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.
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 TH-cam 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.
I agree, Mark.
100% agree with your comment.
Yup, totally agree.
Absolutely. I live in N Wales and if I needed a system like this Kris would be my first choice. He's on it. Dave
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
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. Of course, I'm pleased with the outcome and this Ryan's th-cam.com/users/postUgkxGZedDTcDfgD7fG_uU4esfx_EgxzlY2_1 Plans was extremely useful to me as a guide.
Customer service is EVERYTHING - things do and will go wrong from time to time - how they are addressed is the real deal. well done Kris for your actions.
Absolutely 100%!
Agreed great service is the reason people come back and you build a good reputation
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".
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.
@@Muck006 No, he literally kept quiet and hoped for the best, otherwise he would've fixed the pipe before...
“Unfortunately that’s all I’ve got for ya…” 😆 Who else besides me LOVED this episode? Thanks for posting and sharing Kris.
We love everything Kris does! 😂
You come across as good guy
kris, watched you since the beginning mate, try not to get into the weeds justifying your work, or dealing with youtube warriors. You're an absolute legend, your work speaks for itself, I bet 99% of the people that give you grief through the comments can't do half of what you can do, to the degree you do it. Keep pumping out the amazing content, your finished products speak for themselves and theres been so many of them through the years, things are always gonna break or not work perfect first time. as everyone above me has already mentioned, we'd hire you in a heartbeat even before this level of honesty and justification!
You can take solice in the fact you'd flagged it to the client and on the video. I agree that it looks like you've been sold something that the manufacturer has scrimped on, not your fault at all. Hope your thumb is on the mend. Kudos for showing even when things don't always go as planned (even though you'd predicted it).
the first hose , you were able to tear apart, the second one fought back! Ouch.
Mate imagine if all hydro companies were this transparent and honest. LOVE this series.
The work you do is of the highest quality, you flagged the potential problem.and dealt with it in a very speedy and professional manner, I doubt for one minute that this would impact your hydro business and you didn't have to show the video in the first place, your transparency and honesty are what makes me/people enjoy your channel even more, keep up the great work and look forward to seeing even more of your build projects.
He flagged the problem and waited for it to break. Could have ruined the whole job site.
@@TheMrCheezlezombie Have you got "ANYTHING" you can show us that you have done? Let us pick apart something that perhaps you have done.
You didn't listen to him did you? Just came to the conclusion that he was unprofessional and could care less about what he does. There are two negative comments from you so far, and hopefully, no more will appear. There are a lot of folks who like what he does. You don't, so leave!
I like the way he has the spirit to take on challenges and gets the job completed. 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.
Have a nice day and go somewhere you are respected because it isn't here!
"Highest quality" yet he left something he was concerned about which caused this entire problem later... Half arsing the job in the first place caused this entire issue? What?
@@TheMrCheezlezombie Exactly, glad everyone down here isn't a mindless fkn sheep, thank you.
Never would I have imagined this would be so facinating. I swear if Kris explained the technical process of watching paint dry, I'd be riveted to that too! From buildings to cider to solar to garden beds to farm animals to metal working to hydro to vehicle maintance to that harp... wow.
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.
Thanks for your channel.
What Duncan said (way better than I could have said it)
@@timjames2654 Yh what Duncan said 👍 in fact I think we should just leave all further comments too Duncan be honest...
Sounds like you've had your fill of internet commentators. Well done on having the facts and knowing your craft.
At least you called it and was ready with the replacement before it happened.
NASA have....you called it, thank god no astoanaughts were trapped in that valley pod
My first thought was "That looks dangerous" and my second thought was, "But this is Kris. I'm sure he would never let that happen." I am so amazed and inspired when I reflect on all Kris has done with this channel and his homestead.
I'm very thankful that kris shows these things too. It is strangely inspiring to see the full picture including the problems. I feel that some of these channels are selling fairytales whereas I'm actually bolstered by the fact that kris shows that when things go wrong, you just solve them. Thanks a lot for the inspiration and honesty kris!
There was no honestly. He was dishonest by installing a part he KNEW was bad. That's a complete lack of integrity.
@@TheMrCheezlezombie He was honest with the customer about the problem, and customer made the decision to go through with the installation of a possibly faulty hose. If there is someone dishonest, it's the manufacturer of that hose, who sold it with characteristics that did not match the performance.
@@TheMrCheezlezombie The customer wanted the system running as soon as possible and was warned about the low quality part. Kris already ordered the better quality part and set up a date to replace the low quality part with the customer so the customer could still generate power in the meantime while being aware of the issue.
When your not happy with something, we can count on you to change it!
What I think is the most endearing part of this video is that you didn't hide it. It went wrong, (you knew it would!) but still showed everyone what can go wrong and why and most importantly when it does, customer service is top priority.
Great work Kris, keep the content coming.
"Your best teacher is your last mistake" .... but you didn't make a mistake, yet you still learn/adapt .... top job and nice summary at the end matey !
Wow. Ive been in the HVAC industry for the past 30 years, 20 of which in the commercial. So refreshing to see somone so professional and committed to getting it right. Thanks for your informative and addictive channel. Never to old to be taught!
Yet another cracking video that show what a perfectionist you are, and what good customer support you are giving. Just a reminder that you still need that drip tray at the top at the bottom of the inlet grill to shoot the water over the connection of the pipe to the collection tank.
You should have installed a port for a hose bib on the "reduction flange" so you could spray down any mud in the shed at any time or water the flowers around the building! 😄 I enjoyed the entire series and very impressed with the skill sets and all of the "toys" you have. Thanks for sharing!
Thanks for posting Kris. I am sorry that you still get "experts" telling you what you should have done! In all the time I have watched your work I have continued to be impressed with your skills, honesty, and openness. Well done keep up the work I always look forward to your postings!
Kris don't feel like you have to justify yourself to the Internet mate. 2yr warranty and a early morning callout to fix a faulty part is top service. sometimes things just fail. You continue to do a solid job for your clients and are inspirational and educational to us voyeurs of the Web. thank you.
When you order high pressure hose and they supply a McDonald's paper straw 🤣 glad you got sorted 🙂
Think a maccy D straw would done a better job lol..
That is the best comment ever😂😂😂😂😂😂😂
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!
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.
@@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.
@@MT-gv8ns It is onlt corrugated on the outside?
Good on you mate. Taking care of your customers professionally, quickly and correctly. Be Safe out there
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.
It’s just cracking me up listening to all your explanations about what happened. I don’t know why anyone would question you at this point. Your Brilliant!!!!
I can’t say this enough, I’m truly learning a mountain of info from this channel, and enjoying every bit of it. Thanks Kris
Its had the blood sacrifice. That pipe will never fail now!
Really appreciate your honesty about the problem. The green pipe always looked cheap. The black one looks great. Overall, very professional. Thank Kris.
Great follow up. Bloody Thumbs up
Looks like camoflex, it’s great for suction, but not good for pressure, it always goes brittle and cracks.
Dude , you are living a really great life and are actually making a great contribution with your business, - will say you shouldn't worry about addressing your critics
Trials and tribulations of starting a business. Thankfully you have a really reasonable customer.
I watch this from USA AZ as a British person I am amazed at your Skill level great to watch thank u oh also my dad's brother was the mayor of Wales (Ron Kirk) FYI
This is a great system but is there a reason for not having a cheap and simple guard/screen covering the turbine. I know it's inside a building with restricted access but the owner or you would get seriously hurt if they slipped and fell onto it or placed a hand down to stop their fall.
For such a young man your skills and work ethic are off the charts. Your generation don't believe in hard work sadly. But thank God there's you and a few others to carry on these skills and hopefully pass them down. This might very well be the most useful TH-cam channel on the whole platform. If you were my son I would be proud as a Peacock! AWESOME WORK!! AWESOME OUTLOOK ON LIFE, AWESOME PERSONALITY!
Nice work mate, problems always happen, making sure they are sorted quickly and properly is the key which you have done. You seem a good guy to do business with.
"Treat others as you would want to be treated" is a great mantra to do business by, and you appear to do that in everything that you do. Nice work as ever.
Thank you for sharing both your wins AND fails. It's nice to also show how to fix potential issues and how to overcome adversity.
Thank you for the update video! Love catching up with you and seeing how you are doing. Glad all is well and look forward to more!
Jeez, I haven't watched your channel in a long time, glad you're still doing good!
I agree with all the other comments on this video that is your work is of the highest quality. Wow the effort and quality you put into this small hydro plant is more than professional it is outstanding. If you were in my neck of the woods I would hire you for sure every time. Great work amazing quality and outstanding service!
I’ve been watching your videos for a couple of months. It’s exactly what I’ve been looking for. I have a spring well on my property and am trying to figure out how to make a hydro set up like yours along with solar and wind. Really appreciate all the detailed videos you put together. Cheers.
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.
A micro expansion vessel then... ? 👍👍
Man you are a real trooper ., also really authentic get your thumb fixed
I sure that every customer that you happen to work will probably be very well pleased with the type of professional services that you give them. So just keep doing positive things, 🙏 and thanks for sharing!
Well Done, Kris ! You had suspected that the hose was a possible weak point on installation and had the good sense to order a more substantial replacement. A fantastic hydro installation you’ve done there! God bless.
it begs the question of putting in a water level detector to shutdown and alert customer of potential leak or water ingress in the room! Great turn around on the fix which is the main thing!
That’s a great idea
Things happen Kris, and im sure it will down the road with other jobs....
Its how you deal with them, and can see you have dealt with it very promptly and in a professional manner, if ever i needed a Hydro system you'd be the first id call.
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
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.
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.
I noticed that and was about to comment the same thing.
Such impressive work Kris, your knowledge of these systems blows me away. If only you were in the US and could install one for all your American fans. Haha
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.
What I have always liked about your videos us you are not afraid to show the stuff that goes wrong. Top video as always
Things I'd fix, at least for the next revision:
- mount plug *much* higher (in the first place)
- drain, min capacity: max flow (as happened right then it will happen again). Maybe mount turbine higher if feasible, add flow guide to facilitate drainage.
Hope your thumb is OK.
All the best to you both.
Well done on the fix mate, I remembered you saying you weren't happy about that pipe.
It's a measure of integrity when people show both success and failiures. It's what makes it all the more interesting to watch.
As an electronics engineer of 35 yrs practice, I make more mistakes every day than Kris seems to make in a whole project.
Very impressed with the mythology --- Calculate Three times, Measure Twice, and cut once !!
Love your videos! I would recommend fitting the plug / socket the other way around. female socket on the turbine, male plug on the cable to controller. would be safer in the event of the turbine accidentally becoming unplugged while in motion.
en.m.wikipedia.org/wiki/PowerCon would provide the ideal shrouded connection method here.
You should claim out time back from the suppler of the pipe. It didn't do what it said on the tin. You have the pressure readings so you can prove the pressure and it wasn't a water hammer.
Good job happy customer in the end.
Should name and shame the company too. Shoddy product should always be called out.
I'm tempted to agree.
This was not Kris's problem really. The hose was not 'as sold' ?
@@Supadrumma441 He should definitely have a word.
@@VFRrider I would have to have a word with them even more so if they were supplying lots of things.
Really do appreciate your work and honesty in videos a true credit to your self and your hydro company. Great watching your progress, good luck!
Morning Kris. I’m absolutely loving this channel 👍🏻 Well done you for the pipe fix 😀 The way you explained things is really interesting and understandable 👏🏻
Sorry about your thumb. Glad to see the new hose has a smooth inside. The ridges on the inside of the old hose can't be good for smooth water flow.
Oh no! Good prediction on that dodgy hose.
Awesome well done Kris if only other people providing utilities were so honest !
This is when quality of planning is great. That connection you set up made it so you COULD fix it. Nice. (fyi - when I saw the thumbnail, my first reaction was OH NOES!!!)
The new one looks much better
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...
Well done , you warned everyone, I am sure your client is delighted with the job. great chanel thank you for letting us watch.🇮🇪☘️👏👏👏👏
really enjoyed this series kris, thanks for sharing the problems and solutions. new pipe looks sweet
One of my favorite TH-camrs commenting on one of my other favorite TH-camrs. Love both of your channels, keep up the great work and thank you for sharing your projects with us.
Good choice with that pipe! (apart from skewering yourself xD ) I do recommand to put some paint on your welds. The surface rust can become a problem in the long run even though its stainless steel. Love the videos as always!
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.
@@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 ^^'
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
Just enjoined watching your North Wales 1.5 Kw Hydroelectric System series (1-6 and this PS). Very interesting to see a system like this customized being made. Even the pipe burst (and predicting it) shows your craftmanship. Impressive, thanks for sharing 👍😜
I think you did everything right by the customer; finished the original work as quickly as possible with the original materials ordered. Inspected your materials and notified them that part of it wasn't up to your own spec. Then were pro actively working to replace it even before it went. You gave them fair warning and an opportunity to not use it if they didn't want that small risk.
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.
A good update Kris and proof, if proof were needed, that prototypes or first builds can always be improved on by experience,
For the potential knockers you addressed at the end ..... If you think it's easy then you try doing it.
Ice had my own water supply issues this week and my system is nowhere near as complex but equally frustrating because of poor quality new parts.
Thanks for taking us along. Its all valuable knowledge, even though it's way over my head. I love it.
Thanks for the transparency, Kris. Failures are the manner in which engineered products are fine-tuned anyhow. God bless.
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.
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.
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
I’m a regular guy that lives in Colorado. I have flowing water on my property. I’ve been interested in electric production as well as a fan coil unit. Your work is incredible. Nice work
Great job 👏 you sorted it and it’s spot on ..can’t believe the pipe let you down but turning up and sorting it out quickly like that is awesome credit to you and your business
Nice fix. But as an electrican i shiver seeing that connetor so close to generator, just move it up to 6 feet above to avoid water ingress. Also the generator side should have the female connector or even better, just a junctionbox. 👍
Doing work like this for paying clients that does not meet regs is criminal.
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?
Hi Kris, On every job there is something to be learned. The company that supplied the inadequate pipe should be informed of it's failure and you should be reimbursed.
There is no fault in your abilities nor in you professional attitude. We rely on others to to make a perfect product that is guaranteed for the job that it is made for so the failure is theirs and not yours.
I believe in you Kris so don't beat yourself up about it.
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.
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.
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!
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.
@@KrisHarbour ahhhhh!!! Brilliant. Thank you for teaching us 🙏.
Looking forward to future videos.
Ahh sorry this happened to you, at least you seen it coming way before, which means you're precise. As rated so much higher while still failing, that burst was clearly obvious a fault to the manufactured piece. Not anyone involved. But it was great seeing your replace it, and awesome seeing it all working by the end. :D
Looks absolutely amazing! I can't wait to see you apply everything you learned on this one to your home system!
good to see you. abundance your way 🙏🏼
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
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.
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.
Your intuition is brilliant Kris! Well done, keep being true to yourself. 💕
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.
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.
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.
using SY cable is not rated for that kind of application to take the power off the generator its not corrosion resistant
Excellent video, Kris! Full and direct (your repairs and analysis 😉) Good work, man! Thank you!
Good to see you stand behind your work and do right by it. Enjoying your content as always!
