If the ECV is letting by then you don't need to cap the ECV off as is not escaping it's just not able to be isolated and is letting by, you can leave it on and attach a warning label and contact the gas supplier and take your reference number. Then once it's fixed return to the job and continue with the tests..... Cheers for the video it is the best tightness test video on RU-vid
RU-vid Hero thank you, I totally agree with you and you do not have to cap it off. I have had it twice in the past and I have capped it off and waited for the supplier to attend site to repair, I personally wouldn't leave site (I'm over cautious) I believe you cant be to careful. 👌🏻
Interesting differences. In Chile we follow the Australian standard with the test at 180 mm H2O (18 mBar, natural gas) or 280 mm H2O (28 mBar - LPG) with a permissible drop of 7 mm H2O (0.7 mBar), and the test goes on for 5 min or more depending on the length of the pipework tested.
It's always great to see how different countries do different tests etc, in our country the tests for LPG and oil are very different. Thank you for the comments
Dude never on the pipework only on the appliances themselves. If the tightness test fails. Isolate all the appliances and retest. If it fails on the pipework. Then it's fail full stop. Then you inform the responsible person. If they agree for repair then repair it. If not cap it cutomer signed notice and onto cadent 😊
This is true, you shouldn't use pure washing up liquid it a very old timers trick however if it's all you have to hand them I would rather use it and make sure there isn't a leak than not use it if I'm honest😂. Make sure it's properly wiped afterwards and it won't be an issue. Thanks ray
@@rayc1503 that's not correct the permissible drop is due to the meter its nothing to do with the appliances. Hence different allowances for different meters.
@@liamc9425 I've been GSR for over 10 years now. You're allowed absolutley no drop on new pipework. If it's old or existing 4mb on the appliances not the pipework of U6 meter. 8mb on the appliances not the pipework of an E6 meter. If there's any drop at all your supposed to isolate all appliances and test the pipework. If that fails Sir then it's a fail. If in any case the customer reports to you he/she has smelt gas then it's also a fail, simple. Go back to your handbook and correct me if I'm wrong or look up BS 6891:2015: or IGEM/UP/1B TT & purging. Passed my GasSafe inspections and ACS no problems. It's more common sense then anything else.
No sir that meter is a u6, E6 is a small electronic gas meter with digital backlit display, internal shut off valve. A U6 and SC6 meters incorporate a measuring unit with a two litre cyclic volume designed to accurately meter volumes in all natural gas and LPG applications. 👌🏼💪🏻
There are only two real reasons this would occur, if there isn't a strainer placed into the regulator or that the distance between the regulator and the valve in insufficient (mainly new builds) If this is the case and it does lock out the solution is very simple really.
Thanks, I'm planning to cap off an old unused gas fire. I'm not a professional, but I do consider myself competent and want to do it safely and by the book. This clarified the test procedure for me.
John Warner yes really. In past times "washing up liquid' was the go to product for gas fitters, any 'bubble' solution is fine to use such as soapy water for instance. However I should have stated in the video that I wouldn't recommend using washing up liquid as it 'can' corrode the fittings if left! However IF it's all you have to use then it will do the job. It's always better to test than not to....... (Agreed as a gas fitter you should carry leak detector with u, like I do)
