Single Lever Kitchen Tap dripping

Usually your Kitchen Tap is dripping from either

  • The Spout – recommend replacing Cartridge
  • The Handle – recommend replacing Cartridge
  • Where the Spout meets the Base – recommend replacing the O Ring Kit

At the bottom of this Post is also some Troubleshooting guides that might solve your issue of Single Lever Tap is dripping and are useful to take note of when replacing any new Spare Part. 

To find your Spare Part by Brand:
Here is our Spare Tap Parts Section by Brand.  If you know the Brand of your Tap, then click on that Brand Name. Each Brand Section lists the Spare Tap Parts by Tap. You can see which Tap Picture resembles your own Tap, and click on that to take you to the Spare Tap Parts in store for that particular Tap.

Due to the high volume of Spare Parts we might have a part in store but not listed on the website. Please EMAIL us if we stock Spare Parts for your Tap if the specific part that you require is not listed.

Where you do not know the Brand?:
You can still establish which Cartridge you have / need by comparing your own to our Cartridges in store:
First you will need to remove your own Cartridge. Here is our Guide How to replace a cartridge in your Single Lever Kitchen Tap which will help you remove your own one.  You can then compare your own one to the list in this link here of the most common (popular) Single Lever Tap Replacement Cartridges (which lists by measurement and picture and also provides links to purchase).

O Ring Kits are not so easy, in which case we would recommend that you email us a picture of your own Tap together with what ever information you have to hand e.g. approximate age of Tap (when it was installed) and if there is any brand on your Sink as that might give a clue to the brand of your Tap. Email all details to


Please note that parts might be modified by the manufacturers over the years of a product being made. Therefore while we can guarantee that the parts we supply are as per the technical specifications sheets provided by the manufacturers, we can not always guarantee that a part will fit an older version of a Tap. All spare parts that do not fit can be returned for a refund but we do not refund associated postage costs.

What can affect the performance of a Cartridge, and also would have affected your original one, is if there is / was debris inside the Tap. That would have caused your original one to fail but it can also have permanently damaged the mechanism inside your Tap (see below) even though the Cartridge has been replaced.

Here are some trouble shooting measures that you can take .

Running Water: is most often caused by the seating washer (at the base of the Tap cartridge) from the original part having been left in the tap, this washer should ideally come out when removing the original cartridge however this is not always the case, there are also other parts of a tap cartridge that could be left in your tap (there is a danger that any new cartridge could be damaged by a part left behind when removing the old cartridge so always look inside the tap for any loose parts before inserting the new part).

Dripping: dripping can be caused by the aforementioned but more likely is the presence of some foreign matter between the metal seating in the base of the tap and the seating washer at the base of your new cartridge.

It is recommended that a shot of compressed air is blasted across the metal seating and the seating washer visually checked for foreign matter prior to installation.

Water Supply: After installation any problems will almost certainly have been caused by your water supply having (carried some very small foreign matter which has) scoured the discs, or the discs having moved position (usually caused by over tightening during installation (fairly unlikely) and/or over rotation of the tap when turning it on or off (quite likely).

You should remove the Cartridge again and check inside the body of the Tap for any debris etc. as recommended above and try again.

Also please note that sometimes if a Tap is left continuously drip or a Cartridge becomes stiffer and is left for a time before replacing, then it can cause irreparable damage to the Tap itself that no Cartridge can fix.

Please note that due to the high volume of Spare Tap Part queries that we receive, and the information that we will require e.g. Tap Pictures etc, ALL Spare Part queries are dealt with via email. We do not answer Spare Part queries via telephone. For any query EMAIL and our Team will contact you as soon as possible.

    My daughter has asked me to repair her swan-neck mixer tap (Lamona 4801) The tap leaks at the spout swivel but only when it is running. I suspect that the o-rings need replacement but I’m unsure how to remove the spout. Could you please advise on the dismantling procedure and which parts to order? Regards Mr Leonard Badger – mob: 07905 906 188

      Hi Leonard, feel free to email me a picture of your tap, but on the information I have, this spout has a locking nut at the that you have to loosen, and then you remove the spout by pulling upwards. Please read this blog How to remove Kitchen Tap Spout that tells you step by step how to do it. If your Tap4801 is dripping at the base, then you need this O Ring Kit here that is suitable for both Lamona Victorian Tap 4801 and 4802.

    Hi , sorry to bother you. I bought an “O” ring kit off you a few days ago Part 1239r , to fix a leaking Carron Phoenix Tap. I have replaced the o rings , but there is still a bit of a leak , from where the pipe/tap sits into the base. The job was easy to do , and everything was clean , I was wandering if you had any tips/advice on what might be causing the leak still. I sent a picture of the tap to Sarah , who might still have it , but I could send again if needed. I would be grateful , for any help.
    Many thanks.
    Anthony Mitchell.

      HI Anthony, as per our email to you we would advise you to check again that the o rings are sitting correctly in their grooves. Then make sure that you put back the spout in the correct position and tighten accordingly. When replacing O Rings you have to be careful that you don’t pinch them as if you damage them they won’t work. Also it is rare that you would need to replace the white O Ring as usually its only the black ones that require replacing.
