How to Fix a Leaking Tap in 5 Minutes

Is your kitchen or bathroom sink constantly dripping, wasting precious water and annoying everyone in the house? You don’t need to call a plumber—it’s surprisingly easy for DIYers with basic plumbing knowledge to fix a common tap issue. Whether you’re dealing with an old-fashioned compression style faucet or the more modern type of cartridge-based faucet, it is possible to repair most leaks without too much effort. We’ll take you through all the necessary steps, from assessing the problem and getting together all the required tools before you start on major repairs. Keep reading as we break down how to stop that leaky tap!

Key Takeaways

• A dripping tap can waste a lot of water, so fixing it promptly is a good idea.

• Before starting, turn off the water supply to avoid any flooding.

• Worn-out washers and O-rings are often the culprits behind leaks.

• Carefully reassemble the tap, ensuring all parts are snug but not overtightened.

• Always test the tap after repair to make sure the leak has stopped.

Assess The Dripping Tap

Right then, that dripping tap. It’s more than just a bit of background noise, isn't it? It’s a constant reminder of wasted water and, let's be honest, a bit of a nuisance. Before we get our hands dirty, we need to figure out what’s actually going on. Understanding the source of the drip is the first step to silencing it for good. It might seem obvious, but sometimes the problem isn't quite where you expect it to be.

Understanding The Leak Source

Most of the time, a dripping tap is down to a worn-out washer or a faulty valve seat. These are the bits inside that control the flow of water. When they get old or damaged, they can't create a proper seal, and voilà – you get that annoying drip, drip, drip. It’s usually pretty straightforward to pinpoint, but sometimes it can be a bit more complex.

Initial Inspection Of The Valve

Let's have a quick look at the tap itself. Is the drip coming from the spout, or is it leaking around the base of the handle? This can give us a clue. If it's dripping from the spout, it's likely a problem with the washer or the valve seat inside. If it's leaking around the handle, it might be an issue with the O-ring or the packing nut. We're not going to take anything apart just yet, just a good old visual check to get our bearings. Knowing where to start can save a lot of faff later on, and it helps you gather the right bits before you start. For instance, if you're dealing with a compression tap, you'll be looking at washers, but if it's a ceramic disc tap, the internal cartridge might be the culprit. It's worth having a look at how to install a wall-hung vanity unit to get a feel for how plumbing connections work, even if it's a different job, as it covers water supply basics connecting the waste and water supply.

A dripping tap can waste a surprising amount of water. If your tap drips just once every second, you could be looking at around four litres of water wasted every single day. That’s nearly enough to fill a bathtub over the course of a week!

Gather Your Essential Tools

Right then, before we get stuck into fixing that annoying drip, we need to make sure we've got everything we need. It’s a bit like getting ready for a big bake-off; you wouldn't start without your ingredients and utensils, would you? Having the correct tools makes the whole process much smoother and, honestly, a lot less frustrating. You don't want to be halfway through and realise you're missing a vital piece of kit.

Essential Tools For Tap Repair

To tackle most common tap drips, you'll want to have a few bits and bobs ready. These aren't anything too fancy, and most people have them lurking in a toolbox somewhere.

Here's a quick rundown of what you'll likely need:

• Adjustable Spanner: This is your go-to for gripping and turning nuts and bolts of various sizes. It's a real workhorse.

• Screwdrivers: You'll probably need both a flathead and a Phillips (cross-head) screwdriver. Sometimes, the screws holding the handle on can be a bit hidden.

• Pliers: A good pair of pliers can be handy for gripping smaller parts or stubborn components.

• Replacement Parts: Depending on what's causing the leak, you might need new washers or an O-ring. It's often a good idea to have a small assortment pack just in case.

• Allen Key: Some tap handles are secured with a small grub screw, and these often require an Allen key. You might need a few different sizes.

It's always a good idea to check your tap type beforehand. Some older taps, known as compression taps, have separate washers for hot and cold water, while newer ones might use a cartridge. Knowing this can help you grab the right replacement parts.

Protecting Your Tap's Finish

Now, we don't want to fix a drip only to end up with scratches all over our nice shiny tap, do we? That would be a bit counterproductive. To avoid marking the chrome or other finishes, it's a good idea to use a soft cloth or some masking tape around the parts you're working on, especially when using a spanner. This little bit of extra care can make a big difference to how your tap looks afterwards. You can find a good range of plumbing tools at your local hardware shop, or even online if you prefer to shop from your sofa. For example, if you're replacing a shower hose, having the right wrench is key to a good seal plumbing tools.

Safely Shutting Off Water

Right then, before we get stuck into fixing that drip, the absolute first thing we need to do is stop the water supply. It might sound obvious, but trust me, you don't want a sudden gush of water when you're trying to get to the bits inside the tap. It's a bit like trying to change a tyre with the car still rolling – messy and not very effective!

Locating Your Main Water Shutoff

Most homes have a main water shutoff valve, often called a stopcock. You'll usually find it where the main water pipe enters your house. This could be under the kitchen sink, in a basement, or even outside in a small box. Knowing where this is before you start any plumbing job is super important. If you can't find individual shutoff valves under the sink for the tap you're working on, this is the one you'll need to turn. It's usually a lever or a wheel that you turn clockwise to shut off the water. If you're unsure, a quick look at your home's plans or asking a neighbour who's done similar work might help. You can find more general advice on water shutoff valves.

Using Isolation Valves

Lots of modern sinks and basins have what are called isolation valves. These are smaller valves, usually found on the pipes directly connected to your tap, often tucked away underneath. They're really handy because they let you turn off the water to just that specific tap, without affecting the rest of the house. You'll typically see a small handle or a screw slot on them. Use a screwdriver or your fingers to turn these clockwise until they stop. It's a good idea to run the tap for a moment after turning these off to make sure no water is coming out. If your tap doesn't have these, or you can't find them, then it's back to the main stopcock.

Valve Type	Location
Main Stopcock	Near water meter or where pipe enters house
Isolation Valves	On pipes directly under the tap

Once the water is off, it's a good idea to open the tap you're about to fix. This lets any remaining water drain out and also confirms that you've successfully turned off the supply. Don't forget to pop a plug or a cloth into the sink drain at this stage – you really don't want any small parts disappearing down there! It's a simple step, but it saves a lot of hassle later on.

Removing The Tap Handle

Right then, the next step in banishing that drip is getting the tap handle off. This might sound a bit daunting, but honestly, it's usually pretty straightforward. You'll need to get to the inner workings to sort out the leak, and the handle is the main gateway. Different taps have their own little quirks, but the general idea is the same.

Accessing Internal Components

Once you've got the water safely off (don't forget that bit!), you'll want to find a way to lift or unscrew the handle. Sometimes, there's a decorative cap on top or front of the handle. You can usually pop this off gently with a flathead screwdriver. Underneath that, you'll likely find a screw holding the handle in place. This could be a standard crosshead screw or, on some modern taps, an Allen bolt. If you can't see a cap, have a look around the base of the handle or on the side. Some taps, like certain Monello designs, have a small grub screw hidden away on the side that keeps the handle firmly attached. You might need a small Allen key for this one. If you're struggling to get a handle off, a gentle tap upwards with a hammer, using a rag to protect the finish, can sometimes help loosen it. Just be careful not to force it too much.

Identifying Hidden Screws

So, you've turned off the water, and you're ready to tackle the handle. The trickiest part can be finding that screw. Many handles have a small cover, often a plastic cap, that hides the screw head. These caps are usually quite small and might be coloured red for hot or blue for cold, or just plain chrome. A thin flathead screwdriver is your best friend here for gently prying it off. If there's no cap, look for a small hole on the underside or back of the handle. This is often where a grub screw is located, and you'll need the right size Allen key to loosen it. For some older taps, the screw might be right on top of the handle, under a decorative cover. The key is to look closely around the entire handle assembly.

Here's a quick rundown of common screw locations:

• Top of the Handle: Often hidden under a decorative cap.

• Front of the Handle: Similar to the top, a cap might conceal the screw.

• Underside or Back: Look for a small hole where a grub screw might be.

• Side of the Handle: Especially common on lever-style taps, a grub screw can be tucked away here.

Once the screw is out, the handle should lift or pull off. If it feels stuck, give it a gentle wiggle. Avoid yanking it, as you don't want to damage the internal parts or the tap body itself. If it's really stubborn, you might need to consult your tap's manual or look up the specific model online to see if there are any unique removal steps. Finding the right replacement parts is much easier if you know your tap's make and model.

Diagnosing The Cause Of The Drip

Right then, so you've got that annoying drip, drip, drip going on. It’s not just a noise nuisance, you know; it can actually waste a surprising amount of water – we're talking litres a day! Before we get stuck into fixing it, we need to figure out why it's happening. Most of the time, it’s down to a few common culprits inside the tap itself.

Checking Washers And Seals

The most frequent reason for a leaky tap is a worn-out washer. Think of it like a little rubber seal at the bottom of the tap mechanism. Over time, with all that turning on and off, these washers can get stiff, cracked, or just plain worn down. When that happens, they can’t create a proper seal anymore, and water finds a way to sneak past, hence the drip. You might also find other small rubber seals in the tap that can degrade in a similar way.

Inspecting The O-Ring

Another common troublemaker is the O-ring. This is a small rubber ring that sits around the spindle of the tap. Its job is to stop water from leaking out around the handle area. If this O-ring gets damaged, perhaps from age or if it’s not seated correctly, you might notice a leak coming from the base of the tap handle, or sometimes it can contribute to the main spout drip.

Examining The Tap Seat

This one’s a bit less common but still worth checking. The tap seat is the bit inside the tap where the washer presses down to stop the water flow. Over time, especially if you have hard water, this metal seat can get a bit rough or corroded. If it’s not smooth, the new washer won’t be able to seal properly against it, and you’ll still get that drip. You can usually feel if it’s rough when you run your finger inside (carefully, of course!).

It’s always a good idea to have a look at these parts when the water is off. Sometimes, you might think it’s the washer, but it’s actually the tap seat that’s causing the problem. Getting the right replacement parts is key, so if you can, take the old bits with you to the shop. You can find replacement washers and O-rings at most local hardware stores.

Here’s a quick rundown of what to look for:

• Washers: Check for cracks, stiffness, or signs of wear. They should be pliable and smooth.

• O-Rings: Look for splits, tears, or if they seem stretched out of shape.

• Tap Seats: Feel for any roughness, nicks, or corrosion on the metal surface where the washer sits.

Replacing Worn Components

Right then, you've got the tap handle off and had a good look inside. Now it's time to swap out any bits that look a bit tired. This is usually where the problem lies, so let's get these parts sorted.

Replacing The Tap Washer

This is probably the most common culprit for a persistent drip. The washer, usually made of rubber, sits at the bottom of the valve stem and presses against the valve seat to stop the water flow. Over time, it can harden, crack, or get worn down.

1. Locate the old washer: It's typically found at the very base of the valve stem you removed. You might need a screwdriver or some pliers to gently pry it out.

2. Match the new washer: Take the old one with you to the hardware store to get an exact replacement. They come in various sizes and types, so getting the right fit is key.

3. Fit the new washer: Pop the new washer into place. It should sit snugly in its recess.

Installing A New Valve

Sometimes, it's not just the washer but the entire valve mechanism that's seen better days. If your tap has a more modern cartridge system, you'll be replacing that instead of a simple washer.

• Identify the valve type: Depending on your tap, this could be a ceramic disc cartridge or a different type of valve assembly.

• Remove the old valve: Once the handle and any retaining nuts are off, the valve should lift out. Note its orientation.

• Insert the new valve: Carefully place the new valve into the tap body, making sure it's aligned correctly. You might need to refer to the manufacturer's instructions for specific models, but many reputable brands provide long-term guarantees, so checking warranty details before purchase is advised.

Replacing The O-Ring On A Spout

If the drip isn't coming from the spout itself, but rather from around the base of the spout where it swivels, then the O-ring is likely the issue. This little rubber ring creates a seal between the spout and the tap body.

• Access the O-ring: You'll usually need to remove the spout itself. This might involve unscrewing a retaining nut or collar at the base of the spout.

• Remove and replace: Once the spout is off, you'll see the O-ring(s). Carefully slide the old one off and slide the new one on. It's a good idea to lubricate the new O-ring with a bit of plumber's grease to help it seat properly and prevent future wear.

Remember to lay out all the parts you remove in the order you take them off. This makes putting everything back together much, much easier. It’s like a little puzzle, but with a working tap as the prize!

It's worth noting that if your tap seat itself is damaged – you might feel rough edges or see corrosion inside where the washer sits – you might need a special tool to smooth it down or even replace the seat insert. But for most common drips, replacing the washer or the valve is usually the fix.

Reassembling Your Tap

Right then, you've done the tricky bit – replaced the worn-out washer, O-ring, or maybe even the whole valve. Now comes the satisfying part: putting it all back together. It’s really important to take your time here. Getting it wrong could mean another trip to the shops for parts, or worse, a bigger leak!

Careful Reassembly Of Parts

Remember how you laid out all the bits you took off? That’s your roadmap now. Start by fitting the new or cleaned components back into the tap body. If you replaced a ceramic disc valve, make sure it’s seated correctly – these can be a bit fiddly. For traditional taps, the washer and its screw usually go back in first. It’s a good idea to have a damp cloth handy to wipe away any stray bits of old sealant or grit that might have found their way in. This is also a good moment to check that the tap seat is smooth and free from any damage, as we discussed earlier. If you had to use a seat grinder, give it a quick wipe down.

Ensuring A Snug Fit

Now, start putting the handle and any decorative covers back on. Screw everything back together in the reverse order you took it apart. When you're tightening nuts or screws, don't go mad. A common mistake is to overtighten, which can damage the new parts or the tap itself. Think 'snug', not 'super-tight'. You want everything to feel secure, but not strained. If you had to remove a hexagonal nut at the base of the valve, use your adjustable spanner here, but remember to hold the tap body steady so you don't twist any pipework underneath. A little bit of gentle persuasion is usually all that's needed. If you're unsure about how tight to go, it's often better to be a little loose and then tighten it up after testing. We're aiming for a good seal, not to strip the threads. For peace of mind, you might want to check out guides on connecting water supply to understand thread sealing better.

Remember, patience is key. Rushing this stage can undo all your good work. If a part feels like it's forcing its way in, stop and check you've got it aligned correctly.

Here’s a quick checklist for reassembly:

• Replace the valve or cartridge first.

• Secure any retaining nuts or screws.

• Fit the handle or decorative cover.

• Tighten screws gently until snug.

• Wipe away any excess plumber's putty if used.

Once everything is back in place, you're ready for the final step: turning the water back on and seeing if your hard work has paid off. It’s a good idea to have your tools, especially the adjustable spanner, nearby just in case you need to make a tiny adjustment. You've got this!

Testing Your Repair

Right then, the moment of truth! You've gone through all the steps, replaced that worn-out washer or O-ring, and put everything back together. Now, we need to make sure it actually worked and that your tap isn't still playing the drum solo on your sink.

Turning the Water Supply Back On

First things first, let's get the water flowing again. Remember where you turned off the main water supply or the isolation valve? It's time to gently turn it back on. Do this slowly and steadily. You don't want to shock the system or cause any sudden pressure changes. Just a nice, gradual return of the water pressure is what we're after.

Checking for Any Remaining Leaks

With the water back on, keep a close eye on the tap. The goal is to see absolutely no drips coming from the spout. Also, have a good look around the base of the tap and where the handle meets the body. Sometimes, a leak can appear in a different spot if something wasn't tightened up properly during reassembly. Give the tap a good few minutes of just sitting there, then try turning it on and off a couple of times. This helps to settle everything in. If you're not seeing any drips and everything feels secure, congratulations! You've successfully fixed your dripping tap. It’s a satisfying feeling, isn't it? If, by chance, you still see a drip, don't panic. It might mean a component wasn't seated quite right, or perhaps another part is starting to wear out. You might need to revisit a step or two, or consider if a different part needs replacing. For instance, checking the tap seat is often the next logical step if washers alone don't solve the problem.

Here’s a quick checklist to confirm your success:

• No drips from the spout when the tap is off.

• No water seeping from around the handle or base.

• The tap operates smoothly when turned on and off.

If you've followed these steps and the drip has stopped, you've done a brilliant job. It's amazing what a bit of patience and the right approach can achieve around the house.

Once you've finished fixing your item, it's time to check if everything is working as it should. A quick test will give you peace of mind. If you need any help or want to see more tips, visit our website for expert advice.

Frequently Asked Questions

What are the main reasons a tap drips?

Most of the time, a dripping tap is caused by a worn-out washer or a faulty O-ring inside the tap. These small rubber parts can get old and lose their shape, meaning they don't create a good seal anymore, letting water sneak through.

Do I need special tools to fix a tap?

You won't need a whole toolbox! Usually, a simple adjustable spanner, a couple of screwdrivers (one flat-head and one Phillips), and maybe some pliers are all you need. It's also a good idea to have some replacement washers or an O-ring handy, just in case.

How do I know which part to replace?

After you take the tap apart, look closely at the rubber parts. If a washer looks flat, cracked, or worn down, it definitely needs replacing. For spout drips, check the rubber O-ring at the base of the spout – if it looks damaged, swap it out.

Can a dripping tap cause damage?

While a small drip might seem harmless, if left for too long, it can lead to water staining or even mould growth around your sink. It also wastes a lot of water, which isn't good for your bills or the environment!

What if I can't turn off the water under the sink?

If you can't find or use the small valves under the sink, you'll need to turn off the main water supply to your house. This is usually done using a stopcock, often found in a utility cupboard or near your water meter. Always double-check that the water is off before you start.

Is it okay to tighten everything really hard when I put it back together?

It's tempting to tighten everything as much as possible, but don't go overboard! Over-tightening can actually damage the new parts or the tap itself, leading to new leaks. Just make sure everything is snug and secure, not forced.
