How to Change a Shower Faucet Washer: A Step-by-Step Guide
Is your shower faucet constantly dripping, even when it’s turned off? A worn-out washer is often the culprit. Replacing a shower faucet washer is a relatively simple and inexpensive DIY project that can save you water and money. This comprehensive guide will walk you through the process, step-by-step, ensuring a successful repair.
## Why Replace a Shower Faucet Washer?
* **Stop the Drip:** A leaky faucet wastes water and increases your water bill. Replacing the washer can eliminate the drip and save you money.
* **Prevent Further Damage:** A persistent drip can lead to mineral buildup and corrosion, potentially damaging the faucet and surrounding plumbing.
* **Extend Faucet Lifespan:** Replacing worn parts like the washer can prolong the life of your shower faucet.
* **Save Money:** Hiring a plumber for a simple washer replacement can be costly. Doing it yourself saves you money on labor costs.
## Tools and Materials You’ll Need
Before you begin, gather the following tools and materials:
* **New Faucet Washer:** The most crucial item. Take the old washer to a hardware store to ensure you get the correct size and type. There are various types of washers (flat, beveled, O-rings), so matching the existing one is vital.
* **Screwdrivers:** A set of screwdrivers, including both Phillips head and flathead, is essential.
* **Adjustable Wrench or Pliers:** Used to loosen and tighten nuts and bolts.
* **Penetrating Oil (Optional):** Can help loosen stubborn screws or nuts that are corroded.
* **Plumber’s Tape (Teflon Tape):** To seal threaded connections and prevent leaks.
* **Small Container or Towel:** To catch any water that may leak out.
* **Flashlight or Headlamp:** To provide adequate lighting.
* **Old Rags or Towels:** To protect the shower surface and clean up spills.
* **Valve Stem Puller (Optional):** May be needed if the valve stem is stuck.
## Safety First: Turning Off the Water Supply
Before you start working on your shower faucet, it’s crucial to turn off the water supply to prevent flooding. Here’s how:
1. **Locate the Shut-Off Valves:** The shut-off valves for the shower are usually located in one of these places:
* **Behind an access panel:** Often located behind the shower wall in an adjacent room (like a bedroom closet or hallway).
* **In the basement or crawl space:** If your plumbing is easily accessible.
* **Near the water meter:** This will shut off water to the entire house, but it’s a sure way to stop the flow to the shower.
2. **Turn Off the Valves:** Turn the valves clockwise until they are completely closed. Test the shower faucet to ensure the water is off. If water continues to flow, double-check that you’ve turned off the correct valves and that they are functioning properly. If shutting off the main water supply, inform other household members.
## Step-by-Step Guide: Replacing the Washer
Once you’ve gathered your tools and turned off the water supply, follow these steps:
**Step 1: Remove the Faucet Handle**
* **Locate the Screw:** Most shower faucet handles have a screw located either on the front of the handle, concealed under a decorative cap, or on the side of the handle. Use a small screwdriver or Allen wrench to remove the screw.
* **Remove the Handle:** Once the screw is removed, gently pull the handle straight off the faucet stem. If the handle is stuck, try wiggling it gently or using a handle puller (available at most hardware stores).
**Step 2: Remove the Faucet Escutcheon (Trim Plate)**
* **Identify the Escutcheon:** The escutcheon is the decorative plate that covers the faucet body where it meets the shower wall.
* **Remove the Escutcheon:** Some escutcheons are held in place by screws, while others are simply pressed on. If there are screws, remove them. If not, gently pry the escutcheon away from the wall. Be careful not to damage the wall or the escutcheon.
**Step 3: Remove the Valve Stem**
* **Locate the Packing Nut:** The packing nut is the large nut that holds the valve stem in place. It’s usually located behind the escutcheon.
* **Loosen the Packing Nut:** Use an adjustable wrench or pliers to loosen the packing nut. Turn the nut counterclockwise to loosen it.
* **Remove the Valve Stem:** Once the packing nut is loose, you should be able to pull the valve stem straight out of the faucet body. If the stem is stuck, try using a valve stem puller or applying penetrating oil to the threads and letting it sit for a few minutes before trying again. A valve stem puller attaches to the stem and allows you to apply force evenly, preventing damage.
**Step 4: Identify and Remove the Old Washer**
* **Locate the Washer:** The washer is usually located at the end of the valve stem, held in place by a screw or nut. It may be visibly worn, cracked, or disintegrated.
* **Remove the Screw or Nut:** Use a screwdriver or wrench to remove the screw or nut holding the washer in place. Be careful not to lose any small parts.
* **Remove the Old Washer:** Once the screw or nut is removed, you should be able to easily remove the old washer. Examine the washer closely to determine its size, shape, and type. This will help you find the correct replacement.
**Step 5: Install the New Washer**
* **Match the Washer:** Compare the new washer to the old washer to ensure they are the same size and type. Using the wrong washer can cause leaks or damage the faucet.
* **Place the New Washer:** Place the new washer in the same position as the old washer on the valve stem.
* **Secure the Washer:** Replace the screw or nut that holds the washer in place. Tighten it securely, but be careful not to overtighten it, as this could damage the washer or the valve stem.
**Step 6: Reassemble the Faucet**
* **Insert the Valve Stem:** Carefully insert the valve stem back into the faucet body. Make sure it is aligned properly.
* **Tighten the Packing Nut:** Tighten the packing nut with an adjustable wrench or pliers. Tighten it securely, but be careful not to overtighten it.
* **Wrap with Plumber’s Tape (Optional but Recommended):** Before reassembling the faucet, consider wrapping the threads of the valve stem with plumber’s tape (Teflon tape). This will help create a watertight seal and prevent leaks. Wrap the tape around the threads in a clockwise direction, overlapping each layer slightly.
* **Reattach the Escutcheon:** Reattach the escutcheon to the faucet body. Secure it with screws if necessary.
* **Reattach the Handle:** Reattach the handle to the valve stem. Secure it with the screw you removed earlier.
**Step 7: Test the Faucet**
* **Turn On the Water Supply:** Slowly turn the water supply back on by turning the shut-off valves counterclockwise.
* **Check for Leaks:** Carefully check the faucet and surrounding area for leaks. If you see any leaks, turn off the water supply and tighten the packing nut or check the washer installation. Retighten any connections that seem loose, and ensure plumber’s tape was applied properly. If leaks persist, you may need to replace the entire valve stem or call a plumber.
* **Test the Water Flow:** Turn on the shower faucet and check the water flow. Make sure the water flows smoothly and there are no drips when the faucet is turned off.
## Troubleshooting Common Problems
* **Faucet Still Drips:** If the faucet continues to drip after replacing the washer, there may be other issues, such as a damaged valve seat or a worn valve stem. In this case, you may need to replace the entire valve stem or consult a plumber.
* **Handle is Difficult to Turn:** If the handle is difficult to turn after reassembling the faucet, the packing nut may be too tight. Loosen the packing nut slightly until the handle turns smoothly. Applying a small amount of silicone grease to the valve stem can also help.
* **Can’t Remove the Valve Stem:** If the valve stem is stuck, try applying penetrating oil to the threads and letting it sit for a few minutes. You can also try using a valve stem puller. If you’re still unable to remove the valve stem, it’s best to call a plumber.
* **Stripped Screws:** Be careful when removing screws, as they can easily strip. Use the correct size screwdriver and apply steady pressure. If a screw is already stripped, you can try using a screw extractor or carefully drilling it out. If you are not comfortable with these methods, it’s best to call a plumber.
## Types of Shower Faucet Washers
Understanding the different types of washers can help you choose the correct replacement.
* **Flat Washers:** These are the most common type of faucet washer. They are flat and round, and they are typically made of rubber or neoprene.
* **Beveled Washers:** These washers have a beveled edge that helps create a tighter seal. They are often used in compression faucets.
* **O-Rings:** These are circular rings made of rubber or silicone. They are often used to seal connections between parts.
* **Specialty Washers:** Some faucets may use specialty washers that are designed for specific applications. These washers may have unique shapes or materials.
When replacing a washer, it’s important to match the old washer as closely as possible. Take the old washer to a hardware store to ensure you get the correct replacement.
## Preventative Maintenance
To prolong the life of your shower faucet and prevent future leaks, consider the following preventative maintenance tips:
* **Regularly Inspect Faucets:** Check your shower faucets and other faucets in your home for leaks. Address any leaks promptly to prevent further damage.
* **Lubricate Faucets:** Periodically lubricate the moving parts of your faucets with silicone grease. This will help keep them moving smoothly and prevent wear and tear.
* **Avoid Over-Tightening:** When tightening faucet handles or other parts, avoid over-tightening. Over-tightening can damage the faucet and lead to leaks.
* **Use a Water Softener:** If you have hard water, consider installing a water softener. Hard water can cause mineral buildup in your faucets, which can lead to leaks and other problems.
## When to Call a Plumber
While replacing a shower faucet washer is a relatively simple DIY project, there are times when it’s best to call a plumber.
* **You’re Not Comfortable with Plumbing:** If you’re not comfortable working with plumbing, it’s best to leave the job to a professional.
