Fluorescin Dye

[jaydebruyne]

Has anyone ever used fluorescent dye and UV torch to trace leaks in heating systems?

Any good?

Any reviews...?

What do you guys do if leak sealer doesn't work and there are no visible leaks from boiler of rads/valves..?

pipes in floor?

and thermal would be the best have a look at the flir one

Any recommendations on one? They range from £150 to £1500.
I was looking at this: https://www.pass-thermal.co.uk/flir-mr160-imaging-moisture-meter

This is mine, FLIR one I think, attaches to iPhone.
Pictures are leak from pipes in concrete floor.


Hot pipework is clearly defined where leakage occupies a larger area,
The copper was bleeding through, no hole just like a sponge.

Looks great.
However, I'm a little confused by the thermal image.
So I can see the pipe, clearly, which then disappears under the mass of heat which I would have thought was just heat from the pipe.
How did you know it was leaking there? (I know I'm being thick, sorry!)

That's the misses Xmas present sorted. Go nice with the ring spanners she got last year.

There is somewhere a picture just outside the room, which shows the pipe again,from then on it was educated guesswork, luckily it was right.

So basically if that pipe wasn't leaking, there wouldn't have been that heat mass around the pipe like that?

there would have as not insulated and dont think it was leaking the way he said it also you will see the ground around a leak heating up i think

I think this is it

Follow pipe clearly defined then just heat

ahh ok.. might have a look at the iPhone flir then.. I had a guy on the kamco course say it was good too

You would clearly see the pipe with hot water, the FLIR one has a temperature point as well, bright yellow is the pipe, then a random mass of cooler hot water, which has bled from the copper shows where the leakage was. If you look at the last picture you can see the pipes separated by a large area, that's where the leak was

Just ordered the Flir One - how exciting

I've got the CAT S60 phone with a built in Flir camera and its awsome! Best phone i've ever had. So many uses for thermal imaging.
