Not only does that nagging dripping sound have the potential to irritate you, but it also presents three significant problems: higher bills, wasted water and an increased risk of developing catastrophic leaks and water damage. Failing to fix a leaky tap is like throwing money down the drain. Every extra unnecessary drop drives your water bills up higher and higher, with the potential to add anywhere from £20 to £200 or more to your annual bill. If the cost doesn’t give you pause, maybe the prospect of ending up with water damage or a major plumbing problem that costs thousands of dollars to repair in other areas of your home may motivate you to take action to perform a DIY tap replacement or hire a plumber.
Whatever prompts you to fix the leak, it’s crucial to get to the bottom of the problem and correct it. Read on to learn more about some of the most common causes of household leaks, along with the steps you need to take to fix one on your own or determine if tap repairs or replacement from a pro are necessary.
Unfortunately, taps don’t stay in working order forever. These mechanical devices are made of many different parts, all of which can become worn out after years of usage. Age, use and deterioration are among the chief causes of leaks. Some causes require a simple fix, while others pose a more complicated problem. Whether your leaking tap is in the bathroom, kitchen, or outside, common causes of tap leaks include:
In rare instances, broken fittings or pipes can cause a leaky tap by affecting your sink’s water pressure. If you’ve checked all of the other areas and still have a leak, it’s a smart idea to hire a plumber to inspect the pipes. Take a look at some of the common repairs associated with the sinks in different rooms of your home to better anticipate the type of tap repairs that may be necessary.
Without getting to the bottom of the leak’s cause, you run the risk of having an all-out blowout or overflow, which can leave entire rooms soaking wet. That water wreaks havoc on woodwork and floors while leaving surfaces vulnerable to bacteria, mold and mildew growth.

Bathroom sink taps come in a variety of styles, from ball-type taps to compression taps, which commonly leak because they need new seat washers or O-rings. To fix these taps, remove the decorative cap, unscrew the handle and unscrew the packing nut. Remove the old seat washer and replace it with a new one. Remove the stem from the packing nut and install a new O-ring before putting the tap back together.

Many kitchen sinks use ball-type taps, which contain a number of parts. This makes it difficult to identify where the leak is coming from, so you might be better off buying a replacement kit and installing all new parts. If you decide to fix the leak rather than replace the tap , follow these basic steps:
Don’t ignore that leak for too long. Even if you’re just a casual DIYer, this is a doable project for you because it requires only some relatively basic plumbing skills. Before you start gathering your tools, take a good look at the leaky tap to see where the leak is coming from. This should give you a pretty good idea of what part needs repair or replacement. For example, if the tap is leaking from the spout, the valve seat is probably the problem. If it’s leaking near the handle, it could be because of a packing nut that needs adjusting.
Average Time for This Project: One Hour
Step One: Turn Off the Water
For seasoned plumbing pros, this may seem like an obvious first step, but if this is your first time working on your plumbing, you might not realize the importance of turning the water water supply off, either from the knobs under the sink or the main line to the house. If you skip this step, you risk enjoying a geyser of water shooting from your fixture.
Step Two: Prepare Your Tools and the Tap
Taking a few minutes to prep your space makes this project run much more smoothly by keeping everything you need close at hand. Wrap the jaws of your wrench with duct tape to avoid scratching your fixture while you’re working. With the water supply turned off, turn the tap on to relieve any accumulated water pressure and to verify that the supply is off. Close the sink drain and cover it with a rag to avoid losing any small tap parts while you work.
Step Three: Remove the Tap Handle/Handles
Remove decorative handle knobs by prying them off the handle using a flat-head screwdriver. You’ll see a screw under each knob that secures the handle to the main body of the tap. Unscrew each of the screws and remove the handles. If the screws or decorative parts are difficult to remove, use WD-40 to help loosen things up.
TIP: As you start removing parts, take pictures to help you remember how to put them back together. Alternatively, lay them out in a row in the order in which you removed them.
Step Four: Inspect the Packing Nut
Start by loosening the packing nut with a wrench. Once the packing nut is loose, you should be able to see the stem. Remove the stem by twisting or popping it off the valve. Inspect all the parts for signs of damage or corrosion.
Step Five: Inspect the O-Ring and Washer
If the packing nut and stem are in good shape, proceed to inspecting the washer and O-ring located inside the tap’s valve seat.
Step Six: Clean the Valve
Look at the interior of the valve to see if there are any mineral deposits or gaskets that look like they’ve deteriorated. Loosen the mineral deposits by soaking the affected parts in vinegar and using a nylon scrubbing pad to clean the surfaces. Clean out any clogged holes in the body of the tap with a pen knife before flushing any debris by holding a rag over the tap and opening the water supply shutoff slightly.
Step Seven: Reassemble the Tap
Reassemble the tap in order of how you removed everything (O-ring and washer, stem, packing nut, screw and handle). If you’re unsure of the exact size you need for your replacement parts, take the old washer and O-ring to your local home improvement store for an exact fit, which is necessary to avoid leaks.
Step Eight: Test the Tap for Leaks
Once you reassemble the tap, turn the water supply back on. Turn the tap on slowly to test it. If you still have a leaky tap , it may be time to either call a professional or buy a new one.
If you’ve checked all the usual offenders listed above and you still have a leaky tap, you might be better off installing a new tap instead of pursuing professional repairs. This is particularly true if you’re working with an older tap . These fixtures often don’t last much longer than 10 years. Buying a new tap also has the added benefit of giving your sink an updated look. When you’re shopping for a replacement, measure the existing one and not how many holes are in the sink for the tap (one, two or three). Also note whether the holes are widespread or centerset so that you choose a tap that best fits your sink. Other situations in which replacing the tap might be the most time- and cost-effective option include:
If you’ve exhausted your personal plumbing abilities and still have a leak, or if you’re not comfortable approaching this as a DIY project, hire a plumber. Getting a professional in on this job provides peace of mind. Additionally, a trained professional can handle some of the bigger causes of problems, such as broken or cracked pipes, to fix the leaky tap and the underlying issue. Across the United Kingdom, the cost of hiring a plumber averages £212. Plumbers may charge by the job or by the hour. Average hourly costs range from £40 to £100, although calling a plumber for an emergency or off-hour project typically costs more.
When you’re hiring a plumber:
Fixing a leaky tap can be a fast, easy project, depending on the cause of the leak and the condition of your tap. Don’t let little leaks create huge floods. Whether you opt to work on this as a DIY project or you want to hire a professional, the faster you stop the dripping, the better. Think about all the money and precious resources.
