Leak detection fluid

[Basildog]

For those that say washing up liquid is fine , don’t waste your money on proper LDF they say

 

[Cush]

i would have thought they would have rinsed it off afterwards.

Penny wise …. Pound foolish

 

[St3v3]

I have LDF, but only for convenience. Is what you see there actually a problem? Remind me what the test life of the bottles is?

The worst part IMO is the rust on the top surface of the bottle which shouldn't be susceptible to a bit of washing up liquid, no matter how bad for your sensitive pinky it is lol.

It's a bit like how we know WUL is now bad for rubber seals. That co-incided with the introduction of very expensive silicon spray....

Cynic? Moi?

It's a good heads up for the fairy liquid brigade. I think my leak detection spray was around £2 . I keep it at the side of a gas bottle in the locker and do periodic checks.

Good lord how often was it sprayed on! Every day? For a year?
That is corrosion from constantly being wet.

All my working life I've used a bit of washing up liquid and topped up with water in a trigger spray bottle as leak detection spray, never seen anything like the above, with the exception of compressor suction pipes which are constantly wet maybe refrigeration brass fittings are better quality

But you can't tell them that the salt in washing up liquid causes corrosion, they saw their dad use it in the 50s and it still works. It is fine in an absolute emergency, but wash the area well afterwards and dry thoroughly

I now have a sniffer but always used car shampoo before that.

that may tell you have a leak.. but won't pin point accurately ..

 

[scotjimland]

You can buy a bottle leak detector for about three quid, less than a pint of beer ..

In the washing up liquid the Ammonia they put in for example will lead to stress cracks appearing which will seep into all parts of the valve and lead to brass parts failing catastrophically and simply put valves will leak in some way or form. Chlorine in the washing up liquid will cause the same damage to stainless steel parts

also

Don't assume all leak detection fluids are the same as it is known in the industry that some leak fluids have significance ammonia and chlorine in them which has caused brass parts to completely crack and shatter even before LPG under pressure was put in the gas system.
If your unsure of the specification of the leak detection fluid on sale elsewhere then visit the GAS IT webshop to be assured it’s all safe and fit for purpose to BS EN 14291 requirements.

Checking for leaks, what do I use.

It will to the nearest 1-2 cm as it has adjustable sensitiviy, and that is close enough for me, but I also have a tin of none corrosive spray.

 

[MisterB]

Those that do use washing up liquid, should actually only use the bubbles from a water/washing up liquid after frothing it up. Then of course clean and wipe it off afterwards. The amount of actual 'soap' is minute OR at least should be.

 

[scotjimland]

On the oil and gas production platforms I worked on, if anyone used anything but an approved gas leak detector fluid, they would be on the next flight home..

but there will always be those who know better and to save a few quid will ignore good advice ..

Used both over the last 34 years needs to be wiped off after both types of liquids used , if u haven’t access to ldf washing up liquid is fine here and there

Makes me cringe when I hear of people washing their cars with fairy liquid.

Why? It's their car they can do as they please. Remember all the faded red ford's
