Speaking of cleaning, I could stand to remove some of that algae on that glass! That stuff just never stops growing =P
What the Python is accomplishing and you're attempting to accomplish is in creating a "venturi". This is the inverse of Bernoulli's principle of flight. Picture the wing of an airplane. The airflow underneath the bottom of the wing (the flat part) is traveling at one speed. However the airflow above the wing is bending around the curved shape of the wing and therefore must increase in speed in order to equalize. As this airflow speeds up over the wing, there's less time it spends on the wing. Because there's less time on the wing, there's less pressure being applied to the wing, thus creating a pressure imbalance. The "normative" air flow above the wing therefore becomes a "low pressure" system, and the air flow beneath the wing becomes a "high pressure" system. The high pressure pushes "UP" against the low pressure creating lift. Now take that principal, and flip-it upside down. Instead of creating lift (Bernoulli), we can use the Venturi principal to create suction. The Venturi principal is at play when the Python nozzle tip is narrowing down to a smaller diameter. By narrowing the diameter, you increase the pressure. Take for example a garden hose. If you place your thumb over the top of a running hose, what happens? The flow rate of the water hasn't changed, however you're forcing the same flow rate of water through a smaller space which increases the pressure and you can spray further. The same is true here...by the narrowing tip of the Python nozzle, they are creating pressure imbalance which is creating more suction that your home made model. So if you narrow the diameter of your nozzle tip, you too will achieve the Venturi principal of suction and thus replicate the what the Pyton is doing here.....and yours will be indestructible. :)
I intend to try this with a few amendments. It's a great idea for a far more robust system.
1) By attaching a small guage hose to the bottom under the blue valve you will create a better seal in the outlet, hopefully preventing air going back into the long pipe. Thereby creating more effective suction.
2) By lifting the bucket and reducing the "head". Most tanks sit on a stand about 3 feet off the ground, not on the floor. Most taps sit at about the same height. The more height difference (head) the more pressure you need. The lower the head the better.
3) filling the long hose with water first by changing the valves and pumping just enough tap water into the tank to empty the pipe of air, also known as priming.
4) Shortening the hose length (less air/water to suck out) you will minimise the pressure required to draw water from the tank.
Hope this helps.
addendum to 1, by inserting the end of the new short hose into water, any back-pressure would suck water into the system rather than air. @andrewesquivel
Saved me 55$ haha was going to try all that on my own till I saw your video found the python pump on amazon for under 10 bucks so going that route.
Yeah, you could buy FIVE of them for what this guy paid for ONE.
Update, bought the python pump part for 4 bucks and the tubing for about 10 bucks, and two 3 dollar adaptors for the barb to hose attachment an old vac with the anti backwash broken and it works well... I was going to try and make the pump out of metal but after watching this video I saved about 10 to 15 bucks and just ordered the python pump on amazon.
The original cone shaped fitting from Python increased the velocity of the water. This increased velocity is what caused the vacuum/suction. Read up on Bernoulli’s Principle and add a fitting that drastically increases the velocity of the water and it should start to work.
David Lee sh!t using “principles” we’re gettin’ serious now people 😜🧐🤓 Regards Duzzy 🇦🇺
U r right on the principle. Just make a similar piece in copper and then it would resolve the problem
You really dont need a huge amount of suction.remeber that you usualy did it with your mouth...now.did you tried filling the hose with water end rapidly changing the direction of the fluid with the hose full??
You are a gentleman and a scholar sir!!!!!!
Just a suggestion - instead of the faucet adapter, you could go with a quick connect fitting!
I've been searching high and low for a tutorial like this. Thank you so much. I've gotten annoyed with the cheap aqueon pieces that strip and break. Its unfortunate it won't drain, but filling is more than enough.
Suction from the tank can be done quickly by installing a submersible electrical pump while filling the tank using Aqueon or Python or your modified metal fittings, but due to the increased number of joints in your metal modification, there will be an absence of vacuum creation.
From what I've seen, maybe the system works. I have the impression that even the original devices would not be able to suck the water much above the level of the faucet. It should be observed that the tank in the experiment was at least 1 meter below the tap, therefore, a very strong suction would be necessary to overcome the water column (remember that the highest suction pressure that can be made from air at the sea level is 10 meters of water column). Perhaps, if the hose in the experiment of the video were translucent, it would be possible to see the water a few centimeters above the tank level. In my opinion, the device is useful to suck water when the faucet is below the level of the reservoir, that is, an automatic siphon is made as a result of the faucet flow, even when the inlet of the hose is removed from the water. Perhaps a solution to this problem (faucet level above the water tank level) would be to extend the device, using a hose at its outlet, so that the end of this hose becomes lower than the tank level.
Thats a good idea just for filling, I use a submersible pump to drain as the python fill and drain things waste tons of water. You could make one for filling out of PVC as well.
50 years ago
i have been using (and had invented for myself )a simple system with a siamease valve ($3)at the sink and a garden hose.and faucet at the tank
it simple as long a my hose in the sink side is lower than the tank level
been using it ever since.
The problem with your system is you don't have a narrowing just before the opening to the hose. It is called the Bernoulli's principleand that is what python and aqueon use to get the water flowing by the opening to suck. That part of the system is the venturi principle.
System is not air-tight to create a suction, notice the leak at 22:00 - this is like you've a hole in ur straw. This is In addition to what people have already mentioned (venturi effect to create more pressure, keeping the bucket higher to reduce head, etc)
What is the part number for that non-brass piece you add at the end? The one with the threads on the outside and inside of the pipe that you're using to mount that extension insert inside the top section of the Tee fitting. I do not see it in your parts list. Neither is the ball valve you used between the hose and the gravel vacuum end. That inner insert itself is LFA-786, yes?
From the lack of any follow-up videos, is it safe to assume you were never able to crack the suction part? That's a shame. It's pretty useless without the suction action. You can skip the $55 worth of brass and just run a straight hose from the faucet to the tank if all you want to do is fill. The entire utility of the Python's clean and fill valve is in the suction action. Any plain old garden hose can handle the fill part just fine.
Awesome, thank you!
it seems pretty clear from the comments that this is 95% done and just needs a narrow nozzle tip inside the T part, and even seems like someone already did it @Tha G so maybe @andrewesquivel you can find the nozzle tip that creates the venturi effect, re-upload and claim your crown? XD
Did you ever clean that sink?
You have to make the inner tube much smaller you have to make the water jet threw it that why the plastic one is coned and a smaller end
Interesting, wonder how much of a difference it really makes
What you have to achieve to allow suction is the venturi effect. You can find tutorials on diy systems
Reduce the diameter size of your inner drop piece to increase the pressure, the only difference I can see. Try running it and see if it makes a spiral pattern running the water.
To be honest you're probably not mad money I get that but the best way in my opinion would just be to get an engineer a plumber and a physicist whoever else you mentioned on the project to perfect it
Keep in mind you may need a different faucet adapter because some faucets have inside threads or outside threads.
I believe it might have something to do with the size of fittings used’ try to mimic the sizes of the plastic fittings’ ;)
I need a male part on top to to go into a female faucet, wish you had shown both ways & also shown us how to change it over so we could use the clear hose & Python attachments to clean our gravel. You did show the piece of garden equipment to disperse water, great, not exactly what I was looking for.
Hi mate such a cool vid that god a DIYer version for those inclined. Quick question bearing in my mind this can work need validation. Can the gate valve go the other way so the lever goes up rather than down? I’ve never used/seen one. Regards Duzzy 🇦🇺
Did you ever finish this
I have built upon your foundation and have indeed found a way to make it work!
Awesome!
THA G care to share?
Can you share what you added or did to get it to work please?
The water from the "tank" needs to be at a higher place than the sink. Gravity is what helps it get "sucked" out and down.
You need to look up how to make a venturi
This is a pet peeve... making "how to" videos where the guy doesn't know what he is doing. This is a 25 minute video where the guy ends up asking US how to do it.
Holy crap, I just spent ten minutes doing research and watched a "how to" video that told me nothing. I am actually pissed, blocking this guy. Don't waste your time folks, not if you are hoping to see what vid title suggests.
All the while sounding condescending.
Its cheaper just to buy one from python.
Dude the title says "how to" not "how do i?" Why are you wasting people's time?
So...did you NOT see the first 10 seconds of the video that calls it a work in progress?
Just bought 11 of these on Amazon for $55 dollars. Be here by Monday!😉🤪👍
For f's sake Amazon has the entire python assembly for $5
