Now repair the Nordstream 1 & 2 lines.
Whilst holding your breath.
no thank you, we dont need it
Was almost faced with this very situation on Monday: putting 4"x2" studding around a wall (later to be filled with 4" Kingspan) asked my mate where the underfloor heating pipes ran. "150 mil from the wall, so you're ok," he said. So I started drilling, keeping the holes as close to the wall as possible. Got three holes done before he shouted "Oh no - not there!" And he'd forgotten to mention that in one place, the 22mm pipes to the manifold actually ran directly under the studding. I had to cut a section of the soleplate out and dig out a section of the screed, otherwise he wouldn't have slept for a month. Thankfully, when I got to the bottom of the drill hole, the pipe was nowhere in sight. I can see big problems with underfloor heating in the future...
That was really interesting. Repairing something can be a lot harder than installing it from scratch. Also that's a lot of useful info on PEX and those fittings. Cheers!
Glad you liked it!
@@SkillBuilder It's amazing how much they tell you on on the Level 2 City and Guilds, but they can't get everything in. And there's always more to learn! Your channel is really generous in sharing the nitty gritty stuff!
Plus just brilliant for non students anyway.
Really great! Thank you!
Repairing the leak is an awkward job. Getting to the pipe & making good afterwards can be VERY costly. I had a customer last year who had underfloor heating under a very nice marble floor. We had to dig up the floor & dig 6" down through screed. The customer had no repair tiles & the company that supplied them had gone bust. We agreed to replace the whole floor in a big hallway. Total cost of repair was over £17,000. We guaranteed the repair for 5 years. Needless to say; we did make sure it no longer leaked.
I do like the idea of UFH, but it just becomes another thing buried and hard to access in the event of failure. A rad failing is worst case a few hundred to repair/replace, time to investigate isn't long either. May be UFH at first floor is less costly to repair, but still miles from conventional heating 🙄
Insurance job for sure
@@SkillBuilder For sure, probably a good job NOT to DIY
@@SkillBuilder The customer did claim on his house insurance, yet only received half the amount of the whole job price.
I guess that's a subject for another video.
@@Gordon..From memory, the insurers only paid for an 8'x2' repair, regardless of whether it completely matched the rest of the floor. So I'm guessing they paid around £6,000 - £7,000 & the customer paid the rest. Thankfully, insurance isn't my department.
Thanks Roger, as you said, not an easy job!
You Rock Roger
Thanks for the demonstration🇨🇦
I had new build library back 2008, the door automation contractor got a drawing that had the UFH loops omitted, I had 6-8 of these to do with screw holes. Ended up lift the entire screed, in the zone 6×6m putting new pex alu pex in with these couplers, then Top Cem screeded. Great job, 14 years on and no reported leaks since. Smaller repairs post create works very well as 2m2 screed. Just used S3 tile adhesive after.
It seems you did well. I hate drilling near pipes, I use a thermal imaging camer but it is still a nervous moment.
Top man 👏
I've done this recently with a water pipe, DN32. It was hell!
As always, great educational video.
I think when I come to laying my own under-floor heating, I'll ensure I have sufficient spare pipe, a rounder, a couple of connectors, and a cutter as well, just in case!
You mentioned that the pipe had aluminum within, are there superior products on the market, if so which type of piping would you fit in your own home?
Regards
Robert
The alupex pipe is the best and it lays flat but, to be honest any pex pipe is good for 50 years.
The content was very good.🥰
Tricky game 👍
since this video is only a few days old i would like to ask you a question i´ve been raising myself about rockwool insulated sandwichpanels. The climate i live in varies a lot between -3 and plus 5 My main questions is: does the rockwool gets humid from condensation if the panel has breathing holes? in one case open holes inside metal or alu sheet and the other to the outside(bottom top ). The similar question for lets say a perfectly sealed of sandwichpanel. Does any water accumulate in there? off course i´m not talking about rain able to enter. I´m very curious. Roof, wall and floor. Great channel. best regards,
-3 to +5, I'd move.
Can you screed over those connectors? Sorry, don’t know if you mentioned it in the video.
Yes but I would wrap it with tape.
I was going to ask the same question. Would u gaffer tape or self amalgam tape the connector before screeding. Makes sense to do it.
Once had to repair some brand new ufh in a new golf club, club house where the installers of the seating in the changing rooms was being installed and had ,for some reason,drilled the floor and punctured the pipe work. After chopping out the affected area I thought it would be an easy repair just by cutting the pipe at the puncture and rejoining with a connector but a surprise was yet to come. After cutting the pipe I noticed something on the blade I had used to cut, after checking it out I realised it was SILICONE sealant. Fortunately the pipe was a clear pipe and on inspection could see that the silicone had traversed the pipe around 150mm either side of the puncture. Needless to say that section had to be cut out and totally replaced. As it the club house was in the process of being second fixed the only floor to be replaced was the overscreed before the Amtico type floor covering went down. Could have been an extremely costly repair.

So are you saying that they drilled through the pipe and thought they would squirt some silicone sealant in the hole to seal it?
@@SkillBuilder exactly that
You wouldn't expect leaks as you should not have any covered joints from new installation. When my mate fitted his, he pressurised it above working pressure, not only to test for leaks but to ensure that when the screed was applied and set, there was ènough room for the pipe to expand under working pressure and thermal conditions. (The high test pressure was not released until the screed was set)
I have done the self same thing, pump up to 6 bar and then drop it back to 3 bar, lay the screed and watch the pressure guage rise to 4 bar or more as he heat from the curing screed warms up the water in the pipe.
@@SkillBuilder degree in common sense from the university of life!
Off topic question: I live in Canada and have watched a few vids from England(GB) in heating etc. I have noticed that there are a lot of water/steam boilers there. Are there many electric baseboard heating systems used there? A great deal of Canada is gas heat with electric baseboard heating coming in a distant second - so far anyway. Almost forgot that Heat Pumps are on their way up the ladder, although from what I understand, Heat Pumps require a sealed home to work properly - New construction mostly. Expensive renos otherwise. Thanks 👍
We have harldy any electric base board heaters. I have installed them but the electricity prices are very high here.
@@SkillBuilder Thanks
Roger, great video but how do you find a leak under a tiled floor, if the grout lines are not damp presumably a thermal imaging camera?
As I said, it is very rare for underfloor heating to leak unless it is damaged. If you drill through it you usually know about it . If there is a leak under tiles the grout lines will darken but using thermal imaging is always a good idea because you will see a patch.
Viega smartpress !!!
What is the typical working pressure in the pipe
1.5 bar
what's the size of the inner diameter, and are both the same?
The inners vary slightly according to the type but it is usually written on the pipe so look at the manifold end
Interesting! Our floors are heated from the sun. It works great! 🌞🏜️
Thank you for the idea. How does that work in the winter ?
We have big south facing windows that let the sun and heat in during the winter. The roof overhang is such that we don't get sun coming in during the summer. We just moved in, it's working wonderfully! We have been down into the teens at night, and the coldest it's been inside is 69° F. The windows are our only heat. We do have an earthen floor, so it's a little like being outside but much nicer. 😄
@@RedandAprilOff-Grid so no floor heating. That is a bummer.
@@mleys3248 It works awesome in the desert with a well insulated house. We are heating our home with only the sun. The earth floor is absorbing the heat and radiating it out at night. It's getting down into the 40°s at night in the camp trail we were living in.🌞
Hi Dale from Annabel and Guy, we got 30..
Ufh. ....eyes glazing over....for the whole concept.
It is great, once you have it you don't go back and neither does the cat.
Вы не докрутили трубу и фитинг вылетел. Такой ремонт приведет к большой проблеме затопления
Ct1 magic seal.
You are joking of course
Now pls tell us how to find a leak on ufh
It is very unlikely that your pipe will ever leak, it is just too good but you may get damage where somebody drills through in which case you will see it
Does Roger realise that he probably should have fed the nut and olive over the pipe ends before using the flaring tool or am I missing something?
Entertaining and informative as always.
Hi Nick
I would do that if it had been a flaring tool, they have fittings that actually work like that but this is a re-rounding tool and it should never expand the pipe end because they pipe seals internally on those 'O' rings. If you use the tool and can't get the nut onto the pipe you have done something wrong.
@@SkillBuilder
Obviously I got the wrong end of the stick, so to speak.
plumber advice here. If you see a plumber fixing such a leak with these kind of fittings tell him to leave. anything that is buried has to be with a press fitting, the fittings used in this video are ok if in a place where you get access to it because they can leak, it is not difficult at all to over or under tighten and have a leak over time. So a big no no to put such fittings in places where they can be buried.
This happened on our house in the end the plumber has to take the whole line of pipe out and relay as the leak never stopped
@@pburgess4727 ouch, sorry to hear that
Rehau sell this fitting and it is a repair coupling. I have never had any trouble with them but I would agree that it is better to crimp. £1,000 for a crimp machine is a great investment if you are a plumber.
@@SkillBuilder in my country Romania, it is illegal to bury such fittings, crimped ones no problem, but the ones with the nut are not good. If the house has leaking problems and the insurance company finds one of those to be the problem, they are going to rip the plumber a new asshole
@@Gordon.. sadly not many, but on big projects where there is a lot of money at stake most people are careful to obide, but one can follow the low and still do a bad job. I worked in England as well and it may be just my personal experience but I've seen a lot of terrible jobs there. Very impressive in electrical installations but a lot of shifty plumbing.
First you have to find the leak. Which is the hardest part.
Very unlikely there will be a leak unless you put a hole in it, in which case you will know.
@@SkillBuilder Things do go bad.
It wasn't found til decades later, that those cheap plastic pipes break down over time.
