Great wee tip, in a past life I was a heating engineer ( a good one even if I say it myself lol ) and crawled about under floors looking for leaks. I will most certainly use this tip
Now that's brilliant. Uv dye works if you can see the pipework. The problem with finding tiny weeps is the hot pipes evaporate the weep before you can see it, UV dye and smelly vision combined. You can't go wrong.
Thank you so much for this great tip.we had to keep topping up our boiler almost every day..a plumber came and checked the boiler and said there must be a leak under the floor somewhere...but he couldn't offer any further advice..so another plumber came with a thermal imaging camera...her couldn't pinpoint the leak but said it was possibly in a certain area of the kitchen.. I was extremely loathe to start ripping up our laminate flooring as I had only laid it four years ago...so I saw your video and gave it a try..I put some very strong patchouli oil into the bathroom towel rail and waited... one morning a couple of weeks later came downstairs and the hallway smelled strongly of patchouli oil..I got on my knees and had a good sniff and pinpointed an area by the living room door...so I took up a small area of flooring and bingo..a leaky pipe...a pipe that had been badly fitted to cross over another pipe and had been touching the chipboard subfloor so everytime the pressure of people walking on it it rubbed a pinhole in the pipe. All fixed now and with minimal damage and upheaval ...thank you again Roger for this great tip.
Brilliant timing. Our CH pressure dropped just a few hours before seeing this. Hadn't happened in a couple of years. Topped up the water as usual and ready to call plumber. Now off to nearest source of junk perfume
Thank you SO much for this very clever idea - pure plumbing wisdom - so grateful to you for posting this as I have to detect a hidden leak and was wondering how to do this without destroying the whole house!
Great video. Thanks for the tip. I’ve tried this and can smell the perfume now in the garage around the boiler. Can’t smell anything outside near the flue. The pipes around the boiler feel dry and no sign of water. Could it be leaking into the condensate drain?
Thanks for this tip. Combined with using a thermal imaging camera to trace the pipes this tip narrowed our leak down to the hallway under the concrete. (Which didn't show leakage on thermal image) Leak now isolated and heating back on. Took about 4 days for the smell to show up and I just noticed it one day walking through from room to room. This saved us £900 on trace and access bills and your other video ('6 plumbers couldn't solve this' video) showed that the hydrogen sniffer test is not necessarily any better!
I guess about 0.5-1.0ml - a lot of drops. I didn't measure it. Really I think any amount of really smelly perfume would do. Afterwards we just had work done on the pipes to divert around it and added some anti corrosion. There was no need to drain as it was high up in the pipework so no flooding.
great tip I run a student residence in paris 2 houses one heating system very big over 50 rads cast iron pipes etc and leaks have been a problem also heating engineers just dont want to know I bought thermal camera to find pipes under the floor I will try this next leak thanks
An absolutely brilliant tip, thanks. You’re probably not looking for suggestions for video topics, but, if you are, one on wet / dry testing of new pipe work would be interesting. (Especially as I have some to do 😀) All the best and I hope you cope OK with the new restrictions down South, as well as keeping the mutated virus at bay...
Great tip Rodger, I've had a slow leak for a year, I've cut walnut floor boards with my oscillating tool. Bought a bendy camera we've now got lots of 8mm holes I've got plug up at some point. I'll be giving this a go. Merry Christmas.
I feel your pain, I’ve had every part that can leak on the boiler changed. Finally I added 2 bottles of Fernox leak sealer, 3 months still holding pressure. When it fails I’ll be trying Rogers technique and start crawling under the floorboards. Hope you find your leak.
How does the perfume react with the rust inhibitor or the boiler? Are there any bad chemical reactions? Will it eat through the pressure vessel membrane?
ex htg engineer (now air con) 18 years experience i never even thought of that. or heard of any one using it. lost count times ive done a combi upgrade and the heating keeps loosing pressure boards up checking rads etc HEADACHE re piping rad circuits etc aparently put bread in the pipe so can solder pipes put milk in to trace drsins but never heard of this one thank you
Does it require a full bottle for a house with 7 radiators? Do I need to bleed the whole system after fixing a leak? I wonder if the perfume can affect the inhibitor.
Great idea Rodger, thanks. One question though, would it be safe to add a perfume that has say alcohol or any other flammable ingredient in it? Thanks.
I got a new combi, pressute keeps dropping can't find the leak anywhere! About to give this a go and see what happens. But im concerned, is perfune safe to add to CH? Don't want to ruin the boiler. Thanks
Nice one Roger. I've got a TRV which hisses when on. I notice when I turn it in a direction it goes away. I can't see any water but does concern me. About 5yrs old now. Any thoughts? Love your tips thanks.
TRVs do that. I have one Ecocal that does the same thing. They just have that point where they are about to close and the water rushes through a tiny gap. You might solve it by turning the lockshield valve to slow the water through the radiator.
Great thank you… does this work if there’s a leak in the indirect coil in the cylinder and the domestic hot water is filling up from the heating side… I’ve just recently added a new radiator and only notice an air build up in a top floor rad now the heatings back on… great tip again!
I've got a open vented log fire boiler setup with underfloor and radiators that drinks about 1lts of water every 7 days and for 4 years I've been stumped, having tried everything to find it......I shall do a sniff test....thanks for the brilliant idea.
We had a similar problem recently and it turned out to be a pipe under the floor. The smell tracing is well worth trying. If you have a dog put some aniseed in the heating system and the dog will find the leak.
Hi. Quick question. As I am just about at my wits end trying to find a leak, and like another guy on here said, I also have 8mm drill holes in floorboards all over my house where I’m peeking under floor with my snake cam. But Is there any danger that the high alcohol content of perfume may have an explosive effect if exposed to a naked flame within the boiler e.g if the boiler or heat exchanger is faulty?
@@SkillBuilder We have a leak in the downstairs heating loop. The leak is under the concrete floor somewhere. Tried the thermal image camera but the boiler won't stay running long enough to heat the water. Will try your tip next, thanks.
Hi mate,,I’ve got a draft somewhere in the main bedroom but I can’t find where it’s coming from,,when it’s cold outside is when I can really feel the draft,, have you got any ideas what I can use to find it 👍👍
Hi Ant If it isn't from the windows then it is probably coming up from the floor. Often it is a tiny gaps around the joist ends and the wind blows in from the cavity wall. How old is the house?
Other than an elusive leak, active system corrosion generates gas which accumulates, is compressible (unlike water) and shows apparent loss of pressure.
So the water is reacting inside the system and being converted to gas . But won't the overall volume and pressure remain the same? Won't it still reach the pressure saturation point of the sealed system? I suspect if the water as turned to gas, it would be easier to escape via the connection joints or via other valves in the system. That might lower the pressure.
Great idea. But what about 'Internal Leak Sealant' - what's your opinion of this? Screwfix sell it, but I don't want to push the issue further down the road and make it more difficult to fix later, if that's what it's going to do.
If you add something smelly, eg like the perfume you mentioned, then when you turn on the hot tap in eg the utility room then you will smell the perfume. We know we have a leak in the utility room as a couple of tiles get a little wet/damp when the heating is on but these tiles are not near the radiator and we believe that the heating pipes underneath the floor are not under those tiles. Obviously we need to source the leak which could be anywhere really. It's likely the water is coming to the surface at a weak point in the tiled floor? Is there any device that can detect our leak?
Hi, did you find your leak? I think I have one and wondered if you could hear yours? I can still hear a running water sound when I turn off the mains water valve so I know it's on the central heating running from loft tank. Did you hear your leak?
I have spent months (since may) calling out 4 different plumbers... Had the heat exchange changed and I'm still losing pressure!... can you send a link on how best way to open a radiator to get perfume in!... ?
Add it to the magnetic filter? Close the valves, release pressure on the top nut,drain a bit of water out the bottom nut, and undo the lid. I hope they left you the proper tool with the filter. Add your perfume. Lid back on. tighten nuts, undo valves and re pressurize system, remove any air pressure in filter with the top nut air valve.
Top tip, many thanks Roger and Merry Christmas. More reasons then to stick with an old fashioned vented system, where of course I don't know it's got a slow leak, but a bottle of F1 in the header every year keeps it happy? Persuade me either way with another video on that, "Vented Vs Unvented" unless you already have one. Thanks again.
I think we have a leak. Our boiler pressure is constantly zero (although all the heating is still working fine.) and we have a patch of laminate flooring in a bedroom that is clearly becoming uneven (it feels like its soggy underneath). What do we do?
I love the idea but have yet to see anyone in the comments section that says this actually works. I wonder if the dilution of the tiny amount of perfume in such a large amount of water will be enough to create a smell, smelly enough to track?
Peter The boiler is on the ground floor. There is a full height towel rail on the top floor, I’d estimate the top of that is about 7m above the boiler..
Excellent Roger you are clever, I have another idea how about Adding lavender oil and sending the dog 🐕 round they have much better smell sense then humans??
I read somewhere recently that the thing about dogs having a better sense of smell is a myth. I am not sure how or why the know that and I suspect it is fake news put out by cat lovers.
