When it rains, dont go in drains. 

Thanks Marcus for the adventure. Check out his video and channel here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bvMeZLtvf4I.html 🚧Ok disclaimer/warning. Obviously dont go in these places if it even remotely looks like rain. Take a gas meter have an escape plan or better still dont go in. As someone once said to me "you dont realise its gone wrong till it goes wrong". This shit happens fast. Use your brains and dont let the ego take over. take care 🚧

Disclamer: Anyone who goes past this on Five Weirs Walk and has noticed this culvert outfall, please do NOT go up, it is very dangerous, wet or dry weather. Thanks.

Martin, Marcus. Thanks for bring back the memories. How things have changed. I was born in 1947 on Limpsfield Rd. Brightside not a stones throw away from where you entered the Carbrook. We called the walkway the Dyke side. It was a short cut from Brightside bridge to Attercliffe Common where the movie theatres were. Hard to image now but back in the 50s and 60s the whole area was factories churning out stuff along with unbelievable amounts of pollution. The River Don was an absolute shit hole. It stank to high heaven. Nothing absolutely nothing lived in it or anywhere near it. If you were unfortunate enough to fall in you were dead. As a child walking down there at night even though I was with M & D it terrified me although I never let on. I left the area in the mid sixties for the better suburbs and in 1970 escaped to the Colonies so missing the close down of all those factories and the cleaning up of the Don. I laughed out loud when I saw the fish stairs by the weir. When I was a kid nobody in living memory had seen any fish in the river and possible a 100 years previous to that. Just think where all that polluted water finished up. No wonder the seas are so polluted. Disgusting really. Thanks again for taking us there.

Wow Martin that has to be one of the longest and scariest culverts you've been in no wonder you had to keep an eye on the weather. I love the old brickwork and architecture of these places so much hidden history right under your feet which the everyday person wouldn't even know about. Marcus doesn't leave any stone unturned that's for sure thanks Marcus and Martin for taking us this adventure that we wouldn't see without you guys. Stay safe guys.

I'm so glad there are people like you and Marcus who like to explore underground. I enjoy the vlogs, but the entire time I ask myself, "Why???"

You both make great exploring partners! That drain system is fascinating! Especially the architecture and brick work! Thanks Martin and Marcus!

Scares me just watching, but I can't stop watching. Excellent video, stay safe

I live in New Mexico on the border of the US and Mexico. You can not get further away from Sheffield than that and I love these videos! Your tunnel and water explorations are good history lessons and so interesting.

Loved this although I got back ache just watching 😂 Marcus is a top lad 👍🏻

Martin amd Marcus I've just spent 35 mins of company time watching this and not servicing a boiler .....it was 35 minutes well spent ...well done to both on a 1st class visit and film x

Master and apprentice. I love the subterranean videos, so much work went to building those tunnels. It’s a shame only a few will ever get to appreciate them in person. Thanks for taking us along.

Always been fascinated with drains and sewers. I love these videos Martin. Thanks mate.

Very interesting, that would kill my back and knees in there, glad you guys went in, thanks.

I've jumped out of planes when I was in my parachuting phase. I've jumped off 1,800 ft high cliffs when I was in my hang-gliding phase. I've bungee jumped and white water rafted, done yacht deliveries 100's of miles out at sea and flown a home-built aircraft on my own across the North Sea to the continent. But there is NO WAY, you would get me in those tunnels.

the title and warning 'when it rains, don't go in drains' is very good. makes me think of this video on YT that came out a couple of years ago? it was again, some tunnel and drain explorers (forgot the channel name) and it was all on film - they all nearly died/drowned, water levels rising quickly, no where to go, dark room with a very strong raging current being sucked into a massive pipe further down, utterly terrifying! Luckily they managed to find a manhole to get out of!

Love the vids Martin, they're always very well produced, informative and most of all they're very enjoyable to watch, you also seem to have great chemistry with the other lads and its obviously you are all good mates who enjoy what you do and I always look forward to Sunday evenings watching your vids with a nice brew 🙂🙂

Thanks yet again for another joint adventure, always glad to see Marcus joining you for those extra tight parts of the culvert! I must say, this is probably one of the longest, most intricate culverts you've explored, definitely worth all the leg pain! Those numerous chamber junctions were just amazing, and even though it's not Victorian, I think we can all appreciate the quality and beauty of that brickwork and how well it held up all these years! I think the biggest thing for me is that penstock covering the original route. Makes one wonder why they went to the trouble of making a new route even if the old one appears to be perfectly servicable. But still, I'm so glad you were able to get a peek under it to see that it does go on! Would be neat to crank it open from the top to have a look, without having to go through all that stagnant water on the other end. I do always wonder whether there is some city authority of some kind who have detailed maps about these structures, including that "very complicated" relief culvert at 27:53 and where it might lead. Once again, thank you so much for not only making this content but sharing it with us lot. EDIT: Ah, now that I've seen Marcus' vid, I do realize that the relief culvert joins back up with the main one at a later point. x)

And don't go in drains if it rains and make sure post 10 isn't clearing drains or culverts upstream.

I really enjoy your channel. You explain things so very well. I'm from the States, but still really enjoy learning/seeing this stuff. Thank you. Can you imagine how the land would look without man interfering with everything ? All the brooks, rivers etc that they have changed course, damned up, etc. Thank you for sharing all this with us, but please take care of yourself. It's truly not worth putting yourself through so much pain during and when you are done doing it all.

Love your work and love how the young Marcus has the passion for this too.

The amount of times I've walked past that culvert on the Don and have been tempted to give it a go... I found the old outfall when checking out the railway bridge once, wondered what I was for and now I know! Love seeing you around my area! Great work as always Martin!

I find these drain culvert exploring videos fascinating Martin, I know they are not really you thing as it can be unpredictable what you will be faced with but I’ve been obsessed with drains and combined sewers for ages!! What a good video!

Thanks Martin and Marcus these types of videos. I'm always curious about these places, I certainly won't be going down any of them. Look forward to seeing more 👏🙂🚴

Superb filming and commentaries. Scary stuff Thanks guys tough assignment. Keep safe warm dry and virus free both.

What an adventure here! Among the many interesting sights there were two moments that really caught my imagination. One was at 9:11 with the slow-motion water and the other was at 17:06, seeing Marcus emerge from the tunnel. The music and images were chillingly matched. Great cinematography overall in this one!

Thanks for uploading this. Your work is always excellent quality and I enjoy watching each video that you upload! - Robert

As ever, beautifully put together and presented. Really fascinating, this world under the streets.. All I can say is rather you than me!! Nice one Martin and Maestro Marcus. 🌟🌟👍

I love the idea of walking over a storm drain and seeing two guys drinking coffee/tea. If this were the US i wouldn't even question.

Thanks Martin another great adventure , yes pays to make sure your safety is paramount before under taking these explores , but marvellous to see such engineering under our feet that we never see or even know about done by blokes long forgotten in history who haven't had the credit for the great works they have done.

Best thing I've watched on RU-vid for years

pretty cool, was fun to watch, i love your history vids, Marcus is a cool lad a great duo on your latest expedition awesome lads. well done.

Hi Martin and Marcus, for the explorer Thanks for the explorer through the Carr Brook. I'm glad you're doing this instead of me. I love the brick work. I only had been in one storm Drain growing up, but we never gone back a mile before it was to tight. You would go through anything for pastries I hade both knees replaced and I could not do that. Thanks again for another wonderful video.

I never tire of watching this, great to see Marcus show you Sheffield!

wow - I'd be quite frightened in there - with a good instructor like Marcus you'd be ok but I'd still be worried.... great videoing guys!

Your very brave, what an adventure, and good on you true Yorkshire men for being safe. Great video

I do love a good brick chamber! Thanks for bringing us along for the journey 🧱🕳

Well done Martin for keeping up with the young lean drain machine!

Places you and Marcus go to show us, I don't think I could ever go down these places even with a guide. Thanks for another there interesting video

Another awesome vid Mart, You both did well going through all that! Great brick work through out too!

The things i watch on you tube !!! I couldn't go down there, I would have a panic attack !! I came across your video by accident, but enjoyed it. It's facinating to see what goes on underground.

Marcus seems to be testing your culvert exploring skills, I felt the leg strain and aching back. As usual there's a wealth of cracking architectural history under our feet, thanks for the journey. Good H&S advice👍👍👍

Found this hard to watch, but, I'm not a Yorkshireman. Scary, fascinating, adventurous and a valuable historical record. Passionate reporting and attention to detail should be your motto. Well done M & M. Great collab'

Wow Martin, I love that tunnel walk footage, but doubt I could manage it with my claustrophobia. Edit: Respect to young Marcus & his knowledge.

Wow, to say your just walking through a drain, that was entertaining. I held my breath at times. Like you say, all could change in heartbeat. If they did test on them overflow doors or anything else like that, you could be in awkward situation. But I guess that’s all the adventure of it. Thanks, love your videos and I agree with a previous comment, you both make a good team, there’s a certain humour to you both. I’m a Sheffield’er myself, but I prefer to use the footpaths and roads, but nice to see what’s underfoot.

Loved that. It was just so interesting. Next time I go to Sheffield (brilliant city), I'm going to spend the entire time staring at the floor. This channel just gets better and better.

I could see your caution at times during this adventure and you were so right. It was amazing to see the complexity of the engineering over the years, but quite unsettling to watch. As the ‘older dog’ on the day, your sense of preservation is much better developed than that of the amazing Marcus, and probably just as well that’s the case. You were both great and it made for a heart in mouth, suspenseful video. But please take care out there, even when lured by apple tarts! 👍⭐️

I did feel for you Martin. That looked like torture and yet another fabulous video for your pains. Thank you.

1:15 Those 2 passersby swiftly gave that idea a miss. Walk on by!

😂 ....the video started out with an ad for unclogging drains.... .....nice.

Just to let u know Martin when u see water spurting out of the gaps it means somewhere the culvert has failed and water travels underneath the culvert,until it finds a way out and this was the point were u saw the 2 water like jets sprinkling out.

_Thanks for the Journey Back in Time._ Too bad there aren't any maker marks on the bricks. Here in Chicago our old creeks and Brooks that were reinstalled under ground are big enough to take our rafts through from right off Des Plaines and Chicago River.

Absolutely awesome footage i go past this on a daily basis and always wondered what it was , you guys have a balls of steel for going in there hats of to you all, keep up the good work 👏 🙌 👍

Ah, so envious. Fantastic walk.

Its amazing how many water ways get buried, where I live on the side of valley there are many culverts which feed down to the beck/small river. Which used to supply many mills along its course to the centre and through Keighley. Apparently the center of town was either very boggy or a lake though I havnt done any research to verify this. suffice to say the 40 years Ive lived here you notice the same patchs of road subsiding due to what i imagine to be bad/ or very deep drainage. Also cant wait to see you pass 100k😀

Brilliant video Martin yet again thanks

Another belter Martin. It's good to see you and Marcus again. The culverts were beyond me but you guys managed brilliantly AND there wasn't a wet arse in sight. Time for a brew...

Hope to see more of Marcus in future explorations. 🌈

I used to go into places like this for work, couple of things I'd do different, I'd put on a caving helmet, makes it more comfortable if you are in low headroom if you relax about scuffing your head, but more importantly, I'd never put on waders without a life jacket, waders can make you float upside down and being able to pull the cord and get your face above water is kinda helpful. Nice to see you using a gas meter. A dry suit makes this so much easier too, but it's not discreet before you go underground!

Another great video 👍 fascinating underground footage. Get down the drainage system in collyhurst from the river irk the Sheffield lad would love it, you've had a little wander through some in an earlier video of yours. Cheers to you both for a great video I'm looking forward to the next one👍👍

Wow wow wow brave boys. That was so good and scary not knowing what you would cone up against. Marcus great guy. Obviously loves the fun of it. Great team and superb filming.thank you.

Appreciate you showing the location, now I know where to go if I visit Sheffield

martin i love your videos mate, never fail to amaze me 26:20 that smile when marcus mentioned apple pastries when we done this has me crying 🤣🤣 hilarious lads

Hey Martin, Love the videos. We have just had our narrow boat in the dry dock at the CRT yard in Ellsemere. When this is drained the water goes into a culvet, which could give you a nasty surprise even on the bluest day :-).

That lad looks in his element in there! Absolutely love the sections where the camera is doing that long exposure thing

When on rivers i always look at weather patterns near the start and along the entire rivers path to where i am. There can be a torrential down pour 100 miles up the river that flash floods areas past that. I learned the hard way. I was along a river fishing, and the weather was beautiful, where I was. But about 30 miles away was a storm. And all the storm run off goes to the river. Over about a 10 minute period the river rasied up about 3 ft.

Well done guys, another fantastic video 👏 👏

Another great adventure. I could not do it all my joints would seize up. Martin came close to it. Thank you both.

What a couple of brave and adventurous young men you are. Great video

A fantastic video today. Have been hospitalized for three months with Covid 19 as associate problems. Have not seen any videos. Glad to see you again, Martin. Cheers

Martin & Marcus dream team. What a great video guys Thankyou 👍🏻

What a great journey you took us on. Great Video!

I can honestly say that section you crawled was higher than most faces I crawled Martin. Not quite as wet but it still bought back memories of when I was a fit healthy lad. Still enjoyed the crawl through time ! 👍😁

Thanks for another great adventure Martin & Marcus ! Bit appropriate this seemed rather foreboding, coincides with it being Halloween time. Pretty scary being more than a mile in & under, and if you'd hit a methane pocket or the air go bad, it'd be some very bad shit. Absolutely love the old maps and "then and now" comparisons, amazing stuff.

I've been to the Carbrook Hall pub (which is now a Starbucks, I believe) a couple of times when we've been up to Sheffield (from Wolverhampton) for the World Snooker Championships. It was once known as Sheffield's most haunted pub 👻! Now I've seen the brook Carbrook Hall took its name from with my own eyes! Great video guys!

The brickwork is outstanding on these culverts once covered never to be seen again. Proper tradesmen in by gone days.

Hi Martin great vid as usual, I love the way you totally ignored the step feature thing on the right when you were heading for daylight! Marcus is a good addition to your team.

Another great video Martin, well done dude

Another great video, thanks lads ❤

Another excellent video Martin :) I always enjoy the old brickwork that you see in these places. They really were artists! And after seeing the less-than-ideal conditions at the old outflow, I thought of an idea for a new member of the team: Boatrover ;)

Very interesting, I have known Carbrook from where you finished up towards Manor Top and always wondered what happened to the brook after it disappeared beneath the, now demolished, Halfway pub. The pub was just about where you finished in the 'cage'. Many thanks for posting

Your nearly at 100k martin !! Hope your having a beer with your subscribers when that happens !!! Haha .hard work paying off for you mate it's been a pleasure watching your channel grow

Another great video Martin, I bet you would have been surprised to find the legendary Patrick Dickinson down there 😀

Too bad I wasn't with you's, looks like fun 🥳 . Just a thought. Thanks for posting it. Have a great weekend everyone

Thanks for the interesting journey.

That brickwork is stunning, look at that curve on those bricks as it flutes outward. You need Tank-cam in a lot those spots lad. Thanks for the video and stay safe.

My knees already start to hurt, only from watching your video 😉. Great video Martin 👍

Your both mad but the video was fantastic and a utter joy to watch and experience as a viewer. My favourite video of 2022 on RU-vid👍👍👍

I am not entirely sure why this was recommended to me but I am definitely not complaining :D

Great footage thank you guys

Quite a relief to se the daylight again at thd very end. Brill job lads, Bet youz were knackered!! 🥵🥵😩😩🥴🥴

Fair play to you both that’s a long old way to go! I do works in London’s sewers from time to time and can fully appreciate the pain you’ll have in your quads. Just subscribed to you both 👍 just one thing to note, if you do venture into a culvert with soft/silty ground hire yourself a Escape BA Set or as you say better still don’t go in

That was scary, but very interesting. Thanks guys.

I work in one of the units opposite and honestly never once considered what was in that pipe. Thanks for sharing!

Oh, to be young, fearless, and made of rubber again. xD Marcus's enthusiasm to just hork it down random tunnels will never not cease to amaze nor amuse me. xD

Two miles!! ,that is awesome..yep looks well dicey, if the Don swelled up..well done Martin .🏆

The work behind you in this video is wonderful.

love it, keep up the good work

To be young and agile again eh Martin 😄 Another great video where the vast majority of us wouldn't dare to tread 😁 it's amazing all these rivers and brooks that have been culverted and the work that went into it particularly all those bricks. I wonder if the original route was built by the railway company, definitely railway blue brick on the end of that disused culvert.

Good to see you using a meter and adopting a safe approach. Seen some jaw dropping stuff on other channels dicing with death.

Ive got backache just watching this LOL. Interesting tour.
