Gas leak detector

swiftcamper said:
I agree with you some so called professionals are some what lacking.
I always use a paste or sealant on all my compression fittings it is a commonly discussed point among plumbers, for me it lubricates the joint and you tend not to get those little seeps you often see.
Most people actually over tighten compression fittings.

Use (or not) of sealing compound, from my experience, is the best way to start a fight on a plumbers forum ever. It's right up there with discussing ****** on a wild camping forum.:lol-053:
 
I can see where you are coming from and your reasoning. It's a real pain in the back to get an old olive off and many times the pipe is also distorted and won't seal with a new olive. But I would rather have a GAS joint sealing tight with no extra sealing. Even if I have to fit a new fitting an pipe.

As long as I don't see an instruction of the fitting manufacturer asking to use a sealing compound, I will not use anything.

Do you know for sure how long your anaerobic sealing compount is going to last? Has the manyfacturer declared it fit for the purpose you are using it?
I am not trying to pick on you (or anybody else), but personal preference is not what is important when it comes to safety. You obviously experienced enough to judge what is safe and what not but there are a lot of people who aren't and may just take everything they read as face value and feel they are doing a good job.
 
Precisely and what trade qualifications or trade experience do you have

I am not in the plumming trade but have worked around vehicles and engineering for all my life. (and a lot of other activities)

My "qualification" comes from experience and working alongside qualified tradesmen be it on my own projects or projects
I have been involved on a professional level which required me to get to know what's going on.

If I don't have the knowledge for a job, I either call a professional or talk to one to judge if I can tackle a job myself or stay clear or at least read the relevant
papers.
 
So just another expert DIY chappie putting lives at risk with knowledge they have picked up in the "Plumming " trade Gas fitting is a world away from Plumbing.

Hi all, this opened a can of worms. But if you had a gas tester to check your joints sealer or no sealer then you could tell me if they are any good
 
i missed most of this discussion. i learn everything from experience, and every caravan ,camper or mobile library etc that had gas fittings always used Calortite.
i use it for 2 other reasons- house kitchens don't corner at 60mph and bounce up dirt tracks
and i have come across joints on old vans that were only finger tight,and the joint turned on the pipe, but the sealant prevented it leaking
just an aside- years ago i worked making dangerous gaswork safe on holiday homes on the Algarve. an author called Len Deighton had a house overlooking the beach at Albufeira.his gas bottles were in a kitchen cupboard,and i had to vent them through the wall. unfortunately, the cobbled street outside was about 4'' higher than the kitchen floor. took me 2 days to lift hundreds of granite cobbles,dig down, and re-lay the buggers !

why I am not surprised about your reply....

well I will you experts alone with my unqualified blurp and will just stick to my teutonic engineering.

At what point have I given advise that would risk lifes? You just so high up your own arse that you don't even consider other peoples experience.
You need to move on with the times old man, stuff these days is designed so that it works and doesn't need fiddling. I have learned since I was an aprentice to do stuff right the first time. In the years I am living in England I have learned one thing, we british don't like to be told. We know better. Even for arguments sake.
 
Has someone poured a bucket of negative energy over this forum?

IF you feel that someones opinion is WRONG, then offer another opinion that you think is CORRECT.

NEVER ATTACK THE PERSON!

I wonder if people will understand this message?

Vehicle brake pipe connections utilise compression unions, just a nut over a pipe flaring, no sealant used. The pressures encountered in a brake line are countless times that found in a gas line - typically 32 mbar.And the conditions brake unions are subject to are usually much more severe than a gas union would experience.

Hi Was thinking on buying one of these hand held gas detectors to carry in the van they start from £20 upwards thought it would be quiet handy to have, I carry a aerosol spray leak detector but this would be a lot easier especially when you have to change the gas bottle in the dark.

The Question has of any members got one and if so witch one and how good is it.

I asked for feedback on GAS TESTERS

no never met him,though i had read all his books. but i did screw all his pictures to the wall to stop his tenants nicking them, he'd lost loads and it infuriated him!
as for the cupboards, they weren't against an outside wall, unfortunately, and because wood was rarely used in house construction, they were made of rendered brick uprights with marble worktop and shelves, and made to suit the average Portuguese, who at that time,not long after the revolution,was about 4'10'', so a gas bottle barely fitted !
 
But that's what I've written brakeline pressure is countless times more than the 32 mbar in a gas line.I know perfectly well the likely difference in pressure between the two I could have used bracketting to make my point clearer it would appear.

I am merely pointing out that brake pipe compression joints rely on their integrity using no sealant. Why should gas unions be any different. New connection or reconnection makes no difference same high standard should apply. Properly installed brake pipe unions don't normally shake loose.So why would gas unions.

i do like that word, 'blurp' ta !
 
In my experience of gas fittings, those wary of brazing tend to use compression fittings, I personally prefer to braze where possible, a soundness test afterwards soon tells if it is a sound joint. where a compression is used then sealant is a good idea precautionary perhaps but as Swiftcamper suggests stops any seeping.

On Air con that works at similar pressures to those suggested by byronic compression joints are illegal. so everything has to be brazed ,crimped joints when diferent pipe sizes are required , flared joints where two pipes of the same diameter are to be joined.

Swiftcamper intimated that some things can get you locked up and the above is one of them allowing refrigerant into the atmosphere is a criminal offence !! hence tested with nitrogen ...equally a ne pipe installation with LPG is tested with air to 50 mbar if I remember correctly for soundness.

What needs to be remembered is all this is part and parcel of thye exams one takes and ultimately for good reason

The method was the same, don't know what the times and pressures were
