Replace cartridge + service single lever mixer tap

- Опубликовано: 2 июн 2024
- In this video tutorial I will demonstrate, step by step, how to dismantle a single level mixer tap and replace the cartridge and service the faucet.
Here is a summary of how I go about replacing the cartridge and servicing a single level mixer tap or faucet to fix a leak or to stop dripping. If the faucet starts to leak, either through one of its joints or continues to drip out of the spout after it has been turned off then most likely the cartridge inside the tap needs replacing. The cartridge resides inside the tap housing just under the tap’s handle. In chronological sequence these are the steps I suggest when changing the cartridge on a single level mixer faucet.
1. Buy the correct replacement cartridge - it is best to make sure when buying a new tap or faucet that it takes conventional, off the shelf generic cartridges. Mixer tap or faucet cartridge sizes are usually 25mm, 35 mm or 40mm diameter. Some upmarket types have specialised cartridges which are not always easily available. Some cases it may require replacing the whole tap, not too serious for a sink or a basin but disastrous for a faucet like shower or bath that is built into the wall.
2. Turn off water supply hot and cold and open the faucet to release pressure in pipes and check that it is off.
3. Take photos of tap before dismantling to avoid confusion when reassembling. Tip, hot is usually on the left.
4. Locate and remove cover to grub screw securing the handle and loosen grub screw usually, an Allan key of 2.5 mm will fit. Remove handle carefully
5. Remove finishing ring, if tight use a strap wrench to avoid scratching the chromium plating.
6. Remove brass cartridge retaining ring with a wrench, it may be necessary to hold faucet housing with strap wrench to avoid it turning with the brass screw.
7. Remove cartridge noting its orientation. This is a good time to talk about cause of leak. If it leaks through one of the tap joints then it could be leaking past the silicone-rubber gasket under the cartridge in which case a tweak on the brass nut holding the cartridge may help, if that doesn’t work then replace the cartridge. Leaking out of the spout is usually something failing inside the cartridge in which case again replace it. Now the only time you may consider opening the cartridge, to say hone the ceramic discs, is if you cannot obtain the specific cartridge for the faucet because opening and repairing the cartridge is highly unpredictable and should be avoided if at all possible. Which brings me back to my original point, when you buy a tap make sure it takes standard, off-the-shelf generic cartridges.
8. Check seat of the cartridge inside tap is clean, if it needs to be cleaned avoid scratching the brass seat, clean with a cloth only.
9. Apply a thin layer ‘O’ Ring grease to new cartridge’s silicone-rubber gasket
10. Insert new cartridge twisting left and right until it drops into place ensuring the 2 plastic locating lugs underneath the cartridge are in the lug holes in the base of the tap housing. The cartridge will now be ‘locked’ in the correct orientation and you should be unable to rotate it left or right.
11. Replace brass retaining ring and tighten moderately to compress the silicone gasket against the faucet housing base ensuring a good seal.
12. Replace Finishing ring with finger tightening only.
13. Replace handle but don’t tighten grub screw until you have, turned on the water and checked that faucet is operating correctly and that there are no leaks
14. Always also check and clean the filter-aerator on the end of the spout because if partially blocked it causes back pressure which may cause the cartridge to fail and be the original cause of the leak.

I have a very stubborn cartridge screw, what to do?
@@pitarnoartini7709 You could try a silicone or light penetrating oil spray into the thread. if that doesn't work then it is best to call a professional. good luck. let me know how it goes.
@@AnnErasmus grazie, its a specialized one so I had to call a pro
Thank You Sir for helping me save SGD200, I paid SGD6 for the cartridge instead of getting a plumber to install a new tap as recommended by the Hardware Shop. Really Greatful to You
You are most welcome 😊👍
This was so well explained I found replacing my cartridge a “piece of cake” I might even think about getting a job as a plumber.Thank you.
Thank you for the kind words, much appreciated. Good luck with your new career 😊
Excellent instruction on all types of mixing taps. Thank you!
You are most welcome, thanks for your feedback 😊👍
Brilliant.....I need to look at my mixer tap...it’s slightly leaking! Very informative.....thank you so much! 😀
Thank Mario, good luck with the job, hope it turns out well. As always your support is much appreciated 😊👍
Thanks for this really useful and easy to follow video ~ I managed to impress the family by changing a leaking cartridge.
Well done Jenny, pleased it worked out for you. Thanks for the feedback, much appreciated
Great video and a nice tip at the end about running off any dirty water.
Thanks for your feedback 👍😊
After watching this I realise I should be able to fix my own tap. Also great to see this advice from a fellow South African (can recognise the accent anywhere), so you know it's the same types of tools and parts we have locally, and call them the right names locally too. Definitely subscribed, thank you for this video!
Ja, I try to keep it simple 😊👍thanks for your feedback
@@AnnErasmus you're welcome. Einstein said anybody can make things complicated, but genius can make things simple
@@r0j0e agreed, I think it was Linnaeus who said words to the effect that if there are 2 explanations for a phenomenon the simplest one is more likely to be correct 😊👍
@AnnErasmus I think that's also Occum's Razor
Thought you were in South Africa as well... up to the point I heard Magpies in the background
Exactly the video I needed.
Pleased this was helpful, thanks for your feedback 😊👍
Very well narrated. Lots of useful tips.
My only minor nit (common to almost all these tap videos) is not to show folks who don't know, what a 'Grubb screw' looks like by itself.
👍😊
All the details are very well explained and there are also many helpful tips! Thanks a lot for the fantastic video!
Thanks for your feedback, much appreciated 👍😊
Thanks for this video. One extra piece of advice for anyone refitting a new cartridge - I could not get my cartridge to fit which was apparently due to the rubber ring seal around the cartridge that I had. Had to call my friendly plumber who put some silicone grease on this rubber ring and - hey presto job done!!!
Thanks for sharing this valuable piece of advice 👍😊
You are very good at explaining. Thanks!!!🙂
You are most welcome 👍😊
Thanks for all the tips.
You are most welcome 😊👍
Thanks for taking the time to prepare this video. Best explanation that I have found.
You are most welcome, thanks for your feedback
Excellent video ,thanks 😊
You are most welcome 😊👍
Thank you. Thank you. Thank you!!!!! Saved me $100. Tried the whole hose thing, nothing. Then moved on to the faucet head. The hot water side was completely clogged! Moved in our house in fall 2020. Had the issue since then and upset I took this long to try and resolve it. Lol much appreciated!
You are most welcome. Very well done sorting it out. Thanks for the comment
Thanks, just changed the cartridge and the seals on my kitchen mixer. Absolutely no issues thanks to your video. 👍

This is a really good description, even I could do it.
Thank you, you are welcome
Thanks for good tips.
No worries, you are most welcome 👍
Thanks for your video. I got as far as taking the red/blue button out, and it crumbled. I believe the tap is about 10 years old. I have had a look inside to find the grub screw - it looks very furry. Should I just get the tap replaced? It is in a shower, with no isolator, and in a difficult position. I have seen a replacement unit at Reece’s plumbing, so I know there should be a straight replacement.
Great Video
Many thanks for your feedback 👍😊
Very well explained.
You are most welcome, thanks for your feedback 👍😊
Hi thanks for your excellent presentation ! Can you recommend a tap handle puller ? Thanks
Thanks for the kind words. Sorry I don't know about tap handle pullers
@@AnnErasmus Thanks for your swift reply to my question .Cheers Eddie
Thank you, might just save me buying an expensive tap with a pop up waste.
You are most welcome 😊👍
Good info thanks. I wonder why they dont make a tap reseater for this size as whatever I do I can't stop it leaking which I guess is limescale. Tried cleaning but still happens.
You are welcome. I personally have not had good results with tap reseaters on conventional taps. CLR scale remover has worked for me in the past if it is a scale problem?? Good luck!👍😊
@@AnnErasmus I assume thats the issue. The original cartridge had a crack. Perhaps I haven't tightened it enough but didn't want to over do. Will take it apart and have a look again. Fun!
If you have not tightened enough it very often will leak out the tap housing as well as the spout. Good luck 👍😊
Any tips to remove that chrome ring? WD40 perhaps. My strap spanner keeps sliding off due to the curvature
Tricky one. All I can think of is to wrap some silicone tape around first to get a grip then try your strap wrench on top of that. Gentle heat (hair dryer/heat gun) may also help. Good luck.😊👍
Thanks for your video , lots of help there I have managed to change the original cartridge to an universal blue one like in video but now I get only warm water and not hot from the mixer why is that , any help will be appreciated
Not sure but it could be a leak at the silicone seal between hot and cold zones. Perhaps try tightening the brass ring a bit, if that doesn't help open it again and check for damage or grit on the washer or the taps seat? Hope this is of some help, good luck 👍
@@AnnErasmusyes I will open the tap and see , just incase there is some debris or grit near the washers or the cartridge is probably faulty as purchased from local DIY store
@@AnnErasmus thanks for your help once i find out what it is I will get back to you , cheers
@@nomercyforthewicked 👍
Could I change the other side of the rubber seal if it doesn't drops too much?
Maybe, try it 🤔
Just what I need how did you know
Thanks for the comment
After changing my tap filter it still leaks, should I just buy a new mixer tap?
Not sure what you mean by filter. Are you referring to the filter aerator at the end of the spout or the cartridge inside the tap housing under the handle?
I’ve switched the cartridge out and still have water running when off what’s next. Not dripping but a stream of water leaking
Probably time to call a plumber but here are a few suggestions, try taking the handle off the tap and operate the lever of the cartridge by hand, if it turns off like that then the tap handle and cartridge are not connecting properly . Also check the brass ring is fully tightened ant that there is no movement of the cartridge relative to the tap. Other possibilities are:- a faulty cartridge or a damaged or dirty seat of the tap. Hope this is of some help, good luck.
Hi, I have just recently installed one of these taps/cartridges and I have no hot water coming out. Could it be because of the cartridge?
First thing to check is that you have turned the hot water isolation valve back on. Sounds obvious but that happened to me once, that's why I mention it. Next I would check that the handle grub screw is engaging the lever of the cartridge correctly. That means the cartridge lever and tap handle should be in the 'off' position when you tighten the grub screw. If that doesn't help take out the cartridge and check that the hot and cold openings are working correctly as you move the lever (see video). The only other thing I can think of is that the cartridge is not lining up with the holes in the tap housing correctly, either due to the cartridge not being orientated correctly or not the right cartridge for the tap. I hope these suggestions will help, if not time to call in a professional, good luck 😊👍
@AnnMatt Erasmus hey thanks for the quick reply. Not sure where I read in the comment section but someone suggested that there might be an air bubble in the hot water line and to run the kitchen tap and wash room tap to heat the pipes up. I turned the main water off and ran the hot water for a while. Not sure exactly how I fixed it but we got hot water going through the shower now. Lucky cause my next step was ringing the plumber. Thanks again.
@@poobum1966 well done! Thanks for sharing 😊👍
When I tried to remove the cartridge from tap the 2 hot and cold flexi pipes were connected to it, so I couldn't remove the cartridge on its own
Sorry I can't help, I have never experienced that before 🤷♂️. Good luck, maybe time to call in a professional or contact the manufacturer?
The cartridge in my tap is secured by what looks like a clip with four prongs and I have no idea how to get it out.
Sorry I can't help, have never come across one of those?
I replaced 4000 cartridge and still drips slowly any sugestions?
First try tightening the cartridge down slightly (careful not to over tighten).if that does not help then remove cartridge and check the rubber seal for dents, scratches or tears. Also check the seat of the cartridge in the tap for damage or debris eg calcium scale build-up. If all looks good then lubricate rubber seal and reassemble a very slow leak will sometimes stop after few days. Occasionally one does get a faulty cartridge which will need replacement. I hope this is of some help, good luck😊👍
I tried to get cartridge for my kitchen mixer tap went round all the plumber merchants couldn't get one anywhere ended up getting a new tap
Sorry, very frustrating. That illustrates my point about about tap selection if you have the choice. Thanks for your feedback 😊👍
The tap was about 10 years old been in since the house was built
Is so cheap now. Made in china
Yes👍😊
I have a trouble by taking off the first screw because with my tap now with the plat screw (Not PHILLIP HEAD & ALLAN HEAD Screw) but already turned by the previous plumper (Repairer). So now it is very difficult to complete the first step. The work must be stopped right there. Please give me any advise . Thank you very much HENRY 0411 139 099.
This is a difficult situation. Best to call a professional who may have specialised tools to deal with it. All I can suggest is to spray with light oil or silicone then put the screwdriver in the stot and give it a very small tap before turning. But be careful not to damage the tap or plumbing connections. Good luck 😊👍
@@AnnErasmus Yes I had the same problem. Allen key just spun in the grub screw which appeared to be very tight.. Looks like I will have to cur the tap off.
