    Anyone know the precise leak testing methods and limits for LPG in a motorhome/caravan?

    The British Standard seems to be unavailable to normal punters (BS EN 1949:2011) without parting with lots of money.

    Before anyone says "You can do that!", I'll just say, yes I can. Indeed, I'll sleep a lot better knowing it's been done "properly" by someone who's own life is at stake rather than by some "professional" who takes yer money and gives you a certificate that's probably valid for as long as it took him to write it.

    I've personal experience of professional gas men cocking things up so please, don't lecture me. If you don't know the answer please move onto another thread.

    Thank you.

    if you are so intent on doing the job properly yourself then part with your money and buy the necessary documents.

    the only people likely to know on the forum are those who do it for a living and arent going to part with the info freely.

    Anyone contemplating undertaking any gas work on their motorhome would be best advised to check their insurance cover first. Our insurance requires that heating and cooking equipment be serviced by a properly registered engineer.

    I would but £160 for them seems a bit steep! I see where you're coming from so I won't hold my breath.

    Cheers.

    Good point. I'll check but there was certainly no question along the lines of "Has your gas system been properly maintained/serviced/certified when I took out the policy.

    Doesn't mean it isn't in the small print of course.

    It's one of the endorsements on our policy (Highway LV through Frank Pickles).

    Think it's a little more than that

    The exam every 5 years is greater than that

    Plus gas safe registration

    Then your indidual specialty

    Then the learning offsite whith someone educating you

    Learning the the various informations

    That may or may not be required for each exam

    Give the wrong answer and watch your livelihood walk out the door

    As you can't work on gas pipe work or appliances till

    Reacreditid

    one other thing get it wrong and you may face a criminal prosecution

    And go to prison

    I was a emergency gas engineer

    glad I am no longer at the sharp end

    Trying to keep people safe

    Sorry for the rant no wish to upset anyone

    It's just a reason not many professional persons are willing to give
    Information as freely as people require

    It looks easy when you watch someone test a gas installation
    But it's the results and how they are interpreted that makes you safe !:thumb:

    Sure I'll tell you, first you need to volumise the system to a minimum of 600Ml then pressurise it to 5 times normal working pressure. Leave it for five minutes for the temperature to stabilise and then if necessary adjust the pressure back to 5 times normal working pressure. After a further five minutes the pressure must not have dropped by more than 5 mbar. This test should be done with all stopcocks open and all appliances off. You will need the apropriate equipment to connect to your gas system and volumise it plus pressurise it and it obviously needs to have an accurate pressure gauge.

    Yes BUT, I'm not doing it for profit so virtually none of what you've quoted above applies.

    I have an even greater vested interest in doing it safely than a "professional" as I'll be sleeping in the van. I've also seen botched "professional" gas work so I don't buy into the argument that professional is always best.

    We both want the same thing, a safe gas system. I just don't happen to think that that *has* to be a done by a professional.

    Regards

    Tim

    Cheers Dave, that more or less concurs with figures I've come across elsewhere since I posted (although I was quoted 150mbar rather than 5 x working pressure. Not hugely different though). Reassuring to get the same info (and more detail on the testing procedure). Much appreciated!

    out of interest dave when you say volumise do you mean you have to add capacity if the pipework volume is less than 600ml also does the 5mb drop apply to that volume only

    How's this? I can maintain the massive gas fired heat treatment furnace we have in work, which is big enough to fit any motorhome inside, but I'm not allowed to touch the gas system in my motorhome!
    But hey the rules are the rules, there are some pretty inept people out there who need protecting from themselves, just watch You've Been Framed, unfortunately the rules effect us all, and it can be very frustrating, especially for me!

    I had assumed it might be an acronym, but if so I cannot find a meaning (plenty for TOFU though).

    Not many possibilities if it's an anagram, only four letters and two the same. I can only think of FOOT or possibly FOTO, neither of which seems to fit the bill, so tell us all.

    I found a meaning in urbandictionary, too rude for here though.
    Not sure it's actually an acronym though.

    No the "rules" allow you to do almost anything to your own motorhome as they are exempt from gas regs unless hired out in course of a business. You do need to be able to "prove your competence" though.
