The video was posted 12 years ago and I found it very useful in 2023, thank you - it was very informative.

Brilliant. It's a testament to the effort you put into your channel, that more than 8 years later, people like me are still finding your older videos really clear and useful. Thanks very much! 👍

Followed this tips in this video today. Got away with just replacing the piston in the syphon. Total cost £1.20. Sorted! Mine is not a close-coupled toilet, so didn't have to remove the cistern which made it easier, as mentioned in the video. A tip I picked up is that you can now buy syphons which are in two pieces which means you can repair or replace just the moving bits without disturbing the pipework or the cistern. Why they weren't all designed like this in the first place is a mystery.

I've had issues with the flush on my toilet for a while. got a plumber to come and take a look and of course it worked fine that day. After a few days of taking a few times to flush, it finally packed in altogether on the bank holiday weekend. This video was an absolute lifesaver for me. Without it I would have had to wait several days for a plumber and find someone to wait for them whilst I was at work. Having watched the video several times, I made a list f everything I might need, then went on the Bank holiday Monday to buy it all. Had a lot of difficulty getting the cistern off the wall because of rusted butterfly nuts and so had to cut them off. following the video though, everything else was fairly straightforward, even for someone like me who does as little DIY as possible. Great tip on the syphons that don't need removing in future to replace the membrane. Thank you for posting this.

This is such a great video, thank you! I've just changed the syphon in my toilet, followed your superb advice and completed the job with no problems or leaks. Awesome! You have a real talent in explaining and demonstrating using high quality video and sound which makes tackling plumbing jobs so much simpler and safer. Thanks again

Just want to say thank you so much for this video. Today I did my first Syphon repair many many thanks for your guidance in this video. Brilliantly done video.

Really good video, covering all the details. As a rookie I successfully followed it step by step.

Thank you for this thorough video!! I watched it this afternoon and tonight have accomplished the task. Couldn't have done it without your help! Thank you!

You made this video in 2011, but I just want to say thanks in 2019! It's been really helpful today.

Thanks for a very helpful video !! Was tiling the bathroom floor and decided to remove the toilet (I had ZERO plumbing experience) Your vids really got me out of a hole and even had me talking like i knew what i was doing :D

I watched this video a few days before replacing the syphon, the “ home maintenance technician “ that my niece pays an insurance premium for said it was a difficult job, the cistern would probably crack and a new cistern and replacement tiling would be required!, and wouldn’t touch it I bought a new syphon and close coupling kit for £15, the old wing nuts and bolts snapped off when I used an adjustable for leverage so I was fortunate because I don’t have a small grinder, after that everything was comparatively straight forward, many thanks for a very informative video

I stumbled across this video while watching home improvement videos. In the US our toilets use a flapper with a chain hooked to the flush handle. Those syphon toilets you guys have look way better than ours. The US now requires low flow toilets, and they clog very easy. My fill valve broke in my toilet, so I bought a kit and replaced everything. The kit's overflow tube was taller than my original so I just set the fill valve higher. Now the flush is more powerful and it hasn't clogged up since.

This worked great for me! I had got a few quotes from plumbers that were way too expensive; so found your video on KZfaq, and decided to do it myself and saved myself a small fortune in the meantime! Cheers fella! ;)

well explained thanks, very helpful. I was going to attempt this myself but having seen the possible problem areas I think I'll call in a plumber.

The very best video on here for this type of repair/replacement. Thank you for saving me a fortune having to call a plumber. I followed your instructions to the letter using a good quality syphon - and it’s perfect now. Thank you again👏🏻👏🏻👏🏻👏🏻👏🏻

I too have a Dudley Turbo, which I fitted years ago. For some months it has been misbehaving, and the whole flush unit swung up as it flushed. I planned to replace the whole thing, and watched this video to remind myself what I did last time - and right at the end, as you reassembled it, you said "that needs to clip in at the bottom first - EUREKA! 2 minutes with hands in cold water and problem fixed! Thanks 👌

Excellent - felt like a pro when I replaced mine, really useful. Thanks for posting this.

Thanks for the video , i'm feeling brave enough to tackle the toilet on my own!

about 6 months ago I was shocked to get a bill from a plumber for £450 (he also had to be called back 3 times as hadnt actually sorted the problem)! I was there when he did the work and I would say in total he was at the house for about 2 hours. He tried to pass the cost off on parts but the bits listed I could by for about £30. Fast forward 6 months and toilet stops flushing.....Im not getting a plumber this time I thought! With the help of this video I managed to do it all myself for a total cost of £22. So annoying as replacing the siphon was actually more involved then the jobs I paid the rip off plumber for! Thanks so much for these videos. Really great content

Thank you so much for taking the time to upload this video, I've just replaced a broken diaphragm with the one in this video. I followed the instructions as directed and I'm delighted to say everything went well. Anyone watching this should know that if I can do this diy job successfully, then anyone can. Just follow what this guys instructs. Many many thanks.

Imagine my surprise when I realised that - that toilet is EXACTLY the same as mine LOL . . . . . . But I must admit after seeing the reason you've gone for the more expensive flusher unit you've convinced me that's the one to buy this morning before I crack on !

You made this video in 2011 and it's a valid today (Christmas eve) as when it was made. 24/12/2016 and my toilet cistern breaks - I have a family what do I do!! Well I watched your video. I dropped down to screw fix, who had all the bits you showed - now I have a fixed toilet for Christmas day ---- THANK YOU :) Never would have done this if it was not for your video :)

Excellent video. 1. Clarity of explanation: A 2. Accounting for the unexpected: A 3. Dealing with problems: A 4. Comprehensive instructions:A I was all set for a long job on mine. But after watching this video I realised I had a 3 part, that just disconnects and lifts right out. Nice. Great video. P.S: My membrane was ripped. It is a sad fact that they don't make it easy just to replace the sheet of plastic, environmentally irresponsible.

A first class, well presented, no nonsense, accurate and straightforward video tutorial. Helped me every step of the way on a like for like replacement. And no "mate" this no "hey guys" that. No unnecessary awkward banter. One of the best I have seen. Thank you.

Very good, clear instructions, easy to follow. I now feel confident to fix my non flushing cistern. I see you have one dislike, I can only assume that must be from another plumber. You know, the type of plumber that likes to draw breath through his teeth before telling you it ain't going to be cheap. Well done, great video.

Fabulous !! I have just repaired the toilet whilst my husbands away on business as a surprise !!

I needed a new syphon for our toilet in our static caravan and after watching this video i was able to visit the local plumber and return with everything i needed and instal it with no problems what so ever, great video.

A very in depth and clear video that made it so easy to replace the syphon... And it saved me £70 to get it repaired... Thank you so much for posting this video.

Thanks so much, I'm 15 and my dad wanted me to fix ours, this video made it pretty simple

TheMxrrab Yes, the Dudley Turbo 88 has an internal overflow. (They call it the spill over level)

My toilet stopped flushing and your video helped me both identify the problem and fix it myself with a new one from Screwfix. I needed to change only the blue part because luckily I was replacing an old Dudley Turbo 88R syphon so was able to leave the column part in place. I am female and 70 years old. Your video was instructive and reassuring. Thank you!

me and my son just fitted a new dudley system after watching this video, i am not a DIY person at all and this was a great help. we followed your instructions and got it done. a big thankyou for the video, saved a fortune on plumber bills.

good informative video fella. ive actually learned something today:)

A great help, thanks for posting

Good Work Fella! Just done it myself for £15 including vat. Saving me calling out a plumber! Thank god for you tube and handymen all over!

Top man for putting this video up. I'd done three quarters of the job but got stuck on which way up to fit the doughnut washer before I found this video. Good advice telling people to buy a replacement close coupling kit as well. If I'd found this video before, I would have saved myself another trip to the diy store. My downstais toilet is now working after 6 months ! Thanks very much !

your a genious!! thanks man!!

Very clear vid, thanks for helping us all save money pal, all the best

Excellent instructions. Probably just about the most informative 20 minutes I've ever spent on KZfaq! Thanks for posting.

Changed our faulty syphon today after seeing your tutorial. Perfect instruction. I was that confident i even changed the bottom fed inlet after i stripped the thread!!!! Thanks for putting this up, very grateful.

I'm pretty proud of the young man, the lad did a bang up job...

This is how to make an instructional video ! Thanks !

I realise now it IS possible to remove rusted wingnuts and bolts without cracking the cistern. Two plumbers have doubted it could be done. I've never used an angle grinder before but tempted to buy (or borrow) a cordless one and repair my occasional leaking cistern. I made the mistake a number of years not using a new donut-washer when I replaced the flusher. Which later resulted in rusting bolts. Thank you so much for such a well presented video.

just wanted to say a massive thank you, id never even lifted the to off a cistern before but now thanks to you shes flushing like a champ

Just want to say thank you, it was very useful!

Thank you so much for that video! It told me almost everything I needed to know. I didn't know beforehand that I would need a new close-coupling kit. I certainly needed that! The membrane on the original siphon had indeed broken. I got a £20 replacement from Screwfix and installed that. Now I have dual flush (good for me, being on a water meter) and also an internal overflow (the external overflow is still there, of course, but it won't be causing harm to my building if something happens). The new one is, like yours, far easier to replace than the old type if there is a problem in the future.

I couldn’t leave KZfaq without complimenting your video. Very thorough and meticulous step by step instructions. I actually came here looking for guidance on how to change inlet flow system but ended up watching how to change syphon system and watched your video till the end as it was not only entertaining but educational too. Thanks for taking your time to make a such a great tutorial video. You now have another subscriber. Cheers!

Quite simply brilliant video. I'm useless diy er but managers this in 25 mins this morning. Now I need to do a second toilet. Thanks very much, saved a fortune I reckon.

How do you tell what the capacity of the cistern is, 7l or 9l When I visit my family in Australia, they have normal light switches and sockets in their bathrooms and I have not heard of any accidents, so you can grind away with a mains operated angle grinder until your hearts content in Aussie!! Thanks for the video, it was very well explained with attention to detail

Thank you for saving me the cost of a plumber ! I have now successfully fitted a Dudley 88 in place of the cheap piece of kit fitted by the builders 12 years ago. Frankly I'm surprised the diaphragm lasted that long, but I'm not surprised the builders didn't fit a descent syphon in the first place. Thanks for an excellent and very helpful step-by-step approach .....fortunately I didn't have to angle-grind the bolts off, but I did take your advice to fit a new coupling kit as well to be on the safe side. Thanks again.

I wanted to thank you for this video. Imagine how chuffed I was when I went to my toilet this morning and say that it had a serviceable syphon installed. All I had to do was undo a plastic nut and pull out the flush. The reason for my poor flush was a damaged plastic diapram. I just cut out a bit of plastic from a thick carrier bag, using the old diaphram as a template, reassembled it all and it works a bloody treat. Wouldn't have done it without the advice of this video so cheers. £80 saved.

Hiya mate, I'd like to thank you for this great video you have made. I have never looked under a toilet cistern until this video and for the first time ever I was able to take apart the whole toilet system to replace the syphon and get my toilet working again. Thanks buddy, full credit goes out to you!

Mate, you not only saved my life with this video, you saved me a few quid too. Result! Thanks!

superb video - even 11 years after you made this video it helped me have the confidence to do replace my own syphon with minimal fuss. you saved me a fortune for a plumber visit. all in all, £30 bucks to get a working toiley again. Well done !

I've been putting this syphon replacement, off, on our close coupled toilet for ages due to the thought of it being complicated and there's water involved! But after watching your video, it was a breeze! I did have to have 2 goes at it because I had a very slight leak on the first go but i put a little bit of silicone under the syphon seal second time round and no leaks! Thank you for taking the time to share your knowledge 👊

Cheers Mate. I have just successfully changed the syphon in my loo, and after a couple of attempts at getting the tightness correct underneath the syphon. All is working perfectly. Thanks Again. You saved me money. Total Cost was 19 euros, and an hour and 15 minutes of my time.

Thank you so much for making this video. I have just successfully replaced the syphon on my own close-coupled cistern by following your guidance. You’re a hero!

OMG!! I have just returned from B&Q with a new syphon and have taken the old one out and replaced it.!! also added a push button and removed the handle so is now a dual flush. I would not have dreamed of doing this until i saw your video, so i definitely owe you a beer, or have two and use my loo ... great

May 2017 and your 2011 video is still doing its magic. Its May bank holiday and i was down to B&Q and followed your instructions including getting the more expensive sustem that cuts down future work. Brilliant video! ... Thankfully, my wing nuts came off easily.

Many thanks for giving me the confidence to tackle this job with your down to earth, clear and detailed instructions! 👍😃

Probably the best DIY instruction video I've seen to date. Excellent, keep it up and thanks.

Coming up to Christmas 11 years on from your video and I've got exactly the same problem. 20 years worth of rust, so I took your suggestion of the angle grinder and it worked a treat. Thanks for this mate, you've saved my bacon and I owe you a pint! I very much doubt it, but if you ever need any help with something chemistry-related, drop me a line.

Thank you so much for putting 'How to replace a coupled toilet syphon Dudley Turbo' online! You have given lots of detail and the step by step instructions were brill .

Brilliant thanks. Just successfully done mine following your advice to the letter. My loo must be 30 plus years old. Old looks and works great now. Phew!

Same from me fella. Watched your video and changed the flush mechanism myself rather than paying a plumber! Probably saved £30! Ideal. Thanks.

Very useful video - saved me from calling out a plumber! A lot of useful tips you don't get with standard instructions or DiY books - eg how to get the water out of the cistern if the toilet won't flush at all, without getting water everywhere. Realised my problem was that the doughnut washer wasn't on properly (one set of instructions told you to put it in the pan rather than on the outlet from the siphon). Once I'd pushed it fully onto the outlet pipe, no problem.

Thanks fella. I am essentially useless at DIY and with this video I have just replaced the Siphon in about 45 mins - only took that long cos I kept coming back to your video to check stuff. Absolutely spot on. Cheers.

i live in the U.S. and watch your videos mainly for entertainment even though most of what you post will probably not help me much here but I have gotten a lot of great tips from you. I never thought just how different american toilets can be from U.K. toilets. Our toilets have not changed much in a long time, nearly all of the guts in american toilets are universal, only thing that could be different would be the size of the flapper, which is what releases all the water into the bowl, but even then there are only two sizes and its easy to tell them apart. There are a couple of different styles of toilets but most (as in about 90 percent) are the same, white porcelain, with a 2 or 3 inch flapper (3 inch being post 2005 and 2 being pre 2005) and a single fill valve. Great videos though!

The best and realistic. Most videos tend to deal with brand new fittings which most of us don't have. I especially liked the fact that he advised of unexpected errors in that after ten years you shouldn't expect things to undo easily. Thank you. Figured you saved me £150 or more.

The most comprehensive and helpful video I have seen on the channel.. 2024 and still relevant. Sign of a Great tradesman!

Watched this on Friday night, purchased a new siphon & coupling kiting Saturday, stripped and repaired our toilet. Brilliant video, easy to follow, perfectly explained. I feel like a DIY God now 😄

Absolutely brilliant instructional video. Watched this several times,bought the pieces I needed for replacement and did the job perfectly thanks to your help.10 out of 10 mate.

It was good to see a genuine repair job, complete with the problems of dealing with rusted nuts and showing the accumulated grime. It made a pleasant change from seeing people easily disassembling shiny, brand new kit. I'm certain that without your video, I would have taken much longer, spent a good deal more and ended up either injuring myself or breaking some porcelain. Cheers.

Hi there. Many thanks for taking the time and effort to make and share this video. I've managed to fix our toilet without a plumber and was well prepared for the task before I started. The builder of our house left us with a legacy of shoddy plumbing work and through learning how to put right the wrongs myself I've managed to save some money and gain new skills.

brilliant step by step guide, it gave me the confidence to have a go replacing my ancient syphon which was misbehaving for the past few months. some great tips in there and I got the whole job done in just over an hour (longest job was removing the fittings and fixtures which had been there for about 30 years), thank you so much for this as it has improved my health immensley (mainly cured earache from the wife!! LOL).

What a star. I've got a toilet exactly like that and I've had to change the diaphragm twice in the last eight years and it was a horrible job each time. That two-part syphon is a revelation and I'll be getting one. Thanks!

Thanks. I had done this job once before in another toilet and had to get a plumber in eventually as I couldn't t stop the inlet from leaking. This time I bought a Dudley Duo, on the advice of the helpful plumbers merchants (before viewing this clip) and managed to fit it perfectly this time with confidence after watching this very helpful demonstration. I even refitted the rusty close coupling kit I had removed as I hadn't bought one to replace it, though I did use LS-X jointing compound just to be on the safe side.

Ah oldie but goodie. You have saved me yet again. I was terrified when I found out I had to remove the back. But your guide as usually are great and easy to follow. Thank you so much. 🙌

Fantastic video, many thanks. Saved myself a few bob which is handy as I'm expecting the arrival of my first baby in 4 weeks time!

Excellent video. Perfectly explained. Amazing that this video is 12 years old and my brand new toilet is installed in exactly the same way. Funny how some things don’t change. Your instructions helped me a lot. Thanks again 👌😎

Uploaded 10years ago, still amazingly helpful. Thank you buddy.

What an absolutely brilliant video. Clear instructions, explainations and surprisingly great camera work from those tight spaces! 👍

This is an excellent step by step instructional video. Thank you so much. I have learnt a lot and managed to replace my siphon without incurring any outside labour costs. I have installed a 3 part siphon as advised, so the next diaphragm change will be a piece of cake. Thanks again. Mark.

Just completed the job following your video.Thanks.It really helped.

Guy, this video is top notch. I took our old toilet apart and replaced the syphon in no time at all.

Thanks a bundle ~ I have changed the flush Syphon and the intakes on several toilets in the past, but never a Coupled Toilet ~ just looking at the set up made me pause (for a long time ~ then I found your Video ~ Outstanding ~ even got hold of a "Dudley Duoflush (about £20 in 2013) Split Syphon" so that next time the diaphragm gives up I don't have to take everything apart ... I am now sitting here waiting to check for any leakage (15 min & no signs) Once again ~ Thank you big time

Thank you for this video. Without watching this I would have taken and replaced the cistern until infinity! Instead of just 5 times! I watched this between the 4th and 5th time and realised I didn't have a rubber seal between the cistern and metal plate. No more leaks. Thanks!

11 years later and this is the exact information needed. Thankyou. Guess which toilet system we have? Yes, the hardest one. Time to break out the tools.

Hiya pal! Toilet wouldn't flush properly for a few days now. I watched this video last night and today i've carried out the repair. The membrane had gone- got a replacement and then put it all back together without a problem. I didn't need a coupling kit and the syphon was ok to re-use! £7.20 + vat for membrane, silicone and silicone gun. Many thanks! Top Man! :-))

Excellent video - totally clear and easy to follow. I now know I need a new syphon and will get a plumber to fix it! Thanks so much.

Great video, really easy to understand. I feel confident enough to complete this task myself! Thanks.

Hiya mate, excellent video, well done! Had no experience taking apart a cistern and viewed this twice before buying the parts and tackling the job. Stupid loo was 20+ years old & had a "siphon bomb" system, so even with a new siphon it just filled the bowl and wouldn't flush, even after taking it apart 10 times! Gave up, bought a complete new toilet after finding out siphon bombs stopped being made 15 years ago! Couldn't have tackled it without you though, thank you very much!

Thanks for whoever did this film. Gave me the confidence to do it myself. Didn't go quite as smoothly as shown - but got there in the end.

Excellent video. Best part is showing likely problems and being prepared for the worst - especially the advice on having a replacement closed coupling bracket. Thank you.

I had to replace the syphon, nearly bought a full new one, however, after watching this video I realised I only needed the one part without dismantling from the wall. Absolutely great info and thanks for sharing. PERFECT!!

Excellent video: clear tuition and very good camera angles.

Clearest and most helpful DIY video I’ve ever found, seriously, brilliant. One trip to screwfix and I was sorted. Thanks for the heads up about the couple kit too. Absolute pooetry in motion 😉

Very detailed with simple easy to follow instructions. I watched it twice and replace with Dudley turbo height adjustable system from B&Q for £23.00, coupling kit was £3.97 and a new washer instead of using the old one which cost £2.04. Total cost was £29.01 exactly and 2 and half hours of time. I had to cut the bolts off from old one as well and good cleaning took time. Just to say thank you for the video and could not have done without it since I didn't have a clue about this before.

Absolutely cracking video. All the potential snags you mentioned showed up on mine toilet. Really really useful and so clear. The o-ring on my overflow pipe had gone too but only realised after refitting late on a Sunday. Thank you.

Amazing video tutorial... you sir are a star! Plumber wanted £120 to replace our syphon... I followed your video steps and done it myself without any problems (thank god).. Cannot thank you enough for your efforts in producing this video...
