DIY Guide: Changing A Tap Washer To Stop Leaks

Hey guys! Ever dealt with that annoying dripping tap? It's not just irritating; it's wasting water and money! The good news is, most of the time, fixing a leaky tap is something you can totally handle yourself. And guess what? Often, the culprit is a worn-out tap washer. In this comprehensive guide, we're going to walk you through exactly how to change a tap washer, step by simple step. So, grab your tools, and let's get started!

Why is My Tap Leaking?

Before we dive into the how-to, let's briefly chat about why taps leak in the first place. Understanding the cause can help you prevent future issues. There are several reasons why a tap might leak, but with compression-style faucets, those classic two-handled taps you often see, the issue is frequently a worn tap washer. These washers are small, rubbery or fiber discs that sit at the base of the tap valve. When you turn the tap off, the washer presses against the valve seat, creating a watertight seal. Over time, the constant pressure and friction can cause these washers to wear down, become brittle, or even crack. This leads to gaps in the seal, and voilà, you've got a drip! Other types of faucets, such as ball, ceramic disk, and cartridge faucets, have different mechanisms and may leak for different reasons, but this guide specifically focuses on compression-style taps, where washer replacement is the most common fix. Now, some of you might be thinking, "Okay, great, but why can't I just ignore a little drip?" Well, that little drip adds up! A dripping tap can waste a surprising amount of water over time, leading to a higher water bill. Plus, the constant moisture can stain your sink or bath and even damage the tap itself. So, tackling that leak is not only good for your wallet but also for your home's overall maintenance. And honestly, there's a certain satisfaction in fixing things yourself, right? You get that "I'm a DIY superhero!" feeling. So, let's get those tools ready and learn how to banish that drip for good!

What You'll Need

Alright, before we get our hands dirty, let's gather our supplies. Having everything you need within reach will make the job smoother and faster. Think of it like prepping your ingredients before cooking – it just makes the whole process more enjoyable. First up, and this is crucial, you'll need a new tap washer. But not just any tap washer! You'll want to make sure you get the right size and type for your tap. The best way to do this is to actually remove the old washer first (we'll show you how soon) and take it with you to the hardware store. This way, you can directly compare it and ensure a perfect match. Different taps use different sized washers, so a visual comparison is key. Next on the list is a flathead screwdriver. This will be your trusty tool for disassembling the tap. You might also want to have a Phillips head screwdriver on hand, just in case your tap has any screws with that type of head. It's always better to be prepared! You'll also need an adjustable wrench or a set of open-end wrenches. These will be used to loosen and tighten the tap's components. An adjustable wrench is a great all-around tool, as it can be adjusted to fit various sizes of nuts and bolts. But if you have a set of open-end wrenches, that's even better, as they often provide a more secure grip. Now, this is super important: you need to turn off the water supply to the tap you're working on! Locate the isolation valves under your sink (they usually look like small taps or valves on the water pipes). Turn the valve for the tap you're fixing clockwise until it's fully closed. If you don't have isolation valves, you'll need to turn off the main water supply to your house. This is usually located near your water meter. Trust me, you don't want to skip this step – a face full of water is no fun! To make things easier and cleaner, grab an old towel or rag to place in the sink. This will protect the sink from scratches and also catch any stray drips of water. It also prevents small parts from disappearing down the drain – a major time-saver. Finally, a small container is handy for storing the screws and small parts you remove from the tap. This will help you keep everything organized and prevent you from losing anything. So, to recap, you'll need: a new tap washer, a flathead screwdriver, an adjustable wrench (or open-end wrenches), you need to turn off the water supply, an old towel, and a small container. Gather your supplies, and let's move on to the next step!

Step-by-Step Guide to Changing a Tap Washer

Okay, guys, with our tools and supplies ready, let's jump into the nitty-gritty of changing that tap washer. Don't worry; it's not as complicated as it might seem. Just follow these steps carefully, and you'll have that leak fixed in no time!

Step 1: Turn off the water supply

I know we mentioned this before, but it's so important that it's worth repeating. Turn off the water supply to the tap! Locate the isolation valve under the sink and turn it clockwise. If you don't have one, turn off the main water supply to your house. Once you've turned off the water, turn on the tap to relieve any remaining pressure in the pipes. This will prevent any unexpected gushes of water when you start disassembling the tap. Safety first, always!

Step 2: Remove the decorative cap

Most taps have a small decorative cap on the handle that covers the screw. This cap can usually be pried off with a small flathead screwdriver or even a fingernail. Be gentle so you don't scratch the tap finish. Once the cap is off, you'll see a screw underneath. This is the screw that holds the tap handle in place. You’ll want to take care removing this piece as you don’t want to damage it!

Step 3: Remove the tap handle

Using your screwdriver (either flathead or Phillips, depending on the screw), remove the screw holding the tap handle. Once the screw is out, you should be able to gently pull the handle off. If the handle is stuck, try wiggling it gently or tapping it lightly with the handle of your screwdriver. But don't force it, as you don't want to break anything. Place the screw and handle in your small container to keep them safe. Don't worry if this part takes a bit of effort; sometimes, these handles can get a little stuck over time. Patience is key!

Step 4: Remove the tap valve

Now you'll see the valve body, which is the part that houses the tap washer. Use your adjustable wrench (or open-end wrench) to loosen the large nut that holds the valve body in place. Turn the wrench counterclockwise to loosen the nut. Once the nut is loose, you should be able to unscrew the valve body by hand. Be careful as you unscrew it, as there might be some residual water in the valve. As you remove the valve body, you might notice some build-up or corrosion. This is normal, but it's a good idea to clean it off with a wire brush or a scouring pad before reassembling the tap. A clean valve body will ensure a better seal and help prevent future leaks.

Step 5: Remove the old tap washer

At the bottom of the valve body, you'll find the tap washer. It's usually held in place by a small nut or screw. Use your screwdriver to remove the nut or screw. Once the nut or screw is out, you should be able to remove the old washer. Take a good look at the old washer. Is it worn, cracked, or flattened? This is a sure sign that it needs replacing. As we mentioned earlier, it's a great idea to take the old washer with you to the hardware store to ensure you get the correct replacement. Remember, a perfectly matched washer is crucial for a leak-free fix. This is a great time to inspect the valve seat as well, which is the surface the washer presses against. If it's rough or corroded, it might prevent the new washer from sealing properly. You can use a valve seat reamer to smooth out the surface, but this is an optional step. If the seat looks relatively smooth, you can probably skip it.

Step 6: Install the new tap washer

Now for the satisfying part – putting in the new washer! Place the new tap washer in the same position as the old one. Secure it with the nut or screw you removed earlier. Make sure the washer is seated properly and that the nut or screw is tightened securely, but not overtightened. Overtightening can damage the washer or the valve body. Just snug is good enough. You want a firm hold, but not a death grip!

Step 7: Reassemble the tap

Now it's time to put everything back together. Screw the valve body back into the tap, tightening the nut with your adjustable wrench. Make sure it's snug, but again, don't overtighten it. Replace the tap handle and secure it with the screw. Then, snap the decorative cap back into place. Give everything a little wiggle to make sure it's all secure. We're almost there!

Step 8: Turn the water supply back on

Slowly turn the water supply back on, either at the isolation valve or at the main water supply. Watch the tap carefully for any leaks. If you see any leaks, turn the water off again and double-check that all the connections are tight. Sometimes, a slight adjustment is all it takes to stop a small leak. But if you're still seeing leaks after tightening everything, it's possible that the valve seat is damaged or that you need a different size washer.

Step 9: Test the tap

Turn the tap on and off a few times to make sure it's working smoothly. Check for any drips or leaks around the base of the tap and from the spout. If everything looks good, congratulations! You've successfully changed a tap washer and stopped that annoying drip. Give yourself a pat on the back – you've earned it!

Tips and Tricks for a Smooth Repair

Okay, guys, you've got the basic steps down, but here are a few extra tips and tricks to make the job even smoother and more successful. These little nuggets of wisdom can save you time, frustration, and maybe even a trip to the hardware store. First up, take photos as you disassemble the tap. This is a lifesaver, especially if you're new to DIY plumbing. Taking pictures at each step will give you a visual guide to refer back to when you're reassembling everything. It's like having a roadmap for your repair! Trust me, you'll thank yourself later. Another great tip is to wrap the threads of the valve body with Teflon tape before screwing it back into the tap. Teflon tape (also known as plumber's tape) creates a watertight seal and helps prevent leaks. Just wrap the tape around the threads a few times in the direction that you'll be screwing the valve body in. This is a cheap and easy way to add an extra layer of protection against leaks. If you're having trouble loosening a nut or screw, try using a penetrating oil lubricant. Spray a little lubricant on the stuck part and let it sit for a few minutes before trying to loosen it again. The lubricant will help break down any rust or corrosion that's causing the part to stick. WD-40 is a popular choice, but there are other penetrating oils available as well. Just be careful not to get any lubricant on the new tap washer, as it could degrade the rubber. Speaking of stubborn parts, sometimes the tap handle can be really stuck. If wiggling and tapping don't work, try using a handle puller. This is a special tool designed to remove stuck handles without damaging them. You can find handle pullers at most hardware stores. They're a worthwhile investment if you do a lot of DIY plumbing. And here's a crucial tip: don't overtighten anything! It's tempting to crank everything down as tight as you can, but this can actually damage the parts and cause leaks. Tighten nuts and screws until they're snug, but not so tight that you're straining. Remember, gentle but firm is the key. Finally, if you're unsure about any part of the process, don't hesitate to call a professional plumber. There's no shame in admitting that a job is beyond your skill level. In fact, it's better to call a pro than to risk damaging your plumbing or causing a flood. So, there you have it – some extra tips and tricks to help you change a tap washer like a pro. Remember, preparation is key, so take your time, gather your supplies, and don't be afraid to ask for help if you need it. You've got this!

When to Call a Plumber

Okay, guys, while changing a tap washer is a pretty straightforward DIY project, there are definitely times when it's best to call in the professionals. Knowing when to throw in the towel and reach for the phone can save you a lot of headaches (and potentially a lot of money) in the long run. So, let's talk about when it's plumber time. First and foremost, if you're not comfortable working with plumbing, it's always best to call a plumber. Plumbing can be tricky, and if you're not confident in your abilities, you could end up making the problem worse. Remember, there's no shame in admitting that a task is beyond your skill level. Safety and peace of mind are worth the cost of a plumber. Another clear sign that you need a plumber is if you've tried changing the tap washer and the leak persists. If you've followed all the steps carefully and the tap is still dripping, there's likely a more serious issue at play. It could be a problem with the valve seat, the tap body, or even the water pipes themselves. A plumber will have the expertise and tools to diagnose the problem and fix it properly. Similarly, if you encounter any difficulties while disassembling the tap, it's time to call a plumber. If you can't remove a handle, a nut, or any other part without excessive force, you risk damaging the tap or even injuring yourself. A plumber will have the techniques and tools to safely remove stubborn parts. Now, here's a situation where calling a plumber is essential: if you notice any signs of water damage, such as leaks, stains, or mold, it's crucial to call a plumber immediately. Water damage can quickly escalate and cause serious structural problems in your home. A plumber can identify the source of the leak and repair it before it causes further damage. Additionally, if you don't have isolation valves under your sink and you're not comfortable turning off the main water supply to your house, call a plumber. Turning off the main water supply can affect other fixtures in your home, and if you're not sure what you're doing, you could create more problems than you solve. A plumber can safely isolate the tap you're working on without disrupting the water supply to the rest of your house. And finally, if you're dealing with a complex plumbing issue that goes beyond a simple tap washer replacement, it's definitely time to call a plumber. This could include issues like burst pipes, frozen pipes, or problems with your water heater. These types of problems require the expertise of a licensed plumber. So, to recap, call a plumber if you're not comfortable with plumbing, if the leak persists after changing the washer, if you encounter difficulties disassembling the tap, if you notice any signs of water damage, if you don't have isolation valves, or if you're dealing with a complex plumbing issue. Remember, it's always better to be safe than sorry when it comes to plumbing. A good plumber will not only fix the problem but also give you peace of mind.
