for your overflow side, why not just have the old toilet tank stopper attached to a float on a chain that will lift it up just enough to keep the gutter full but not overflow. So once the level drops back down, the float will drop and seal off the overflow.

[@TheLightningStalker]

Until it freezes and then everything that isn't flexible enough to take the expansion will burst.

[@wvance0316]

@@TheLightningStalker Water in the bottom pipe will drain automatically. Water in the Siphon will either have a large pocket of air or it will have emptied from being too full. Water in the gutter can expand upwards. So where do you see this water bursting things?

[@Observ45er]

As an experienced engineer I can say this is quite an awesome little project. I see two requirements you don't seem to quite directly address. ... In order to get the Bell siphon started the outlet pipe must completely fill with water across its cross section. That is how it draws the vacuum up at the top to get started and operate. Then, the diameter of the exit pipe must be large enough to support the maximum flow. That first problem could be solved with a small valve at the bottom of the drain tube that opens when the height of the drain tube is full that would rob the least amount of pressure from the starting condition. If your generator can only support so much flow and it varies too much during maximum rain, you're going to need an additional reservoir to hold that extra water, or as you have done, provide an additional overflow to simply dump that extra water. ... .. .. It also seems like your paddle wheel turbine is rather inefficient. Since you've got 3D print capability, you might be able to manufacture a more efficient turbine to extract more energy out of that head of water from the gutter down to the generator. Anyway, I hope these suggestions can provide some help. You have a very unique solution to using something that sits there all the time with no purpose other than to keep water from dropping on the lawn. Cheers I just stumbled upon your video and I'm pleased to have done so. Also, the drawing animation is quite impressive as well.

[@fermitupoupon1754]

There's no real need to have a valve in the system. Having a funnel as the outflow pipe make it much easier to start the siphon. The circumference of the top of the funnel can be considerably larger than the pipe it's feeding into. This effect is then compounded by the increased speed of the water entering the outflow pipe, which makes it easier to draw the slug of air along. Combined with a properly designed p-trap with a few add-ons you can get a decent size siphon to start at quite a low rate of flow. The p-trap with add-ons, if you're making it from DIY store parts would be 2 90 degree bends as the inflow, to make a 180 degree turn. That feeds into the bottom of a T-joint, with the top capped off as a small air trap. The horizontal branch of the T-joint then feeds into 2 45 degree bends so there is a small drop, which then feeds into another T-joint, placed horizontally. The second T-joint has the branching opening pointed up into an open stand pipe to vent the air. It's kinda hard to explain without a picture, but I'm sure you get the gist of it. And while not important in a prototype like this, the smaller diameter pipes in the siphon would ideally be made of brass or copper to prevent clogs from organic growth. I don't have any engineering training in this matter, but that's just my experience building ebb-and-flow hydroponics systems. The reason to use bell siphons there is that you want as few moving parts as possible. Starting a bell siphon with the low rate of flow that a pulsed geyser pump delivers, is mostly flux calculations with a wee sprinkling of black magic and voodoo.

[@nathanvanlieshout7834]

@@fermitupoupon1754 I was thinking a funnel on the exit tube would help.

[@Londubh]

@@fermitupoupon1754 Why a P-Trap, rather than an S-Trap? The benefit of a P trap over an S trap is that the P trap maintains the water seal... but that's no a concern here, so wouldn't it be simpler to just use an S-Trap?

[@fermitupoupon1754]

@@Londubh In my experience, so n=1, a p-trap has the benefit of triggering more of a flushing action. It takes a bit more to reach the critical pressure in the bell and down tube, but once that pressure is reached, the p-trap will flush and suck the slug of air with it. So it's more reliable to start, especially with a lower flow rate to start it.

[@Londubh]

@@fermitupoupon1754 but that doesn't make sense to me. The triggering of the traps is going to be purely a function of the relative heights of the top of the second curve/horizontal-ish but. Indeed, I would go so far as to assume that it would trigger faster with an S because it wouldn't require as much water to fill the top of the S compared to the (not quite) horizontal pipe of the P. Indeed, the reason we've moved to P traps is that S traps tend to "flush" the "trap" out, thereby allowing sewer gas into the house.

[@russelltalker]

@@madscience6283 I often feel like that too trust me, but then you gotta understand this is not a registered media company with a crew and office building and studio creating content for millions of people on some national Television network with hired experts, writers, presenters and a budget. And even then they pretty much always fuck it up, and land short of perfection. Its a guy, at his house, on KZbin. Just do what I do. Double tap right side of screen a few times. I just about got done explaining the most basic shit to partially convinced younge people like how lightyears work on a video on astronomy and cosmology in the comments section. I guess some people need those balloons. Also practical engineering is hard to watch these days. It used to be very inspired and you can tell because the content holds your attention. Then like pretty much every successful youtube channel ever created, they blow up, optimize and streamline and maximize revenue. Which is exactly what I would do if I were them but then the content is no longer inspired. Its boring! I can't watch it anymore its like reading wikipedia, but from start to finish. Listening to practical engineering is like somebody reading you a textbook on the history of engineering whilst you're tucked in bed, as he interjects here and there with a clarification or two, before suddenly and without warning he reaches in his pocket and without breaking stride pies you right in the fucking face with a buttload of advanced maths (atleast the me). We didn't all do math and engineering after highschool. Some of us didn't even finish highschool. I suppose wikipedia does that too. But there it fits. The maths thing is kinda ridiculous. Its like saying halfway through, "oh btw I forgot to mention this video is for people who know calculus and went to college, sorry about the rest of you. And im not even saying I never ever understand the maths part. Just almost never. Edit: sorry I mixed up practical engineering with real engineering. All good channels though

[@2adamast]

Not sure, the explanation works with three concepts, communicating vessels (can work within limits in near vacuum), siphons (can also work within limits in near vacuum) and pressurized systems ( like here a siphon with an air pocket) . I had to check internet to get the explanation right, as one idea doesn't explain the others. The plus is by checking internet I learned something. (edit the () parts)

[@eisenklad]

to solve your rain gutter overflowing in heavy rain, just add a weir around the overflow drain opening. so when your gutter is about to overflow, it will drain according to your weir height.

[@QuintBUILDs]

Yup, I think that's the best solution.

[@Mate2Frio]

Weir were you earlier?

[@TheCapt]

@@QuintBUILDs Should be able to do it on your other gutter outlet. I would think a collar around it with the height you want for overflow, then if you want to help keep debris out of it, you could just put a cap over it. For the other issue with the dribble, I thought maybe a tipping weir might work. Basically making a dam that has a section (L shape) that would tip over when the height of the water overcame the weight of the section. When the section tips over, the lower section would be 'pushed' by the flowing water keeping the top section down, then when the flow decreases, the lower section drops back down and holds the dam closed. You can adjust the weight of the lower section to meet the minimum and maximum flow.

[@LeRainbow]

@@TheCapt I think it would be easier to use differential mathematics to describe the dynamic system to then engineer a pump, hose and valve system that measures pressure, water height and maybe flow to determine via a PID-Loop how much water to pump off to never have any overflow at all! I hope you understood the joke in this, I liked your enthusiasm in wanting to find a solution to this problem mechanically or better said ... failsafe without any extra energy needed to be put into the system.

With higher flow rate at a higher trigger height maybe

[@wilcoslegers8281]

Or add a reservoir at the overflow which dumps its contents when the flow into the overflow stops. Additionally you can add a small foam float valve on the intake to the syphon which gets buoyant once the water gets high enough. This should trigger a more sudden inrush, triggering the syphon to waste less trickle.

I've built a few Bell syphons for aquaponics systems and I would recommend making the brim of the outflow pipe a larger diameter to give more flow faster and activate the syphon quicker and with more force. Basically you want some sort of a disc or washer on the top of the pipe. I use 20mm pipe for my systems and I just put a 20mm > 35mm adapter on the top of the pipe so there's a larger surface area that the water spills over from and it creates the airlock faster and triggers faster. Hope that helps with future projects, keep up the good work as you've just gained a new subscriber 😉

If he did the math he could figure out total possible volume of water per minute for his roof during highest record rainfall and then know if he needed 1 or more extra downspouts with generators attached to each.

But he could test to confirm in next video :)

Yes, also the siphon starting height is limited by the max gutter height. So the waterwheel bell siphon needs to be lowered so it could start earlier than the high throughout siphon. Testing would be a little annoying, can easily test each side of the system separately for functionality, but proving the system as a whole may require another heavy rain.

Would have to lower current one and add max one. Giving you high and low rainfall. May need to look at max rainfall per hr and roof area to size it to match worst conditions.

For better usable bandwidth you could always have multiple siphons set up at different heights. So it starts siphoning at a low level, then if that rises higher the next siphon also kicks in, so on and so forth.

From experience working with low flow aquaponics, you're missing the equivalent of a sink trap just below the siphon so it has an easier time getting the initial seal.

[@robbieaulia6462]

The emergency overflow should be automatic, you can do this by simply making the overflow pipe's hole at a higher area so that the bell siphon can work at the same time

[@LilJonny]

have it feed into the overflow past the bell siphon for better efficiency

[@BobHannent]

Either raise the height of the inlet for the downspout by inserting a sleeve tube, or add a float valve.

[@NumquamDeorsum]

Theory: You can achieve much more head pressure by reducing the size of the downspout. On the opposite end, redirect the downspout, a 45 degree angle from the gutter towards your wheel. Every 4 feet, reduce the pipe size by one inch. You will generate way more speed. This is how they used to do hydro excavation during mining operations in the 1800's.

[@2adamast]

I think a 1/48 (1 inch every 48 inches) cone is unnecessary, a 1/5 is also ok

[@halomanXP]

Disclaimer: no science or engineering experience just an intrigued person. For the overflow, would it be possible to have something like a second bell syphon but trying to change the height it triggers as to make it 2 cm below the edge of the gutter, this might be enough for rain coming in at set rate, also I'd adjust the Bell syphon to trigger at 4-8cm before the Overflow, depending on the flow rate of this first one. Note overflow syphon opening should be at least 75% times larger to be safe that the syphon rate would be sufficient for the rain fall. (Keep in mind that original syphon is operating but overflow should be designed for failure of the first (it should be able to drain as if it was the only one operating and at a heavy rainfall rate). Thank you for your time.

[@mikehealy74]

That does seem a brilliant idea. Or, for the sake of keeping it simple, notch out the gutter at the top, on the end or the front - then attach a downspout at that notch, so that any excess water just flows away, and doesn't rely on any systems which could fail, become easily blocked, or be overwhelmed.

[@mikehealy74]

I had another, even easier thought. At the other downspout, which is currently blocked off, extend the outlet up, so that it is below the top of the gutter, and at the top of the max water level you want to hold - job done.

[@qapla]

Nice demonstration of the bell siphon - and a good, simple explanation of how and why it works. It may be worth noting that guys who setup and level mobile homes have been using the water-tube level for decades. They use very long clear tubing filled with water. They clip one end where they want level to be and move the other end from support pillar to support pillar to level the house by jacking up and shimming each position until the level read the same at each pillar. I have seen (and used) some have 100' of tubing.

Thanks you for a great series of videos. Very informative, and also _fun_ to watch. A friend and I are going through very similar steps working on a micro VAWT. One thing i already discovered before seeing your videos was that replacing the ball-bearings in the cheap Chinese alternator we got makes a huge difference. I have two tips for you, regarding the bell-siphon: 1) give the drain-tube a slight narrowing, a venturi-like shape, at the top. Or maybe just flaring out the top of the tube into a slight funnel-shape might do it. And make sure the top edge of the tube is level, of course. 2) put a second bell-siphon, set to a slightly higher trigger-level, in the drainpipe at the other end of the gutter as an emergency overflow valve. Cheers! 🖖

[@picashlio3361]

This was one of the most fascinating topics covered in my auto tech courses. Not sure if siphons are covered under Pascal's law or some other but the water leveling out in the two glasses makes sense because both sides are exposed to atmospheric pressure and are sitting level. As long as the tube to the bottom of glass A isn't raised above the height of the water level in glass B or vise versa the water level will continue to level out. A sudden change in elevation in either glass- like is achieved by raising one glass suddedly- will cause a change in pressure forcing the siphon to drain the glass accordingly. This is a similar concept to the one used to make a brake fluid pot work. You fill the pot with brake fluid, put the top on (it has a tube that runs to the bottom) then pressurize the pot with air. It pushes the fluid up the tube due to the difference in atmospheric pressure and the higher pressure in the pot.

[@WernerBeroux]

I think it's time for a double level Syphon where one helps to trigger the second by rapidly increasing the water flow. The KISS option is to level the tube entrance 🤣

If you have all the water drain into a tank or 55 gallon drum and connect a fitting that connects to a hose and put in a mechanical pop- it valve that will pump water back up to the gutter you can keep the cycle or water ( recycled) so it will not run out! Now you may need 2 or more pop- it valves to keep the gutter to the right level! Just thought this would work with rain or just fill the system and use float valve connected to 1 of the tanks to add water from your water hose as needed! This will give you a continuous loop even if it isn't raining! I enjoy your channel and you seem to have ideas that roll around in my brain all the time and it's great to see them in action and then I take what I learn and add it to what I've been thinking!

Would putting a “P” trap in the discharge line help it build up enough water to prime flow out quicker?

[@stephenwhite1607]

NO, It doesn't work that way.

[@AL-cy8zk]

@@stephenwhite1607 Actually it would work as David Unger says. The P trap would create an airlock that prevents the main syphon from dripping while the gutter gets filled because the air in between the main syphon and ptrap needs to be compressed while pushing water from the ptrap out down the discharge pipe. When the gutter water level rises high enough, the P trap air lock is broken and that causes a surge of water for the full flow of the main syphon. The P trap needs to have an air vent to prevent all the water from leaving because it does not self prime. A video of a ptrap in this use case kzbin.info/www/bejne/a6i9aoOHmtWEj6s

[@ryannorris6128]

Great video, and a fun project. For the overflow condition, a simple fix would be extending your blocked downspout up into the gutter to a height just above the start height of you bell siphon and below the top of your gutters. That would act like an emergency spillway and keep your gutters from overflowing under heavier rainfall.
