Hydroelectric Turbine Pipe Burst Fail 

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

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...

We love everything Kris does! 😂

You come across as good guy

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.

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...

NASA have....you called it, thank god no astoanaughts were trapped in that valley pod

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.

Think a maccy D straw would done a better job lol..

That is the best comment ever😂😂😂😂😂😂😂

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?

A micro expansion vessel then... ? 👍👍

That’s a great idea

I noticed that and was about to comment the same thing.

en.m.wikipedia.org/wiki/PowerCon would provide the ideal shrouded connection method here.

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.

One of my favorite RU-vidrs commenting on one of my other favorite RU-vidrs. Love both of your channels, keep up the great work and thank you for sharing your projects with us.

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 ^^'

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

Doing work like this for paying clients that does not meet regs is criminal.

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.

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.

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.
