The PTFE tip about wrapping round a smaller spool is brilliant!!! Thanks. I really enjoy your videos.

It seems like I have something new to fix in this house every week! I hope everyone has a great Sunday 😉

Hi, great video, followed your instructions, I didn’t have a sewing machine spool, but I cut off the top of a pencil and wrapped the PFE tape round it. I also like the idea of using blue roll to identify if the leak was fixed.

It's these little nuggets that make your channel so useful. Thanks

By far a better fix is with hemp and paste, you don’t even need to de pressurise the system. We fitted a new Bosch 30Cdi to a working men’s club in Hemsworth, replacing an old conventional non- pressurised system. When we filled and pressurised the Bosch, 50% of the compression joints Leaked. Slack the back nut off and lower it down the pipe, it will dribble slightly but no gushing. Press gas paste up into the chrome fitting, pulling down slightly on the copper to pull the olive away. Then wrap in hemp and paste, allow the copper pipe back up to seat the olive and nip the fitting up. This worked first time every time, and with the heat passing through the fitting it will set hard and solid. Completed in 90 seconds per fitting.

Thanks for video and tips 👍👍. It's never ending sometimes with houses. It's not just you every time I plan on going somewhere I always end up doing a job😬. Such is life 👍👍

Great, "get me out of trouble video" and hopefully a permanent fix sometimes its just about having courage to have a go .....hope you are feeling well in yourself after your recent problems

Couldn't agree more with the last comment regarding the sewing machine spool. When I think of how much tape I've messed up trying to wind it in a confined space.

Hi I had a similar problem a few years ago and had to drain the system to get at the leak. While I had the system drain down, I fitted in line stop valves to all the radiators (both sides) so if I have a problem now I can easily isolate any radiator, this has been useful and makes it a doddle to wallpaper or tile behind a radiator.

My mam has been asking me to fix this for 3years Thanks man

A great tip i used to do the same with good old hemp and boswhite.and a wedge down the side of the pipe just in case it dropped through the floorboards, cheers.

At least in my house the pipework under the floorboards are free floating so when you into the nut there is the risk the feed pipe would drop out under the weight of the pipe and water in said pipe. It might be an idea to lightly clamp the pipe with an adjustable spanner or something first to reduce the risk of the pipe dropping out. Also for gravity feed systems maybe shut off the header tank out feed.

Good video, i quite like the loctite thread sealing cord for stuff like this.

Fantastic video. Exactly the same problem as I had!!!

Useful tips, thanks for the video. I have a leak under my kitchen sink to fix today 😖

that was top tip about the ptf and I toataly agree that system hasn't put any enhbiter for a long time enjoyed the video

Hope you are on the mend, great tip especially using the sewing bobbin 👍🏻. The trouble with pressurised systems is that they tend to find weak points on systems that were installed some years ago. My lad has an old ½” drain cock that just continues to weep and is near to a very old radiator that needs replacing. So delaying to the summer. I’d contemplate installing a Magnaclease or something similar, you should be able to install that yourself and would aid having that system power flushed. BUT I could be wrong. Happy Sunday. 😊

Bleeding hell! (no pun intended) that system desperately needs some inhibitor in there! Nice video as usual btw.

I always enjoy watching your videos and your common sense approach of your repairs,thank you for sharing....cheers!

Thanks as I sort the leakage as you guided. 👍🏻

Thanks very much. That was exactly what I was looking for.

Another brilliant video

That spool idea is genius!

Well done. Really good thought.

This gezza is simply a legend 🤔🧐💯

Informative as ever.. we are all leccy here so not much help .. still good to watch while aving a brew :)

Looks like the system is ready for an oil change mate. Haha.

I have started using copper olives rather than brass. They don’t require massive torque to tighten and seal. In theory they would work hardened on multi changes of tails or valves but seen to seal much easier on original install

I've got a leak in exact same spot! Great video. Edit: I need me a second spanner...

Thank you so much it worked!

Time to slap on a magna clean filter keep all the nasties out the system! Squeaky bum time when you loosen the rad valves or attempt to nip them up when full! I’ve had one go on me! Not great haha! Keep the videos coming mate! Always watched your channel!

Thanks :-) Just what I needed.

Wrapping the PTFE around the end of a pen is good.

Repair done. Now eying the repair nervously for further leaking

Tnks so much I understand know tnks

talking of flushing out a system how often should one do it with a combination boiler ? every 3 years maybe ? and how should it be done ? turn the boiler off and drain the system from the radiator furthest away ?and then refill the boiler with the loop hose ?( luckily mine is perm fixed with a valve tap )

Good Tip chaz 👍

How come you didn't use Liquid Teflon. It's a lot easier especially in a tight spot

Nice video as usual. That central heating really needs a flush. I have heard the new combi boilers don’t really like messy systems as it may clog some sort of screen filters.

Brilliant but how do I do the exact same to a downstairs radiator 😬 I’m a complete novice, not sure if I have to close down the whole system or not! Thanks

The pipe leading to the rad isn't completely straight. Could this be a cause or contributer to the leak? Or leaking in general? Also do you have a magnetic filter on your central heating system? Just curious as water was murky. Great tip re: PTFE tape.

Off tape didn’t work for me last time I tried it so I ended up cutting off the olive and replacing it with a new one and that’s twice I’ve tried to do it on a job and it failed due to compression on the property I was in at the time ok

using sewing spool was sooooooo ingenious. Thanks for the tips ;)

A useful video; I don't have that type of heating, but it was interesting to watch the procedure. I liked the genius tip about putting the PTFE tape on a sewing bobbin to make it easier to use in constricted areas. The problem, though, is not everyone has a spare bobbin laying around unless they're married and their wife sews. Not that many women sew here in America, anymore; it's become a lost art. Overall, the only thing I would have done differently is use a combination wrench to remove/reinstall the compression nut. I don't like using adjustable wrenches as they can slip or open up, rounding-over a fastener. Thanks for sharing this with us.

brilliant video.....does the leak sometimes seal itself with all the crud in the pipework?

WOW! THANKS VERY EASY.

I would ALWAYS pull the carpet back before attempting these jobs, I also AWAYS use my aqua-vac (Charles)! I do however like the sewing spool idea!

You can use a short pencil and wrap tape around tip and apply in tight space.

How hot would the water be coming out of the heater

I have never seen a system as dirty as that ,it definitely needs a cleaner added and let it run for a while then filled and flushed again until it clear then a couple of bottles of sentinel 100,as for using a spool to put the ptfe use a pencil or use a paste.

Hadn’t thought of this, handy if you can’t drain the system down for whatever reason. Have you done a video on pipe freezing if you had to fix a leak on a mains pipe but couldn’t find or be able to shut the water off at the stopcock?

Good old PTFE ! Cheap and works well. The worst thing you can do with microbore is overtightening it.👍

How do you put inhibitor in?

Hi, i have just drained my radiator to tighten the tail end as it was leaking. Now the boiler pressure wont go up. I have tried repressurising it and it wont go up at all. Its at 0. Please help.

Brilliant

What do you prefer PTFE or LOCKTIGHT TAPE ?

I would just add to note how many turns it takes to close the locking valve down. Then, after repair, open it by the same number of turns. If the system has been balanced you preserve the status quo.

I'm a DIY dullit but after watching this I might just give it a try.

On my first try I found that the strong water spray made it impossible to wind the tape in the righ tplace. The solution was to tie the tape round the pipe at the start, which kept it in place and made it easy to wind.

Wow oil filled rads! Good informative video though. 👍

is that a bruise on your right arm?

Use a pair of mole grips to gently grip the pipe under the towel, if the pipe suddenly drops out of the valve you’ll get a lot of water especially in an open vent system

What is Central Eating?

Problem is my leak is seeping from the bottom of the radiator pipe under the ground it's coming up from where the pipe goes into the ground

Thanks for this. I watch all your videos and appreciate the time and effort you put in. I have a pressurised system and our leak is coming from the gland packing nut (it leaks when the thermostatic valve is opened). My understanding is I can close the thermostatic valve, loosen that valve packing nut, and put PTFE tape under it to solve the issue. I don’t know if I need to drain down the system though?

I'm going to tackle this job today, its been Leakey for years and i am scared to touch it. But here goes 😮

Had this happen a lot in a previous house that was fitted with micro-bore pipe. Every time you did the vacuuming, you would know a pipe and it would start leaking. I know copper is not cheap, but it is the worst idea when it comes to heating systems....

Who's put engine oil in the heating system ?

System filter and a system flush would benefit that system by the looks of it.👍🤓👍🍰

If you were to have a leak Downstairs would you have to drain the entire system

The sump oil I changed out of my van was cleaner than the stuff in your rads.

I had my plumber come and fit a spirotech deaerator to my system. My system already has inhibitor and a magnetic filter, but every cleanout of the magnetic filter resulted in ink black water being collected. Plumber says that oxygen in the system is responsible for 80% of corrosion, but the remaining 20% is galvanic corrosion which can be caused by ph being out of balance. In theory the inhibitor should take care of it, but it’s job seems to be a lot easier when there no oxygen in the water.

You've hit crude oil on that rad get a pump on it to BP - good video though thanks for ya time making it

Isn’t it worth shutting off all the rads in the house before you start just in the event that you dislodge the pipe you’re working on? That way all you would lose is the water in the pipework and not the rads

how effecient are these things , im assuming the water is heated using electricity, do they have a big impact on electricity consumption is what im realy asking i guess. i do like evacuted tube water heating , works even in cold climates no electricity required.

supper

Looks easy but if I did it I would no doubt flood the village ;) my mantra...if it can go wrong it will go wrong :D

its a bastard when its a flexifit behind the radiator into wall fitting

Just a quick question mate . I noticed you emptied a little water out via the bleed nipple .if you’re isolating the rad anyway why would this help ? Great video btw👍

I found this video very radiating. Lol. 👍

If you didn't have a sewing machine spool, I've seen a plumber just wrap his finger with the tape and apply it that way, although it could be awkward too and you'd need to used to it.

Good vid' but instead of PTFE try Loctite 55 next time..👍🏻

Good video that's black gold coming out of the radiation😃

I was wondering why my boiler lost its pressure

Good vid but water like that I would give the system a treat and do a full drain down

Valve is totally stuck. Fear I could make things considerably worse.

£180 job laughing at the end plumber 20mintues work 😂

Free guinness from the radiator don’t mind if i do

The problem I'd have is finding a little sewing machine spool lol !!

Very unusual to get a sealed system with contaminated water at the top of the radiator .Considering you had the system power flushed once , you may have something else going on somewhere . Have you ever had to top up the system regularly because of a leak ,Introducing fresh water regularly will cause corrosion in the system . Are you bleeding the radiators regularly,You should not need to in a sealed system If you are it may not be air but hydrogen gas,their is a smell from it if it is but it will burn as well so be careful when you are checking . Closing down the automatic air vent on the boiler has the effect of holding the water in the system when the system is at zero pressure . ( Only gas Safe Registered people should work on boilers ) .

Tohle mi moc smysl nedává. Bylo to málo utáhnuté.

I call that being mummified

That's where Pepsi comes from.

Fuck sake, that’s like oil

Looks like microbore. Yikes!
