- AS ALWAYS, a QUALITY 'how it works' video. I cut an auto-syphon in half and fitted a plastic cover. Now we can see inside, and watch it in action.
Also I explain with an animation so that ANYONE can understand it!

THE MRMATTANDMRCHAY CHANNEL, established 2008:
I'm passionate about uploading quality and interesting videos for YOU, my audience.
What is my channel about? "Old lift machinery made interesting", old air-raid sirens, prehistoric alarm equipment. If "I" don't find it interesting ...then IT DOESN'T GET UPLOADED!
I always spend a lot of time editing my videos with animations, video in-sync with music and voice overs to make them this way.
My moto - "Quality NOT Quantity" - spending a month editing a video is not a rarity!
But without you, I'm nothing here. Thank you so much for watching.
...mrmattandmrchay is me (Matt) and my son Chay.
THANK YOU very much for watching :)
What a fantastic and complex video to make. Its operation is nothing like I imagined it would be. Basically a triggerable air lock.
Thanks Clive, I was very thankful to get the video finished in the end! I must have flushed this unit 100 times or more to get the best footage for the video! (plenty of water for the flowers below it!). It was very difficult to see how it worked, without cutting it in half and filming it in operation.
@@mrmattandmrchay I wonder if the use of copper for the final trigger pipe is to reduce the risk of a plastic one fouling up with slime, resulting in overflowing. Copper has antifungal properties.
@@bigclivedotcom That was my idea too
Came here from bigclivedotcom's video on the same unit - thanks for solving the mystery! What a fascinating device.
Steve Mould made one of these, and he directed us to watch your video as well :)
What a fantastic video and animation. Thankyou for all the work behind this, top class!
Glad you enjoyed it and thank you for the nice comment!
Excellent video! Steve Mould sent me and it did not disappoint
Here from
steve Moulds channel too. This type of content is awesome to me. I love learning how things work. I can’t wait to check out what other videos you have.!
Thanks very much for visiting! My channel is mainly about old lift technology, but I do go to a lot of effort to make them interesting, such as animations, timing music to the video content, etc. Hope you find something you like! :)
Many thanks for going through the trouble of showing us the works and cutting the syphon open for this demo.
I just had to! It was the only way to see exactly how it worked, very little infomation available on the internet about it, if any! Thanks for the comment
Respect to you sir, you are a clever fellow to work this out. I'm one of many people who have disassembled these things and failed to understand its secrets.
It did take a lot of time to plan then prepare the scenes! In the end I got a little tired of looking at the same bits and pieces. What you see here is the finished result, but I recorded literally hours of footage - better to have too much footage than not enough...! Thanks for the comment and compliment :)
@@mrmattandmrchay Sure, I know, 1 minute of good TH-cam material is at least 10x that in preparation.
@@mrmattandmrchay But that tank with the black floating things still gives me the creeps. I'm done with toilets for a good while thanks!
really fascinating!!! never even thought about how urinals flushed etc. now i know!
Perhaps, not something that you NEEDED to know lol!!
Well made video and hard work put into it... well done mate... great animation
This is brilliant , who ever thought this up is a genius .
wonder how many prototypes before they perfected it? Nowadays you could probably quite easily do this on a 3D printer!
Came from Steve Mould's video, glad he linked you! Dropped a sub.
Thank you for the info and for the sub. I've left Steve a message saying thank you!
Excellent demonstration. Thanks.
Absolutely brilliant scholarship and detective work-bravo! My pond has a bell siphon to send water over the earthen dam and keep the pond from overflowing in a way that would erode the dam. But since rainstorms don’t trickle like those old toilets, there’s no need for additional siphon stages, just one.
If I ever notice the need, I’ll cobble together a multistage gizmo now that you’ve explained it!
Very clever man. Congratulations
I can't tell what's more fascinating, the ingenuity that went into making a timed water valve with no moving parts or the ingenuity that went into your reverse engineering and documenting the whole thing. Either way, great video!
Massive compliment... thank you! 😀
Was searching for this kind of siphons for a long time! Did not understand fully how they work. Had some bad experiences with simple bell siphons as they depend a lot on water flow and pipe dimensions to work correctly. But this is a fantastic concept!!!! thanks for this video!
I'm so fascinated at the differences between UK and US water tanks. Thanks for the video, Matt!
Crikey! A lot of effort has been put in to creating this device, even though it just flushes water! Excellent video once again Matt!
...this is the mrmattandmrchay channel - quality not quantity.
Brilliant animation, really enjoyed this video
Thanks Petertronic, glad you enjoyed it! :)
These auto flush urinals go back a long was .I used to climb up the urinal to look inside when I was 6 so this is late 1950s.
I remember all the evil looking green slime.
I wonder when they were designed and by whom?
Surprisingly complex and clever solution - a cascade effect to trigger the full flush
What a great video all knowledge fully absorbed
What a great "how it works" video. Well done.
I went to buy some of these for my aquaponics (in Australia) and was shocked to find the prices here rather prohibitive... The standard "Bell Syphon" most aquaponics use is only good for small drains while this addresses that problem and would allow for any size downpipe.
If you are ever looking for a video idea... how about how to DIY one of these...
Again, great job on the video. I'm looking forward to seeing some others that you made.
i think the old one with the black limestone formation was a porcline basic syphon without all those cool parts. those are extremely rare where its part of the tank and can't be removed. basic bell syphons has been getting upgrades but the basic ones are still avalible and some are all clear where you can severything inside on esty. i don't think they make porcline ones anymore. did you know you could get a wine glass with a glass bell syphon inside? its made after the historic greedy cup. the first bell syphons were made long ago into ceramic cups called a Pythagorean cup. they would fill them with wine themselves and will be punished with no wine if they taken too much. clever idea no moving parts!
That was great. Thank you for making it!
And thanks for watching Jono! :)
For a person who doesn't like water tanks he does get into some detail
I think you'd call this "fear becoming a fascination", such as my interest with lifts - I was once petrified of them as a kid.
It’s basically gravity and water pressure at work. It reminds me of the high school physics examples with the communicating vessels. It’s quite a clever design. I wonder what would happen if the diameter of the small tube is enlarged. I think the small diameter is key in the pressure balance.
Once the diameter reaches 8mm or more, there's a chance that the upcoming air (from the "downpipe") passes the falling water, stopping the waterflow. Smaller diameters will fill completely with water.
The 8mm hole is an industry standard in windows & door drainage. If we go smaller, water will just remain on top.
Pretty interesting this video thought... Great job, mate!
subscribed, top notch video this. i'm going to watch it again.
Thank very much for the compliment and thanks for subscribing Owain :)
What a great demo! 😀👍
cool! Glad you liked it :)
i did not need to know then until I watched this video.... then it was obvious that i did lol it was fascinating !
Very useful. Thank you.
Glad it was helpful!
Great video. Would be also cool if you added dye to the water
Thanks for your comment and suggestion. I was actually going to do what you suggested but then decided against it, because I thought it might generally cloud up the whole area. It might have worked, but instead I put my video light on top of the capsule which seemed to help.
Broadmoor sirens were my favorite
We have many of these auto syphons in urinal cisterns in New Zealand, which is very common in NZ washrooms.
I have a question about this: why do some long urinals make a squeaking sound when they flush?
I know exactly the noise you mean. When there is no water coming down the pipes, there is air. When water rushes down the pipes, all the air has to escape, and can only escape through the small pin-holes where the water goes through. So you'll get water as well as air squeezing through those holes. The squeeking noise is the air escaping out of the tubes with the water.
Oh the water elevator part two.
What a brilliant device, easy enough to make out of plastic these days, but the original ones were rubber and cast iron.
Making a water syphon out of cast iron is probably not a good idea. It will quickly rust.
@@simontay4851, what do you think the old cistern tanks and sewer pipes were made of?
How about this one... th-cam.com/video/RlplkCASiE8/w-d-xo.html I remember my nan had one which leaked at some point and was replaced.
@@mrmattandmrchay, congratulations not only watching that Matt, but actually seeking it out in the first place, they really did make a whole lot of monsters under thee bed type noises.
what happens when you fill the tank half way and seal the top of the tank with the hose still going inside?
Where do I find this in the US?
I believe this is mainly used in the UK. These are all from the UK
1:12 im worried about the water, that green stuff its no good
here's something you should do for more views and subscribers. (i already subscribed) ever see those pressure vessels for toilets? there's not 1 video on TH-cam to show how it works! you litterally make the best videos. be careful with those because pressure vessels can explode. what's the mechanism behind it and how does it know when to stop adding pressure? the water psi is only 35. where does all that force come from and why does some air come out too during the flush? its obviously a sealed unit since the toilet tank is always dry so where does the air come from?
Why you didunt be used colored water ¿¿¿¿¿¿
Another interesting device ive seen before in public toilet is called a cistermisser. Could you do a how it works video about
The Cistermiser Hydraulic Valve is installed on the supply pipe to the urinal cistern. The valve is activated by short-term pressure drops created by use of taps or WCs on the same supply.
@@simontay4851 Wow, I never knew that - I thought it was a battery operated PIR connected to a value which fills the tank when the room is occupied (or just after), such as the PIR in the video.
This is still overly complicated compared to one that I have seen in our school washroom in the sixties! All it had was an inverted U shaped copper three quarter inch pipe with one end about a quarter inch from the bottom of the tank! The other end was of course the drop pipe to the urinal. As,all coil of pipe was brazed into the inverted U pipe at the top and the other end of the coil was a bit lower than the top of the inverted U under water when the water level was almost at the top of the inverted three quarter inch diameter U. There was no capsule or dome.
Omg carstairs siren G have slow start Up wow
So the whole purpose is to create a flush via a syphon with minimal moving part that can fail like seals, AND it has to work with older flush designs?
Yes, and I think by seals, you are referring to the ball value which requires maintenance (washer sometimes needs replacing). This design was for the automatic flushing of urinals before PIRs and solenoid valves existed. Every single public or school toilet that I can remember had one of these fitted. But it was flushing all the time even at night which must have been an enormous waste of water!
@@mrmattandmrchay Yes exactly, some would throttle the water down to a constant 1GPM. Seals like the fluidmaster which is most popular in the US that has 1 diaphragm pressure differential seal that always fails at some point.
Need more PIR vids
They're on their way...!
Great video Mat it is so interesting
Glad you enjoyed it
@@mrmattandmrchay 😁
Nadal nie wiem jaki jest sens tego
Huh it said this video is private before
forgot to upload video title photo
anyone here from mark felton productions?
Its for toilet
Please stop doing videos of toilet pipes it’s disgusting and I doubt no one cares the reason why I supscribed to this channel is to see old lifts not toilets pipes
I do sirens, lifts and really anything else that I find interesting. Sorry you don't like this video, but there are 600+ other videos, majority are lifts. I don't mean to sound bad here, but the content is what I chose to upload.
If it really bothers you that much... Just don't watch it? At the end of the day it's his channel and if he wants to make a video about a toilet then why shouldn't he? It's not exactly what I subscribed for but to be honest I went away knowing something more than I did before I watched it.
But he can't go travelling around to look at old lifts at the moment. The country is still in lockdown in case you hadn't noticed.
Get a grip... This is the clean water side of things - nothing disgusting about it!
Just install one of those in your lift machinery room , it’ll keep unauthorised personal out
