How To Fix A Dripping Tap In Bathroom Sink

Need to replace a leaky sink or shower faucet? Here's an easy repair guide to get the job done inexpensively and a quick tip to quiet the noise from a dripping faucet until you can make that repair.

The Deafening Sound of a Leaky Faucet

You're laying in bed when you decide to kill the lights, turn off the TV and turn in for the night. It's not too long before you notice the "drip, drip, drip" noise coming from the bathroom. You try to ignore it..."drip, drip". You cover your head with the pillow but the sound just keeps getting louder and louder..."DRIP, DRIP". You can hardly hear yourself think and up you go to see what you can do to make it stop!

I know. It sounds a lot like "Tell-Tale Heart" but you have to admit, it can seem that way when the faucet starts to leak. Perhaps you're better at tuning things like this out than I am but for me, it was the shower fixture and trying to ignore it was nearly impossible.

Well, I have some good news. Fixing that pesky drip can be quite simple and even better, may only cost you a couple of dollars. Let me show you how.

Finding the Right Replacement Faucet Cartridge

The first thing you'll want to do is to find the proper replacement part for your leaking faucet. Knowing the model of faucet you have can often help to find a replacement before you start the repair but if you don't have that information, remove the problem part and take it with you to the store to match it up with a universal replacement part. In this example, the leaking bathroom sink problem will be a bad cartridge located in the faucet handle.

NOTE: Cartridges may be specific to the hot and cold sides of the faucet. Make sure you get the right one.

How to Repair a Leaky Faucet, Step by Step

Turn off the water supply to the sink. Usually, there will be a shut off under the sink but if not, locate the main valve in the water line and shut it down from there.
Next, remove the cap on the handle of the faucet. Some may vary a bit but here you can see it's quite easy to locate and remove.
Now that the cap is off, remove the screw that is holding the handle in place and lift the handle off the faucet.
Then, remove the beauty ring if you have one. If there is a hex top on the beauty ring, you should be fine to just loosen it with a wrench. If not, place a rag around the ring before wrenching on it to avoid damaging the finish.
Lastly, remove the cartridge. It should wiggle out fairly easily with your hand.
Replace the cartridge. Be sure that it is seated so that the handle turns off and on properly before putting it all back together again. Otherwise, your handle may turn to the wrong positions from where it was before. Many of these cartridges are finicky this way but simple to figure out.
Enjoy! You'll sleep like a baby without that annoying drip and it only took a couple of dollars and a few minutes of your time.

Let's move on to that shower. It's slightly different but just as simple with a couple minor, potential differences.

Photo Guide for Faucet Repairs

This is a quarter turn valve. When turned a quarter of a circle, the water is off/on. You may have a smaller chrome style of this under your sink that will work just as well.

Make sure you're using a quality Teflon tape for this job since the chances are you won't be wanting to disassemble your faucet anytime soon. I've been using this Everflow Teflon tape for years with very good results. It sticks and seals very well.

Replacing a Faucet Washer

Replacing a faucet washer is just as easy as the cartridge and even less expensive. Here, we will be repairing a leaky shower faucet but the method would be the same if your sink has this sort of washer as opposed to a cartridge as we've seen above.

NOTE: You want to be sure you buy the right size washer replacement. When in doubt, remove the old one and take it to the store with you to match it up with a new one.

How to Repair a Leaky Shower Faucet, Step by Step

Turn off the water supply to the shower. This may be in an access panel on the wall behind the shower or you may have to shut off the main line as shown above.
Remove the cap on the end of the handle.
Remove the screw holding the handle on. This again will likely be a Philips screw.
Now, remove the beauty ring if you have one to expose the valve stem. Again, be careful of your finish and use a rag to protect the piece.
Remove the valve stem. This stem should have a hex area for you to place your pliers (channel locks) and grab hold tightly.
Remove the screw that is holding the rubber washer onto the end of the valve and remove the old washer.
Put the new washer in place and secure it back down with the screw you just removed.
Apply Teflon tape to the threads that you will be screwing back into the fixture.
Put the faucet back together in the same way you'd removed it.

How to Stop the Noise of a Leaking Faucet

Okay so I'm aware this may not be something you're going to do right away but I do have a tip to offer to at least cure the noise that annoys you. Tie a string from the dripping faucet to the base where the water lands.

The water will now run quietly down the string to the basin and never will a "blip" be heard. This will also show you how rusty the water is since the string will begin to "brown" from the water. This may tell you that it's time to flush that water tank.

The Benefits of Fixing a Leaky Faucet

Aside from not having to listen to that "drip, drip, drip" all night long, there are other benefits from taking care of this problem.

Money - A leaking faucet does cost money. Depending on the severity of the leak, it may not be much but it will pay for those washers you bought. If it's bad, it could be noticeable in your water bill.
Water stains and deposits - This slow leak can increase the rate of which deposits build up on the filter in the faucet, thus blocking up the flow of water or consistency of the stream. It can also cause staining around the drain.
Mold growth - If there is a faucet leaking that isn't used regularly, mold will eventually begin to grow in the sink where the water is being splashed too. This light mist of water makes a damp surface where mold can begin to grow and once it establishes a foothold, it will grow quite rapidly from there and now we're talking about bad smells and potential health concerns.

Easy to Do Yourself

This is definitely one of those repairs you don't want to have to pay large sums of money to have done. With a couple of simple household tools and a few dollars for a replacement part, you can fix this problem easily and in just a few minutes. The repairs shown to the shower and faucet in this hub took a total of 20 minutes to do both. For even the less mechanically inclined, this is a repair that takes just minutes.

I'm having a heck of a time trying to get the stems out of my bathtub faucet, it's an American standard I'm pretty sure. Whoever put it in must have been very confident it would never have to be worked on bcoz they made the holes for the pipes to go through exactly big enough to fit the pipes through. I can't get any kind of a tool in to the hex nuts to remove the stems from either side. And I'm not sure what I can do to make room for a toil without wrecking the faucet. Do you have any advice? Thank you.

What if you didveverthing right and the faucet still drips?

We live out in the country and have a well, with plenty of hard water. Our faucets don't last too long out here but I'll save your info when I have to change out the parts on the tub.

I love the step-by-step photo procedures: it really makes this hub! Sound, practical and useful advice. Voted up!

@ All my HubScribers - Thank you. I'm glad these hubs are helpful. That is 100% my aim when I write these. Help people understand their homes so they can either repair it themselves or have a good understanding so they know what is they are being told by their service providers. Thank you all for stopping by and your very kind comments.

Cre8tor, your hubs are so useful. I am going to bookmark them all!!! What a talent for making something frustrating seem easy and doable. Your writing and illustrations almost make me want a dripping faucet so I can fix it.

Marcy Goodfleisch from Planet Earth on June 23, 2012:

I think your entire collection of hubs was designed to help me with my home maintenance! I have one of the double sinks in my master bath turned off due to a persistent drip, and I just replaced (courtesy of my son's skill at plumbing) the faucet in my kitchen. If we don't fix leaks right away, they cause considerable damage, and they also waste far more water than we realize. Voted up and up, and shared!

healthyjoe from Melbourne Australia on June 22, 2012:

Some articles are most informative, although I know how to change a cartridge (tap washer). Done many in my time, no i am not a plumber.

My new invention...."The Drip Trip". It's a string in a bag. I'll be rich!

Robie Benve from Ohio on June 22, 2012:

Great information! I have a leaky faucet, but since it does not drip gallons a day and can not be heard from the bedroom, I've let it be. Calling a plumber for something that small may not be worth the cost... but let me share this with my hubby and see if he's in the mood for some DIY. :)

alliemacb from Scotland on June 22, 2012:

This is such a useful hub. My dad taught me how to fix a dripping tap before I left home but I hadn't heard the string idea before - very handy.

Yvonne Spence from UK on June 22, 2012:

We had a tap (UK for faucet) that dripped for months and 2 plumbers said it couldn't be fixed - I can't remember why but something to do with its position in the middle of the bath. However, somehow my husband (who is not a plumber) managed to fix it. I have a feeling this hub would have come in handy for getting it fixed a lot sooner.

Nettlemere from Burnley, Lancashire, UK on June 22, 2012:

That string tip is really neat and definitely the way to go. I declare that all baths and sinks should have a piece of string hanging ready for emergency purposes!
