Drilling a DIY Well Using Air
This is a demonstration of airlift well drilling, a DIY method to create your own borehole. Airlift drilling is special compared to other methods because it uses an air pump (in this case a pump from an old air conditioner) to move dirt from the bottom of the well to the surface.

If you get in a rock how you mouve out the rock from your way?
I would buy one fiting that u ușe in the drill head with water in out pipes , anyone cam make to sell ?
T'es trop nul ... Tes tubes sont mal dimensionnés et l'air remonte par la sorti de l'eau alors qu'il devrait aspirer l'eau du bassin grâce à la dépression crée par la gravité.
Air is entering from the output side because the outpt is higher than he water level in the source. That is exactly what he tended to prove. This is a siphon, and no siphon can lift any water to a higher level.
@@kjellg6532 Sauf que son tube d'entré de sortie est bien trop gros et que l'air passe en "glougloutant" plutant que de créer une dépression dans le bidon pour aspirer l'eau du bas. Son installation est mal faite est pas du tout bien proportionné pour fonctionné. On voit très bien ici comment la dépression créer par le film plastique aspire l'eau. czcams.com/video/9eBf6_W0vlo/video.htmlsi=0S0aYu7tgAbcEMa6
@@magatst Now, if you dip the output side into a tiny cup of water, no air will enter and it all will come to a total stop. The water in the sucking tube may rise 1-3 cm, but there is still 1 m to go. If the tank is 100% fu of water, the flow will goo in reverse emptying the cup. N siphon can lift any water to a higher level. With both ends of a sphn is died in water, dimension of tubes does not matter. Input tube may be much, muh wider than the output side if you like. Purpose oof this video is to show that the set up with a tank, does not make a siphon to be a pump. There is no input of energy, thus no water can be lifted..

Dalam banyak vidio sumur.. Hanya ini sangat luar biasa kedalaman 100 meter memang manual tanpa listrik ❤❤❤
when the water tank run outs of air it will stop working 🤣
Anyone in the comments section ever dug a well in Southern AZ without a full drilling rig? If so, let's talk!
around my area of the eastern USA, wells are washed in. pressurized water pumped into the well point while it's pressed into the ground. these wells usually only go 12-20 ft (3-6m) deep. high water table around here.
Damn you didn't get your hands dirty at all did you?
Sir, Of the different methods you are able to implement, which do you prefer? Many individuals watching here will have both ELECTRICITY and HIGH PRESURE WATER at the worksite. Thank you. WMC
Please make this tool and sell in Lazada or shoppee in Malaysia. This is one of a kind. I need it urgently. I am in malaysia
So why can you siphon gasoline from a gas tank?
No problen if the receiving can sits on the ground, lower than the tank in car. A siphon runs from high to low, but a siphon is no pump and can not lift any water higher.
Pretty slick . I love watching people do considerably tough to complete tasks with intelligently designed equipment that most people would say couldn't be done . My favorite quote " Those who say it can't be done should not stand in the way of those who are doing it." Good job my friend
Thats a good setup you have there. I enjoyed watching.
Gaat het ooit zo droog in Nederland worden dat we dit nodig hebben?
You completely failed. That bucket is NOT sealed, and the pipes look very wonky, so no seal there either. The bucket lid is flexing down which breaks the seal. Not lot but enough to not let it work. In all the video showing this pump the tank is sealed air tight. You also don't have a foot valve/check valve at the bottom of the intake. I won't be responding to people who keep crying, and don't even know that most water hose sprayers use a siphon. I won't be replying to you asinine comments anymore. I have already proven you wrong on every point you made. And all you keep doing is repeating the same BS I already proved wrong. So when I don't respond again don't take it that I could not reply or that I could not make a proper rebuttal or that you "got me" in any way. Take as you are too stupid to reply to.
If this worked, we could scale it up and pump water around and around. Ad a geerator to the return water flow and we would have electricity for free the rest of our lives. At last Mankind have found Perpetuum Mobile. No energy input, just a water-Marry go round for ever.
I was watching interestingly but stopped at mud making.. Thats what killed it for me...
i do not undersrand what did he do at the end of the videi with this giant hise like vacuum cleaner!
Super!
Its easy if your land is compiled mostly by butter...
You are wrong it does work Your model is not correct Very simple, study old vintage water fountains some dont use river current, or pressure to work same principle
Sorry, but this video is correct in every detail. A siphon can not lift any water to a higher level.
NOT TO BEAT A DEAD HORSE BUT WATER RAMS ARE DEF REAL AND NOT FAKE
Yes, ram pumps are real and they work. This video is not about such, but about siphons. Some clame that siphons can lift water to a higher level, they can not. No power input.
I am wondering if a check valve is installed at outlet
No check valve are needed her, but the exit must be lower than the water level in the source for this siphon to work. To show this fact is the purpose of the video.
It's work you failed to make it work because you didn't prime the well side of this experiment. Furthermore, it would help if you sealed on the bucket. Just because you don't know how to do it doesn't mean it won't work.
Using a bucket you do not need to prime the suction side. In fact, that is the sole purpose of using a bucket. From the video you clearly see that the system is pulling air from the exit side. A proof that the bucket it airtight. This video shows that a siphon are unable to lift any water to a higher level.
Will it go through rock?
You don't know how it works. We'll test to see how long it takes to figure it out.
In this excellent video he shows that no siphon can lift any water to a higher level. No need for him to figure out anything - he knows it already.
By hand, without electricity... only 3 BLACK people working... do you know that slavery is abolished ? I could not see you delivering a drop of sweat in your video.
Your fittings are probably not airtight
You clearly se that the system is takig in air from the outpus - as expected. Excellent video!
Sorry to say that you missed the consipt of how this idea works. It's simply use vacuum inside the bucket with the help of gravity of the outlet pipe in the bucket to suck the water from the well. But something very important you should fix a rigged bucket in order to withstand the gradual suction that accumulates after opening the outlet valve.
This excellent video shows that no siphon can lift any water to a higher level. The bucket used here is perfectly ok.
Danm thats team work 🎉
waanzin.. mooi gemaakt.
Very nice video. My soil is different than yours, but EMAS has drilling videos for Bolivia, where it is almost pure sand, like my Florida vacation home. They have a lot of videos, and several techniques of drilling. but what you are doing is simper than their power drilling, and I already have a drill. Thanks for sharing your ideas.
What if we store enough water that put enough pressure on a small pipe to move it from lower level to a higher level?
Size of tubes does no matter at all. This is a siphon. No siphon can lift any water to a higher level. No energy input.
There is a lot of creativity in what some might consider a "crude" way of digging a well. Thanks for sharing.
Yay!🎉❤
What about copper pipe? PVC pipes leach microplastics
It won't work. Air pressure inside the tank will pull the air from the outlet. See how there is a space in the water going out of the pipe.. that's the air entering. It won't pull the water upward coz you know air is lighter than water.
Is this happening in Africa Is waking up ?
I want this guy in my camp when the zombie apocalypse comes.
In central California, the soil is bottomless sand, water is typically found at 175 feet but drilling your own well is highly illegal. It costs $75,000+ USD, takes a gov permit, requires a licensed well driller and a bunch of inspections. Everything is like this. Any wonder why everyone is leaving?
For a minute there you had four legs and four feet!
Excellent!!!
It workks. It has to do with the size of the pipes you used. The extraction pipe has to be bigger, than the diameter of the feeding pipe so it could initiate a difference in pressue wich will suck the water. Also it has to be air tight. Also, i you go deep into tge well you need bigger size tank and a check valve qt the buttom of the pipe plus some volume calculations t size the pipes correctly. The pipes you used are simmilar in size wich wouldnt work the why you heared that interruption sound.
Noop. Size of tubing does not matter at all. Input pipe can be say 110 mm and exit 32 mm, no problem. It is correct that the volume of the tank must reflect the volume of the total tubing from water level at the source till an exit lower than the source, this is a siphon! The system here is airtight, that is why it sucks air via the exit side since the exit here is higher than the source. The siphon tris to run in reverse. No check vale is needed when using a priming tank. This is the sole purpose of using a tank, to facilitate the priming of the siphon. An excellent video showing that no siphon can lift any water to a higher level, tank or no tank.
You amazing from Pakistan
Well, you can tell by the way he uses his hand drill he's a woman's man, no time to talk.
Instead of having everyone yanking on the rope to lift the "drill", you just need a counterweight close to the weight of however much you have added to the drill side.
Surely the lost water could be recuperated and reused somehow to make this setup even more efficient. I don't know anything about engineering or plumbing, but maybe that lost water can even be reinjected into the pipe using some sort of mechanical 3-way priority valve that prioritizes flow from one input and leaves it to the other input to satisfy the remaining flow capacity of the output pipe? But I dunno, maybe this is more complicated than I make it out to be.
Good job young man!
Try this experiment with the Top bucket closed (at least try to create vacuum) .
Thr Top bucket is closed, proven by the fact that the siphon sucks water via the output side. This excellent video shows that nonsiphon can lift any watervto a higher level, no energy input.
What is the drilling fluid thickening polymer called?
