Whether it’s the cause of water pooling under your sink, or the annoying dripping sound that keeps you up at night, a leaky tap is a nuisance that could turn into a full-blown problem if not addressed properly.

Fortunately, putting a stop to a leaky tap can be surprisingly inexpensive and simple.

To fix a leaky tap, you’ll need some of the following tools to get the job done right:


  • Adjustable wrench; C wrench
  • Phillips and/or flat-head screwdriver
  • Penetrating oil, such as WD-40 or CRC
  • Replacement washers and O-rings

Remember: If the problem persists it may be best to contact your plumber.

If the problem persists it may be best to contact your plumber. Our team offers same-day and emergency services. If you’re feeling stuck we’re here to help. Give us a call!

Step One:

Before you go touching the leaking tap with anything, make sure you turn your water supply off. Either at the supply taps under the sink, or at the mains tap (turning= the mains off means your whole house will not have water during the repair of your tap). Don’t forget to all make sure the leaking tap is shut off as well.

Step Two:

A handy tip before proceeding is to plug the drain in the sink, this helps to avoid losing any small nuts, bolts or components down the drain. Remove any decorative temperature signage on the taps using a flat head screwdriver to reveal a screw or bolt underneath that holds the tap on. Gently remove this screw and remove the tap handle and tap itself. If it’s difficult to remove, some penetrating oil may help to loosen its grip.

Step Three:

Below the tap you will find a packing nut. This is where your wrench comes into play and you can feel like a plumber! Loosen the packing nut and below you will find the stem, this sits on top of the O-ring and the seat washer. Remove the stem and inspect for damage or wear, depending on your type of tap it may simply pop out or may need to be twisted out.

Step Four:

If the stem is intact, The O-ring and seat washer are the often the cause of a leaking tap, so remove them and inspect both for damage or wear. If need be replace the washer or O-ring. Its crucial that they are an exact fit. Check any other rubber seals or components that seem to be damaged.

Step Five:

Finally, carefully reassemble the system in the reverse way you took it apart (order of washer/O-ring, stem, packing nut, tap, handles, screw and cap), gently turn your water supply on and test for any leaks. And you should have a good as new tap!
