How To Fit A Lever Toilet Siphon | Dudley Turbo Duoflush 

This was by far the most professional well explained video I've seen. Thanks so much, life saver, mate. I'm gonna use your instructions to change my syphon around, give my toilet the lofe it needs. Straight to the point, no faffing around

Many thanks Dan, clear and concise instructions and a great recommendation to use the Dudley Turbo Syphon, works a treat.

Many thanks for a very helpful video! I've just bought one of the Dudley's to replace the flush over a Saniflo macerator toilet. The toilet itself was non working for ten years (the 'official' agent charged us £60 to replace the ball float which was nothing to do with the faulty toilet) but I finally managed to repair it with a new condensor and rubber gasket after watching yet another RU-vid video (not a pleasant job). I suspected the syphon was wearing out after the ten year holiday as the toilet pump starts up on its own a couple of times each day probably due to a slight leakage into the bowl triggering the pressure sensor, now the flush is only working on and off so its time to replace in the next day or two. This will be a great help as the toilet (fitted by social services for Dad) is incredibly tight to get at but once this is fitted - no more major jobs!

Well worth paying the extra for the excellent Dudley Turbo Syphon, as it is very straightforward for an amateur like myself to fit. This video just helps to give you more confidence to do things in the right order. Thank you Dan for the brilliant video, clearly explained.

Thank you, Dan. I had the same issue. Followed your steps and now the toilet is back in use. I wouldn't of had a clue if it wasn't for your video. Thank you so much

Thank you very much for a most helpful video showing me step-by-step, in detail, how it is done. Much appreciated!! I like to see how things work and this is both fun & informative.

Thanks so much for this video. Well explained and to the point. Just fitted my new siphon and fixed our toilet.

Thanks for this video. I discovered that I already had one of these syphons so all I had to do was buy and replace the diaphragm. So cheap and quick. No taking off the cistern which would’ve made the job impossible for me, as I am not very strong. Thank you.

Excellent, short, sharp useful, clear, easy too follow

Im going to fit one tomorrow ,following your instructions .

Great video mate, just changed mine by following your instructions. Very easy to follow 👍

Completely fabulous as others have said straight to the point and now we have a working loo again. Thank you so much.

Hi Been scanning the net for help on my toilet that won’t flush. Without doubt this was the best by far. Really clear great camera work. Well done keep them coming

very easy to follow makes it look simple, that new flusher looks well worth the money.. nice video ....

Great vid, helped me loads fixing our toilet, just wished RU-vid was out back in the day, would have saved me time and money✌️

Just used this to fit a new siphon - I'm bloody useless at DIY but this is so clear you can't go wrong. Thanks mate, keep up the good work! Btw I got one of those Dudley siphons - bloke in the plumbers' merchants also said it was worth spending a bit more to get one of these!

Glad your using dudley turbo 88s I’m not a plumber but when I’m older I want to be a plumber when I’m older but I have a shed of toilets that’s I’m still working on you should check it out !

Brilliant video showing how to put the syphon washer inside not outside as the instructions! Thanks

Used this today to help my mum. Top job, thanks!

Many thanks - this video has saved me getting a plumber. Quality description of how to replace cistern

Cheers fella , decent watch that was , easy to follow.

Thank you, just the information I needed, I'm off to get a close coupling kit and do a proper job.

Brilliant. Not only is it an identical toilet but you are also wearing the same T-shirt as me as well! - Ha! Anyway, thank you so much for this. Here we go!

Legend mate, replced this easy using your video. Much appreciated

Straight to the point , no life stories, great vid , cheers

Thanks, a handy video featuring the flush unit I was planning to buy for my first attempt at changing a siphon. One wrinkle: after disconnecting the cistern it refused to lift off the pan. Some googling revealed that it may be held down with silicone mastic and wiggling the cistern to and fro was required to free it. I installed the new flush without mastic, as recommended in the instructions supplied with the unit, and it's still watertight after several hours. (I also fitted new fibre washers on the inlet pipe.) How else to spend a wet May bank holiday?

Great job 👏

Dan, thank you so much. Your video was by far the best I found, so clearly explained. I fixed my non-flushing toilet within an hour, no problem. Cheers.

Great video, very informative!

very nice you do your job with only necessary talking, that is excellent

Im not only buying the dudley turbo, but I've subscribed to Dan's channel. This dude knows how to explain technical stuff in a very clear and concise manner that he should run an apprenticeship programme for youngsters. Thank you so much Dan. What happened to the Doughnut washer after all?

Great video, thanks

Brilliant vid mate 👍🏼

Great video, thanks. I used it yesterday when replacing our toilet siphon as it was not working properly. We actually got a Fluidmaster Ultra for lever operated as it was the only one at Wickes. I was fine fitting it but I’m stumped by how to set it or if I’ve set it correctly. You can adjust a couple of parts to do with water height and overflow height etc but I’m confused and not sure what to do despite reading the instructions I’m none the wiser. It seems to flush ok, however the handle is quite loose. When I tighten the nut inside the cistern it sticks, so have to leave it a little loose. Any tips on how you set the siphon I mentioned and how to sort the handle issue would be fantastic! Thanks again for the video

Brilliant video Dan, really helpful, thanks!

Just completed this. Your video is a good tutorial, but I experienced a couple of problems. First one was that my float arm caught on the new syphon side - so I had to heat bend it to an S shape. Second was a leak on the feed entry joint - I've had this before when reflacing a feed system - I managed to solve it using a rubber o ring washer instead of fibre washer - it sqeezed up tighter to make a better seal. These tasks are always straightforward till something goes wrong! Cheers again.

Absolutely brilliant video thank you so much - me and the husband managed to fix our loo and we are pretty proud of ourselves too! Great step-by-step instructions thank you

Yes! legend, doing that in the morning :-)

Great video Thankyou

Thank You. You safe my life 😉

Thks mate

Great advice, thank you. I was undecided about the close coupling kit but no convinced. I shall use a piece of hose pipe to syphon the water into a bucket. Unfortunately, I do not have a local stop valve so I shall turn off at the mains. I hope the job is as easy as you made it look. Cheers.

Such a help for us wannabe plumbers. Cheers.

Awesome!!...can't get a plumber because of the covid outbreak...so I'm going in!! 👩‍🔧 ...thanks for the help 😋

Good video. Just wanted to ask the plugs on the syphon i have no idea which one to remove or to keep on whether to keep the top one on or the bottom one on. If i just leave both on and fit the syphon in can i remove one of the plugs at a later time whilst water is already in the cisturn? Thanks in advance

Very good video. Just wish mine was as clean! Minging job!

Thanks for this video.. I'm going in! Need to buy some adjustable grips first though, what size would I be looking for for this job?

Really good video mate , no corners cut! Hate videos with loads of quick editing "do this do that bang job done" , you can't follow them!

Great video. My wife's flush system was leaking, so followed your instructions I changed it. Now my wife is like new and happy with the new tight diaphragm. But the problem is that she said that she is going to change my toilet cistern lever for the new and young one. I don't know what to do now... LOL))))

Just followed your instructions in my downstairs loo. Went perfectly, even for a ham-fisted novice like me! Lots of brownie points now for the rest of the bank holiday weekend. Many thanks 😀

Thanks

My old siphon has a 2" outlet, but these Dudley Turbo Duoflush 88 only seem to come with 1.5" outlets. Do you know if it would still work?

I agree with all the positive comments - a good video! In my cistern the float arm catches on a small blue tab that sticks out of the Turbo blue body section. I can't see what this blue tab does other than prevent the float arm from dropping fully down and make the refill slow. Can I just cut it off?

Great video. I am a complete plumbing novice but was able to change my knackered siphon which, as Dan suggested, had a knackered diaphragm. Only problem is now I have a slight drip from the vertical inlet. Any ideas how i can rectify this? Cheers.

Excellent video mate! Is that the same Dudley DuoFlush as I installed a couple of years ago? It's the most counterintuitive siphon you can imagine: to get a short, eco flush, you hold the handle down for ages, whereas for a normal, water-intensive flush, you just give the handle the usual short pull. As a result, no one ever uses the short flush, because it takes more effort, and you're never quite sure when you're supposed to let go of the handle! LOL. Madness.

How do we work oput what size of dudley siphon to use - is it about the height of the cistern or do they come in different hole sizes?

whats the water catcher thing called? my rod hook thing cracked so the hook is just loose now, idk if i should replace the whole siphon or just that.

my blue fill nozzle drips quite loudly, does this need replaced or is it a float issue? i will shortly be removing the loo for a tiler and think I will renew the internals while its off, was that dudley the adjustable model? saw lots of pin holes down the side just

Very helpful.

Good video - a slight different approach to the donut washer compared to other videos - placing it on the pan rather than the locking nut under the cistern. I guess the end result is the same?

Thank you xx

Screwfix sell the diaphragm membranes for Dudleys, simply pull the yellow pin out, remove flush hook, remove old plastic diaphragm and replace. Takes 3 mins. Easy.

Very informative, the thing is I have my cistern almost 7’ from the floor and about 18” from the ceiling so not much room to work with. Making things more awkward the cistern is a 40 + years old ‘Shires’ unit which contains asbestos everything other than the syphon works fine including the mains feed & overflow pipe. What do you suggest other than calling in an expensive hazmat plumbing team? BTW I live in a council house.

How do i make internal overflow work? Remove yellow peg?

The unit shown here has a TWO part fixing. 👀Some units have three parts (as one unit) 1. A large screw collar that secures the dome to the 2. main squarish unit PLUS 3. another screw collar that screws to the fixed down pipe within the cistern. Make sure you have the right one unit! ( Ideally remove, take to your supplier/retailer DIY et) 👀👍 Most are UNIVERSAL fixings BUT! ALWAYS make sure especially when ordering online etc

Did this method but it leaked. Replaced the washer with some silicone sealant. No leaks! Otherwise it’s a great syphon! Cheers

Can you tell me where the problem lies, when the flush handle won't return more than half way, after flushing. I have to lift it to the top position, before it will flush.--I lubricated all moving parts, Thanks.

Cheers Dan! Very clearly explained throughout.

Nice video I can't take my water bowl off the wall, previous fitter put silicone all around it and the screw's are rotten. Been trying to take it off for last few days, no luck yet.

Is there an internal overflow system (where you cant have pipe to the outside) and will water continue to flow after flushing?

Instructions weren't clear enough. Now I have a Italinox Prisma 16" Belt Conveyor Pizza Oven C/40 Natural Gas. With Free Stand. Thanks a lot.

Spot on. Thank you for making a middle-aged man's life easier and cheaper. Straightforward and easy to understand instruction.....now.... do you do bathroom fans....? :)

it's lucky the installer, did not use steel screws to attach the cistern to the wall, or it would have been a pain to remove rusted screws, a good plumber who has maintenance experience would use screws which do not rust ( stainless or brass ) if they care. and the thomas dudley turbo 88, has an internal overflow, great video, thanks.

Thank you Dan. One question. I live un México and we dont have does type of flush... if your wc dont flush that much and its not obstruct, we need to buy a brand New wc, not to replace de system.. when I was in africa I se this really old wc but the flushing system was hydrsulic and did like a pumping, so your waste could go with out a problem. the one that you are showing does something like that. Thank in advance

If you have trouble fitting a blank -just put a slightly undersized O ring over the washer then fit.

How do you know what size dudley to get

Where the blue plastic part is where the water runs out into the tank, the white plastic threaded screw that shuts off the valve for the water can you replace them individually? Been trying to source that particular part but can't find it on its own!? Cheers

Hi , do you know what the stroke of the 88 siphon is . i.e. how far does the lever lift the centre yellow plastic spindle?: Thanks

Thanks. That looks easy enough but I did think it was a smaller job to replace the Dudley siphon. I couldn't bear to put that filthy rusty old thing back on the wall once I knew it looked like that.

Is there any way to change the syphon without taking it off the wall?

Didn't need to purchase a new unit, just cut up some plastic bag and renewed the"flapper " seal. But thanks for the video.

👍👌 you'll be back to sort that out when the plate gives. 🤦‍♂️ some customers.

Skylo syphon is sitting to high in cistern. When I flush it pushes up the cistern lid. Tried to lower via twisting lower but still too high. Help.

OK, great vid BUT! It should be made clear that you do NOT have to remove the unit from the wall to replace the siphon unit!! 👀NOT do you have to empty the unit completely. It is more than likely that the siphon unit NOT the inlet valve or ballcock et will need replacing ! 😶If you have a heavy ceramic unit believe me the last thing you want to end up doing is stripping it off the wall !! I've just replaced our siphon unit and yes the overall cost is about £20 all in BUT as said here, it is NOT worth compromising with a cheap unit. !! 👍Lastly, stay safe!

Hi dan most plumbers i know always use sealent around the siphon washer and ptfe tape on the nuts to be absolutely leak proof would you recommend this.

Excellent video - the language simple and thorough. However the resemblance to Tommy Cooper "Just like That" cannot be avoided..! Apologies - a great job..!

not to be a ass or anything but why did you not turn the isolation valve all the way??

Great instruction video.....except for "go ahead" said too often

Very good thanks. Just one thing, only Americans “go ahead” before they do anything. I love our American friends, and I think they deserve their monopoly on that expression. You’re welco… (oops, sorry!)

I would never again buy these flush systems they only work for a short while before failing.
