P B Plumber Finding a leak in a floor

[@johnferguson40]

What a terrific video for this non jandyman. It must haave been a nightmare for the owners but helped immensely by having someone who is a proper and trustworthy professional dealing with it.

[@JU5TAGAM3R]

I've just started my level 3 plumbing and been getting some experience with a plumber. He said to watch your vidoes and tbh I've learned so much from watching you. Love the vidoes mate keep up the great work!

[@allencowe9446]

I'm a bit late in seeing this. I had a similar issue before at a hotel. We left the heating on with all rads turned off. It made it much easier to find the leak as the boiler was at temperature so the heat escaped through the leak. We then found it with the thermal imagining camera. Great video, thanks for sharing.

[@SiKay3000]

Worked at BG for 28 years and we used fernox leak sealer. Very rarely did it make any difference what so ever. Started using ct1 miracle seal and it never failed even on systems that were losing full pressure daily. It does not block boilers including combi’s as well.

[@theCybershot123]

It worked for me more than once

[@johnread1201]

How much miracle seal did you use to plug the leaks?

[@johnread1201]

My plumber has used one bottle on two separate occasions and it’s made no difference

[@normanboyes4983]

Good video and a good example of the consequences of burying unprotected copper in concrete.

[@jennyli7749]

I had exact same problem and ended up paying for a new boiler, heating engineer took a guess at where the leak was cos new boiler was still losing pressure, and found it to be the plastic pipes under floor of the extension (he said often extensions used plastic instead of copper so more likely to leak due to degradation. He was correct! My other option was to dig the floor of top end Karndean flooring which I wouldn’t have been able to afford to re lay if random holes were to be dug all around house 🙁

[@djgaryc]

Great video. I know nothing about plumbing but was able to follow and understand the methodical approach. Very interesting 👌

[@UberAlphaSirus]

Good tips. I have some tips for you too. Dunno if that camera does it, but if you can set it to not have a dynamic/auto range and set it to manual range. set the bottom range 0c and highest range to about 80c. That will give you a consistant picture vs heat. IE your cuppa tea at 38c won't be the same bright yellow at 80c 4 seconds later pointing at a hot feed. If that makes sence. It's not always possible, but it's alot easier if a client can keep the heating off for 24 hrs before you investigate with a heat gun. this is because of heat soak. if you start with a cold pipework and structure, you can observe the spread of heat before everything has heat soaked and reached an equilibrium. Shows up well on wet materials as wet stuff conducts heat faster. But again thats why it's best to have a fixed scale on the camera, as before and after pictures and recording will look basicaly the same with auto scaling. All the best, top fella.

[@pasgas12safe58]

Sirius, very interesting mate, thanks for your logical input!!👍👍

[@frostie1970]

Heard a tip from skillbuilder. Put a cheap aftershave in the heating cct and literally sniff out the leak.

[@JakeMcNamara1]

actually thought when you had thermal camera on at the entrance it did look quite spread out. Fair play to the guy for digging it at least 🤣 great video.

yeah when i was editing it i thought it looked more spread out, it didn’t register with me at the time tho

[@BTW...]

By far the quickest, easiest and most accurate way to find leaks is by use of sonic detection methods. Small accelerometers (like microphones) are located between a pipe run and the sound of fluid passing through the leak is detected. Time delay between the 2 sensors is calculated and the leak location is determined within a few mm. Thermal imaging is all well and good, but through carpeting and concrete is highly optimistic.

[@nickgiles1991]

you would not correlate in a house... surely just listen at all available points.. correlators get confused by branches and caviation... i often use a combination of acoustic and tracer gas

[@sam.p12345]

Accelerometers and microphones are two different things. Granted, an accelerometer is likely to be minutely responsive to sound waves, but you wouldn’t use an accelerometer to detect sound.

[@davidceredig-evans8772]

Excellent video. Thanks for all the hard work you put in.

[@peterfitzpatrick7032]

Lifting the carpets before thermal imaging might have been a good idea... 🤔

[@derekmears3434]

Good work Pete.

[@sheli4239]

We can hear water movement in the pipes, sounds like a seeping toilet valve. There's no visible leak above the slab anywhere, so it's probably under the slab in our 35 year old house in Florida. We have extremely hard water and just did some bathroom mods. Shower, wall toilet and maybe we shook loose a ready to blow copper line when we did the bathroom. Seems like a pinhole because the well pump doesn't really come on too often , maybe once an hour.

[@Liam....]

The helium thing reminded me of a tip from Roger Bisby to tip a cheap bottle of aftershave or perfume into heating system then have a walk round and see if you can get a wiff of it anywhere, not sure how well it would have worked through a concrete floor though.

I was told a s a youngster doing this search and discover when it is large and hidden . If you can locate the center of the , be it system or dead wire , open access , now you have done 50 % of the search , it is either behind and further or ahead farther along . Now do the same on the effectided end ( divide at center from open section end or beginning ) depend witch way the pressure/signal is lacking . So basically divide 50 % is fore or aft , then divide that next 50 % and you only have a 1/3 left to investigate.

[@ipod1978]

First class video and quite surreal as I’m having somewhat of a similar type issue on my own system (again ffs). Old house, F&E system. Boiler is in good condition and has been/continues to be serviced every year, pump was replaced a year ago, both located outside in shed. Hot water cylinder on first floor with header and expansion tanks in the loft. Found a leak on both the flow and return literally 75mm apart from each other between two downstairs radiators right in the middle of a doorway when renovating the house. Both leaks had been "fixed" by a plumber during lockdown. Original pipe work to be fair was very poorly wrapped with no protection and then back filled with a very coarse concrete which caused the leak in my opinion. High traffic area too being in the centre of a bloody doorway so it was a no brainier and sheer luck that I even found it before the floors went down. Ok, now I’m hearing water coming in to the house via the mains even when no water is being run. Can’t tell if it’s on the heating side as the noise is evident even if the heating is switched on or off but only seems to happen really at night or at least I seem to notice it more at night. This has been going on for over a month now. Bathroom is downstairs with the pipe work running vertical. It’s boxed in and tiled. Toilet is mains fed so it’s not a leaky cistern. It’s definitely coming into the house because when I turn the stop cock off, the water noise ceases. I’m tempted to carefully drill into tiles at the bottom near the back of the toilet and use an inspection camera but then saw this and wondered if the thermal imaging or helium options would be viable on an oil boiler system? I both love and hate this fkg house all at the same time but this is my last hurdle but I’m at a loss. The first plumber I used who fitted the new circulation pump is to be honest a bellend, a guy from my previous town who I knew of but he left leaving a leak on the same "new" circulation pump he fitted right before trying to sell me a used oil tank. Second plumber who actually fixed my leaks even though he used plastic compression fittings, he did find and also resolved the leaking circulation pump issue ..during lockdown .. and did a fair job but while I genuinely rated the guys professionalism I was disappointed with the use of cheaper fittings however it got it fixed and my floors went down. Second time around when I called the second plumber out again i had to wait for just over 3 weeks to even get him here. When he did finally call out he only checked the ball valve in the loft and then as he was leaving informed I’d have to find any leaks myself but he recommended using leak sealer. I took the hit and spent £20 on MC4 at my local trade store and so far I’m still none the wiser but a little pissed off at having to bleed all of my radiators yet again caused by adding the leak sealer. Getting the hump to be fair even now. Sorry for gassing, feel like this turned into somewhat of a rant halfway through rather than simply asking if helium and thermal could/would work on an oil boiler F&E system. I have photos of all of my issues by the way that I took when renovating the house so I feel this customers pain having to hammer out concrete floors.

[@joshcowart2446]

Interesting I didn’t think you could use propress under a slab. I noticed the fittings look different over there as well. Ours have another bit of fitting past the o ring. We’re also not allowed to solder under a slab. We’d run 4 separate lines and tee it in the wall. If we absolutely had to have that tee or we’re doing a repair under a slab we have to braze it.

[@BTW...]

Use of soft solder is simply asking for trouble. Silver solder (brazed) results in a joint stronger than the copper pipe. Press fittings have a cost and strength disadvantage... only good for saving time and perhaps risk of using flame.

[@joshcowart2446]

@@BTW... couldn’t agree more. I always silver solder under a slab. I don’t know where your at but I’m pretty sure both codes in the US require it. Though not going to lie, I’ve soldered under a slab before. It was because I didn’t have any silver solder or only had a portable torch, I can’t remember. It was couplings so I figured it wouldn’t be under a lot of stress compared to other fittings

[@BTW...]

@@joshcowart2446 Here in Australia.

[@joshcowart2446]

@@BTW... seems like y’all’s code or at least what y’all consider best practice is sake as us. I didn’t mention pro press in my reply. I use it in repair situations when I can’t get the water drained out. I’ve also used them in situation where I’ve had to shut down a building and tee in to a main. It’s much easier to put a press tee and valve and then turn the water back on than it is to blow all the water out and solder. My company uses it on all commercial new construction. That’s for two reasons. One it probably saves them money on time and two they have a lot of young people who can’t solder. A couple of them can do it in a bind but they wouldn’t know what to do at a job where every single fitting is solder. However in the back of my mind I worry about those jobs. A repair is one thing but a whole job is another. I’m hesitant to install an o ring or any washer that I can’t change. I worry how those o rings hold up long term. I’ve seen solder joints that are 70 plus years old and fine. What happens to pro press in 20 yrs. I worry that’s it’s like a lot of things with building these days. They’re built to last 20 yrs but not longer. Another factor I just recently learned about was how they deal with freeze. I’m in Texas and we had the unprecedented 4 day snowstorm without power last year. One of our jobs had a 1” (28 mm) line running 50’ (about 15 m) under the floor on a balcony of a high rise. It feeds some planters up there. Contrary to popular belief when a line burst from freezing it isn’t directly from the expansion. Copper can take that and will even stretch. What it does though is create an ice block and then as it freezes more and more it create thousands of pounds of pressure down stream. This is what causes the pipe to burst. This pro press fitted line just pulled every single fitting apart. I think it was 3 couplings. The amount of damage is more severe because you have a wide open pipe now as opposed to a gash. Though once a pipe hurts it may put out so much that it doesn’t matter. Also they had to pull up the floor in 3 separate spots to repair it. Whereas solder it would have burst in one spot. Basically the cost to repair will be higher and possibly the damage will be more if it freezes.

[@BTW...]

@@joshcowart2446 Happy to say pipe freeze is very unlikely here, except in alpine zones. Bit of a worry that 'youngers' in the trade don't have solder skills, or don't seek to learn. Bit of a worry.. and how low can it go? I hazard a guess they don't know how to measure, bend and fabricate pipework too, without the need to add unnecessary couplings, Yeah, there is that 'instant gratification' of just grabbing a bucket of press fittings and wacking stuff together on the fly, with little need for accuracy, yet pretty certain no leakin' first time. And there is that factor of horror job sites where you can't get out of the place quick enough... the kinda places you remember years later. Man, basic soldering - I learned how to soft solder at 8 years old in the electrical/electronic field... and in my early teens plumbing fittings, a few years later in the sheetmetal fabrication field... some roof plumbing too (where now it's pop rivets and silicone bog to do the job... nasty. That was prior to any trade training. Late teens brazing copper, brass and steel. Done a fair bit of instrument plumbing during my apprenticeship (electrical fitting/mechanic). I had used swagelok fittings prior to that anyway. Early 20's it was a mix of electrical and refrigeration fitting... in-field fault diagnosis repair. Interesting trade the HVAC.. gotta know electrical plumbing, gas systems, mechanical, sheetmetal and air handling. Freezing... uhghhh. Seems a pressure relief 'fuse' would be a fair idea in the 1" branch you described. Press fit has it's normal design pressure with safety margin, sure. But to deal with freezing down a closed line.. a copper end cap and lower gauge annealed tube over a tundish drain located at every level... in an easily opened service stack... when extensive use of press fittings are used.. perhaps? I sure have my doubts about press fittings, but they are regarded as acceptable for hot/cold mains water and Nat gas supply here... so it follows that failure in service due to freeze is covered by building Insurance, I guess. I've actually seen press fittings in service, that have been accidental not crimped by original installers sitting there not leaking! Doesn't stop me having thoughts before sleep though, sometimes. But back to the heating line repair in floor... I see 4x 45 degree press fittings where a saddle set bend could have been used for clearance... OK, perhaps 1x 45 close to the main line tee. Then again... braze fabricate the repair piece including the Tee and use 3x straight slip couplings to patch it in.

Good job Pete repairing pipe under floor is sometimes hard but you did it so easily 🙂👍🏼💐

[@nickgiles1991]

Enjoyed the video, i have been doing leak detection for over ten years and there are very few vids out there... It is hydrogen we use not helium... actually it is 95pc nitrogen mixed with 5pc hydrogen and it is a really effective process although as you can imagine every job is different and poses new challenges... Although the gas is a smaller particle and should leak more easily.. it is cold which straight away is a change from the normal leak condition of heat up or cool down as the system is being used... push fit plastic system leaks can be very fiddly to recreate the leak. The infra red survey is best done from cold... leave off over night, that way you get sharp outlines and hopefully can pick up the bloom you are looking for before the heat spreads too much - in this case it would have been hard because the leak was at a nexus point of pipes in a tight area.

You're ALWAYS better off soldering those connections because the slip/crimp fittings rely on an O-ring to seal and they ALWAYS LEAK over time, while leaks in soldered joints are rare.

They surely leak when the tube isn't free of defects like dents or score marks, as seen in this case.

May be a silly question/point, but you re connected the pipes a different way to what they were originally, will that not affect it in any way?

You should always flush out any cleaners unless they are specifically designed to be able to be left in and you have a suitable filtration system, which is unlikely on a domestic installation. Typically these products contain chelating agents which remove deposits and films from surfaces, so if left in the system will continue to slowly strip material from the internal surfaces, particularly metallic surfaces. Remember also that you need to purge the deposits that the cleaner has removed, and they're not all magnetic!

Some plumbers are funny about leak sealer. I'm not. I think most of the "scare stories" are old wives’ tales. However, leak sealer should only be used in specific circumstances and caution should be paid to the viscosity of the leak seal. Heating pumps are designed to pump water, not maple syrup 😉 I usually add it to a large radiator. This means the leak sealer will be diluted before it flows into the boiler/pump. If the leak sealer is added to a magnaclean (on the return), then undiluted leak sealer will flow straight into the boiler/pump. I also run the heating for as long as possible before a hot tap is opened (for a combi). This means the leak seal will be diluted throughout the entire heating system before it is sent through the plate heat exchanger.

Hey how do those tap on fittings seal onto the tubes?? I used to work with my Dad many years ago back in the days when lead pips were still being used in some places and am just interested in how far technology has come in the meantime. Nice job by the way.

I think those fittings crimp on to the pipe. They look a bit like Yorkshire fittings, but they are solder free.

[@johngoard8272]

@@rubberneck2 Yes mate like In said technology has come a long way since I last did any plumbing I was used to cast iron baths and downpipes gutters etc etc

A pin hole in the heat exchanger going into a condense pipe ?

[@PBPlumber]

yeah the heat exchanger is connected to the condense pipe via the sump and trap so if your heat exchanger pin holes the water goes into the sump, thru the trap and out the condense pipe to a drain and you’d never know
