Hydroelectric Turbine Pipe Burst Fail

I was due to go and change the hose on the turbine due to the poor quality of it. One day before I was planning to go and change it I got an email from the customer showing that it had failed. I already had the hose ready to go so the next day I went to fix it. This is just a quick video showing the hose change and getting the turbine back up and running.

[@YHBW1001]

I’d be more likely to hire you after this anyway. The fact you flagged the problem, fixed it and showed the whole story on KZbin shows something that money simply cannot buy…..integrity, honesty and transparency. If only more businesses (and politicians) acted this way we wouldn’t be in such a mess. Keep up the good work Kris,an inspiration to all.

this customer has 1000's of us mortals willing on his hydro electricity supply we also appreciate some of the wonderful engineering and innovations to make it work and could well help on the path to the ultimate utopian efficient hydro system(s), i love all this, watched Kris's videos back to the beginning, it's a beautiful natural progression in a world that is in many respects going backwards

[@saophaixoan7861]

It's great! My shed has been completed and it turned out nice looking and sturdy and it is way better than the sheds that many of my neighbors had put up.

He also said beforehand that the pipe was a bit suspect and needed to be changed. That is much better than "keeping quiet and hoping for the best".

[@I_Crit_My_Pants]

But none of this would be necessary if he hadn't bodged it to begin with? Typical contractor tbf, tries to squeeze by at the minimum and HOPEFULLY not face the repercussions later... Just cause someone admits fault AFTERWARDS doesn't change that they half arsed it to begin with... There are many other examples of how that kind of logic just doesn't fly.

[@duncanfrere2656]

The new hose looks properly stout! The whole system is so beautifully designed and constructed from top to bottom! From the weir and input gates, the way the pipe was attached to rocks with those custom-made brackets to the truly beautiful pegged-beam power house construction. The genius of the bespoke spoons and the way they attached to the generator in that custom-built stainless steel housing is really very impressive! So is that single-nozzle design! The whole terminal end of the pipe run in the power house is elegant and so beautifully thought out. It's built for a lifetime of use! It was great viewing watching it come together.

I have watched him since I found the channel and idiots like you can go fall in a hole. You on the other hand are probably a couch potato that couldn't tie his own shoes without help. Just so you know, and in case you didn't catch it, Kris does have to rely on other manufacturers' quality, and although he makes a few things himself, those parts have not failed. The customer was told about the pipe and decided he wanted it turned on immediately and he understood that a repair to a better product was forthcoming.

[@andrewallason4530]

You mentioned the effects of water hammer on the system. Something I like to do when installing gravity systems is to have a T with a section of vertical pipe to a cap near the bottom of the system. Air will naturally collect in the vertical pipe, any excess will just pass by. It will then use the trapped air pressure to remove the water hammer with no moving parts or valves.

[@darwinsfish]

Only just discovered Kris’s channel and over the moon that I’ve hours of fascinating viewing ahead. Amazed at the precision and attention to detail. I’ve worked in education and academia and have always been fully aware that there’s a kind of intellectual snobbery regarding those that make their living using practical skills. In my mind, the construction worker with their visual-spatial awareness, measuring and calculation skills, knowledge of regulations and technical specifications, adaptability and problem solving, use of multiple tools, pricing estimations, customer service skills, engineering understanding physical laws and much much more often trumps the university student memorising second hand knowledge to pass an English exam.

[@stickulari]

Great customer service, as it should be. I've enjoyed the whole series on this job, well done. You might want to think about using an inlet (male end) mounted on the wall not a socket (female) and a female end on the turbine cable both at IP67 rather than IP44.

[@Beansswtf]

If I was the customer I couldn't of been happier. You've done everything you said you would and more. They knew the pipe was a problem, but it would tide them over until you could replace it. No problem there at all, at least it shows them that the system does indeed work and delivers! I did have a thought about the draining pipe issue though. It would definitely be possible to have a float sensor in that tank at the top of the pipe, and if it starts draining have some stepper motor slowly close off the spear or main valve. Whoever you're working with on the pressure monitoring app/thing would be more than capable of programming this also.

[@MT-gv8ns]

If I remember right, hose manufactures will list the max pressure including a statement that it only applies to straight sections and may or may not include max allowable pressures in various bend radius. Turbulent flow also reduces the max allowable pressures although I would expect laminar flow in this system at the bend. Well done!

[@TurkeySandwichJr]

I had the same thought - that first pipe wasn't intended for a bend radius that extreme. The hose that replaced it is obviously more tightly reinforced. In regards to the electrical explanation at the end - I'm really not satisfied by that. Even if the conductor is less resistive, electricity takes all paths and this is a relatively high voltage 3 phase system. I think the water should have a shut off that is external to the building, for exactly the failure that was observed.

[@MT-gv8ns]

@@TurkeySandwichJr I thought about this some more: the corrugated tubing would likely cause turbulent flow with maximum effect, including low pressure bubbles and cavitation, at the outside of the bend radium; where we would expect the failure to occur.

[@rkan2]

@@MT-gv8ns It is onlt corrugated on the outside?

[@davidjones8680]

As some one who has worked with pumps and filter installations all my 50+ years of working life, I can testify that that green pipe is just about useless in any pressure side of a pump, it will always let you down, normally sooner rather than later. In any future installations you do I respectfully suggest you keep the path of the water to the turbine in a straight a line as possible, with no bends or radius at all, thus removing any uneven and unwanted internal side stresses on a flexible pipe. Keeping it dead straight eliminates internal G loading that occurs on any bend. It will also greatly reduces the possabilites of cavitation. David in Dudley.

[@KrisHarbour]

Hi David, the pipe is rated for suction and delivery. it is also rated within its bend radius and in this instance it is within it s max bend radius. There really isnt a practical way of getting the pipe to even enter in a straight line. If the turbine had one fixed nozzle it would be possible but a spear valve has to be 45 or 90 degrees. so in order to get the pipe in to it straight the pipe has to enter the building out of square or the turbine has to be mounted out of square. this causes its own long list off issues. If then any additional nozzles are added. (and its common for turbines to have 4 nozzles) it is impossible to get straight pipe runs. It is completely standard on turbines to use gradual bends to feed nozzles. if you look at images of commercial turbines even ones in huge power stations I doubt you will find any examples of a slight pipe run to the nozzle as it just isnt practical. In really high flow and head situations the pipe to the manifold is stainless steel or cast iron. But this is a small system and the solid pipe is not necessary. That length of pipe will last decades in this situation. I chalenge you to find me an example of a turgo or Pelton turbine with a straight nozzle feed pipe.

[@theminer3746]

I'm not an electrician but I can't help but notice that you're connecting the turbine to a plug rather than a socket (AKA, the plug is the power source and the socket is the power drain) that's dangerous since you can easily touch the metal leads in the plug. What you need to do is buy a wall-mount plug and a wander socket. That way, the socket is the power source which is safer. You might also consider an IP67 rated plug/socket (the one that you screws the cover together) so it'll be safe even when submerged like this. Bonus correction : Your plug probably have the earth pin at the 6h position, for 50-250V DC, you're supposed to use a plug with the ground pin at the 3h position. But I have no idea where to source that either...

[@TechOne7671]

Don’t worry about the hose Kris, it’s a learning experience. Try using some hydraulic hose. I have worked as an electrician in 2 hydro electric power stations in Scotland, they were both old and had been upgraded with new machinery. The thing is the new stuff is not all it’s cracked up to be, just new problems and issues to deal with. So even the multi million pound jobs are not perfect, far from it. Teething problems are still being ironed out years later. Your doing a great job, keep it up. All the best.

[@darrinduffey686]

Love your work. I have an idea that might help with water flow. If the water pipe wasn't as close to the top of your collector box intake and the screen filters, this would allow more water in the box. In other words, move the collector pipe as low as possible in the collector box. This would also allow you to put in a electronic water level controller device that could close the valve (electronic operated gate valve) at the bottom in the generator house so when there was not enough water flow you wouldn't have to manually close the valve. Just a thought. I hope this will help on a future build.

I like what you did and how you handled it. My only comments? Get a good first aid kit in the Landy! It'll be easier to work if you've got some nice dressings rather than a rag. I was thinking a small improvement might be to raise the 3-pin/Commando so it's comfortably above any possible waterline? I almost thought about suggesting rotating it by 90deg, but previously I've seen waterproofing lessened by sagging caused by gravity at an interface point.

[@AliC-uk2gp]

Hi Kris. You’re obviously a top bloke and clever to boot. An excellent system for your customer. I’ve worked in engineering for a long time both mechanical and electrical and safe to say I have seen numerous unexpected failures and I will second what a number of commenters have said that it’s actually how a person/company deals with those failures that determines how the customer views them. In this instance you dealt with it professionally and quickly. And what’s more you’ve improved the system. I’ve seen many parts fail prematurely only for OEMs not to learn from it and replace like for like. Personally I can’t stand regulations for this and regulations for that, most of the time I personally think theyre over the top and a product of a nanny state but unfortunately to keep ourselves out of jail we’ve no choice other than to follow them, so based on that, I’d second swapping the commando plugs so that the female end is on the “live” side and I’d also urge you to perhaps consider getting yourself on a course for the latest edition/amendment of the BS7671 18th Edition. The information you get will be invaluable to you going forward and whether we like it or not it’s the standard at which most electrical installations in the UK must adhere to. From the video (and I’ll happily stand corrected) it looks as though the cable from the turbine is SY Cable. This is currently not approved for use in the UK (you see it everywhere in industry but that’s by the by) and I do believe there is an effort to get it approved but I would consider reviewing BS7671 and using something approved. Good luck with your venture. I’m a mechanical and electrical control engineer so if I can offer advice on anything going forward feel free to get in touch.

[@AliC-uk2gp]

Oh and thinking about it, I’d come up with a way of guarding the spinning turbine. If anyone gets chewed up by it then the HSE will have a field day. Simple mesh guard small enough to prevent fingers touching it should be good enough, if you really want to be belt and braces it should also be interlocked to the valve so that no one can open the valve/run the system with the guard not in place.

[@TurkeySandwichJr]

@@AliC-uk2gp what do you think of having to walk into 6+ inches of water, with a spinning turbine potentially generating an unknown voltage in the middle of it, to shut the water down? I was really not satisfied by the electrical "explanation" at the end. Electricity takes all paths, and this is a relatively high voltage 3 phase generator. I think there needs to be an external (outside of the power house) water valve, or intake diverter etc to mitigate exactly the failure that was observed. I understand this kind of risk on your own personal system but I believe something for a customer needs a higher safety standard.

[@AliC-uk2gp]

Yeah, I’m not a fan of over regulation at all, in fact there’s that many obscure rules and regulations that it’s nigh on impossible to comply with them all. Unfortunately we live in a world where everyone’s trying to get one over on the next person or no matter what happens somebody has to be blamed and frankly I hate it. It’s that type of world (where we’re all trying to cover our arses) that makes me want to leave a more self sufficient lifestyle hence the reason I subscribe. As you say however if you’re doing this type of work commercially then it’s important “you cover your arse”. Maybe a simple lock on the door would suffice? I don’t know, but I certainly see your point.

I am looking in to getting the equipment to treat the weld sites. Its a problem with stainless steel welds. I clean them up with a stainless only wire wheel but they do still get surface rust. Its 316 stainless and in my experience it never goes deep in to the steel. it tends to happen in area that get the hotest. I think after a while the surface heals itself. my own turbine did the same thing and the rust did not progress. But I do want to address that with an electronic cleaning machine that seals the surface.

@@KrisHarbour Nice that you read the helpful comments, Kris. I watched the turbine series from the start and it's amazing how you've improved the design since the first prototype.

[@MrRitudo]

@@KrisHarbour Great choice of steel in moderately corrosive environments. So it should hold up a long time! But its for a customer so looks are important ;) the cleaning machine should do the job, no problem! :D Awesome to see that you think things through so much! Thats something I had to learn the hard way one to many occasions ^^'

[@wornoutwrench8128]

Been there a thousand times, manufacture decides the original was too expensive so go cheap or outsource. Get the part, open the box say crap to yourself, put it on so the customer can use his equipment, and tell him you will get a better one coming. Then you just hope the new one shows up, on time and is better quality then the original one. Good work. I just love that little system, such a clean install. Watching from the west coast of Canada.

The velocity of the water is way higher on the outer radius of the pipe than on the inner side the old hose propably got washed our from micro debris an the water velocity.

[@randyhooker3333]

Love your work and knowledge. You know your craft. And are honest and communicate the potentials to you client. Extremely rare today. You are inspiring.

[@The9Pauls]

How do we get on the list for one of those turbines? I'm in the US. Just bought a remote property with a 1/4ac spring which flows 1M gal/day

[@sicks6six]

there should be more businesses run like this, honesty, integrity and open,

[@bradholland6074]

Could you by chance use hydraulic hose like we use on our tractors? As always a great video. The customer is very lucky to have a contractor as upstanding as you

[@kuhrd]

When I first saw the new hose I thought it was hydraulic return/suction line hose and when he said it was only rated 150PSI I was thinking that it very well could be hydraulic return line. I was expecting a higher working pressure than 150PSI but that is a lot larger diameter hose than what I have normally dealt with.

[@thescottishwildman3245]

Kris, your a legend. Next piece of equipment you should get is the swaging machine for making hydraulic hoses. Make things a lot easier

[@togume]

Love this series - great work. Thank you for sharing. What is the purpose of the standpipe? I saw it in the other videos, but I didn't catch the reason for it. Thanks!

[@KrisHarbour]

Thanks, the stand pipe is there to allow the air out while the pipe fills. without it the air has to come out of the same place water is trying to get in. and it would take ages for the pipe to fill up after draining.

[@togume]

@@KrisHarbour ahhhhh!!! Brilliant. Thank you for teaching us 🙏. Looking forward to future videos.

[@poochna9229]

IT'S GOOD LOOKIN' OUT.. I WATCHED THAT VID WHERE U WERE A TAD BIT RELUCTANT ON THAT GREEN PIPE.. SOUNDS LIKE U OFFERED EXCELLENT CUSTOMER SERVICE & HAVE A MIND TO PROVIDE THE BEST U CAN.. CAN'T DO MORE THAN THAT , RIGHT? GOOD ON YOU. YOU CAN WORK ON MY HYDRO ANYTIME.. IF U EVER GET YOUR COMPANY EXPANDING TO THE STATES. BRAVO. RESPECT. Sis Margo-KansasCity USA

[@Lemma01]

Only serves to make one point, Kris - you not only can trust your judgement, but you have to! How much time did those wingnuts, and the fast pipe connector, save? Very best wishes for everything that you do. Oh, and carry elastoplast, maybe?

[@graemefisher7014]

What I have always liked about your videos us you are not afraid to show the stuff that goes wrong. Top video as always

[@williambramer8217]

Noticed that the old pipe had a corrugated bore and was not a smooth bore pipe which will massively reduce the efficiency. What is the temperature of the water ? If it is too cold the plastic will reach it’s glass point and become brittle and the turbulence caused by the rough bore can cause a shock loading.

[@KrisHarbour]

It is smooth. You can see the ribs on the other side from the inside but it isn’t ribbed on the inside. It has a very slight texture on the inside but it’s a lot smoother than it looks. It’s such a short length it would make no noticeable friction loss. To Say it would have a huge loss is completely incorrect.

[@Pithead]

I was about to post the same about the inner corrugation. He probably had it in mind. The new smooth more rubbery pipe will probably handle lower temperatures better than the old plasticky one.

[@0-Will-0]

Guess I need to add "suitable water source for hydro" to my dream plot of land for a house build. Would have no hesitation employing your services Kris!

[@mychalkeeney260]

Great content and it’s awesome you’re building/welding the hydro components in-house. Quick question - what’s the connector you’re using from the PMA motor to the wire along the wall… looks like some type of waterproof plug? Thanks.

[@simoncroft9792]

These are industrial connectors to BS4343 commonly known as CEE connectors or Commando type. They are harmonised to european standard IEC60309 . Blue colour is used for 230v AC they are rated 16Amp , 32 or even 64 The type Kris is using is IP44 - splash proof but they are also available as IP67 - waterproof. Red is used for 400v ( usually for three phase ) Yellow is used for 110volt supplies common on building sites for portable tools

[@moehunsinger724]

Outstanding series Kris! You are a true inspiration to many. I’m going off grid in the near future and wish I could get you here in the United States for your great wealth of knowledge! Keep up the excellent work

DO NOT work with bare hands - use gloves and mittens .... It's still young, everything heals quickly, AND THEN EVERYTHING WILL COME OUT ... Take care of your hands and everything else !!!!

[@VFRrider]

Sadly, gloves cause a massive lack of dexterity. Personally, I can't use them. I need to be able to feel threads biting etc. I can't even work with surgical type gloves. OK for lifting/ carrying, bloody useless for fitting 8mm nut!

[@MrPetrvershinin]

@@VFRrider dexterity it’s not needed here, everything rather stumbles upon a HURRY, - I want to see the result as soon as possible, - the work can wait or do it slowly, AND THE HANDS AND FINGERS ARE ALONE AND THERE ARE NO SPARE ...

[@stephenb5595]

Done yourself proud taking ownership of problems before they happen. That's what customer service should be like everywhere. Loved the video and like you show both the good and bad side of things.

[@daniellittle7846]

using SY cable is not rated for that kind of application to take the power off the generator its not corrosion resistant

[@evanofelipe]

It’s to your credit Kris that you readily replaced the failed connection pipe. I bet you are your most severest critic and no doubt kicking yourself for not addressing your doubts earlier. So far as the suitability of the original pipe, regardless of it’s rated maximum pressure, it’s worth remembering that these tests are generally conducted with newly made pipe in ideal temperature controlled conditions and when you removed the old pipe you noted it was brittle. In this working environment, albeit protected from direct sunlight, the material had been exposed extreme temperature variations experienced in the hut from hot summer days to cold night conditions on a Welsh mountainside, let alone constantly subjected to high resonance vibration created by the turbine to which it was attached. This failure can be put down to ‘experience’ and Murphy’s Law. If it can go wrong, it will go wrong. Well done.

[@MalteseMafia]

Great customer support which is the important thing. How about making a shut off valve on detection of a leak. This pipe might need to be replaced on regular basis to prevent this happening again. Great honesty too, other people wouldn't show this failure.

[@ForgedInHolland]

6:30 are you not afraid of you or something else falling into the turbine? Maybe a safety cage would be a good idea.

Just found your channel, amazing work by a very skilled person, I have so much water here but no head which is a shame as your skills would be employed in a heartbeat.
