Clean the Valve Seat: Use a valve seat dressing tool to smooth out minor imperfections. Insert the tool into the faucet body and rotate it to grind down the surface of the valve seat.
- Replace the Valve Seat: If the valve seat is severely damaged, you may need to replace it. Valve seats are typically threaded or pressed into the faucet body. Use a valve seat wrench or a specialized tool to remove the old valve seat and install a new one.
- Lubricate the Washer: Apply a small amount of plumber's grease to the new washer to help it seal properly and prevent future corrosion.
- Reassemble the Faucet: Carefully reinsert the faucet stem into the faucet body. Tighten the packing nut securely, but not overtightened. Replace the handle and secure it with the screw. Snap the decorative cap back into place.
- Turn the Water Supply Back On: Slowly turn the shut-off valves under the sink counterclockwise to restore the water supply.
- Check for Leaks: Open the faucet and check for leaks around the handle, spout, and under the sink. If you see any leaks, tighten the packing nut slightly or check the connections under the sink.
Dealing with Stubborn Parts
Sometimes, faucet parts can be difficult to remove due to corrosion or mineral buildup. Here are some tips for dealing with stubborn parts:
- Use Penetrating Oil: Apply penetrating oil (like WD-40) to stubborn screws, nuts, and stems. Let it sit for a few minutes to help loosen the corrosion.
- Apply Heat: Gently heating a stuck nut or screw with a heat gun or hair dryer can help to expand the metal and break the bond of corrosion.
- Use a Rubber Mallet: Gently tapping the faucet handle or stem with a rubber mallet can help to loosen it.
- Don't Force It: If a part is extremely stuck, don't force it. You could damage the faucet or break the part. Consider calling a plumber for assistance.
Advanced Tips and Tricks
Choosing the Right Washer Material
Faucet washers are typically made from rubber or neoprene. Rubber washers are more common and are suitable for most applications. Neoprene washers are more resistant to chemicals and high temperatures, making them a good choice for faucets that are exposed to harsh water conditions.
Resurfacing the Valve Seat
As mentioned earlier, a damaged valve seat can prevent the new washer from sealing properly. If the valve seat is only slightly damaged, you can resurface it using a valve seat dressing tool. This tool will grind down the surface of the valve seat and remove any imperfections.
Replacing the Entire Faucet Stem
If the faucet stem is severely corroded or damaged, it may be easier to replace the entire stem instead of just the washer. Faucet stems are available at most hardware stores. Make sure to purchase a stem that is compatible with your faucet model.
Preventing Future Leaks
Here are some tips for preventing future faucet leaks:
- Use Plumber's Grease: Apply plumber's grease to all moving parts of the faucet, including the washer, stem, and packing nut. This will help to lubricate the parts and prevent corrosion.
- Don't Overtighten: Overtightening nuts and screws can damage the faucet and cause leaks. Tighten the parts until they are snug, but not excessively tight.
- Replace Washers Regularly: Replace faucet washers every few years, even if they don't appear to be damaged. This will help to prevent leaks before they start.
When to Call a Plumber
While replacing a faucet washer is a relatively simple DIY project, there are times when it's best to call a plumber. Consider calling a plumber if:
- You're not comfortable working with plumbing.
- You can't identify the type of faucet you have.
- You're unable to turn off the water supply.
- The faucet is severely corroded or damaged.
- You've tried replacing the washer and the faucet is still leaking.
A qualified plumber can quickly diagnose the problem and make the necessary repairs. They can also help you choose a new faucet if your old one is beyond repair.
