Thanks Derek, I had a go at the questionnaire as I am looking to go for the gas training. First time with out the use of a book or classroom, I got 6/10 and would have got more but I changed my mind at the last minute, very enjoyable keep it up thanks. 👍👍
I swear question 4 is A? For a digital/electronic manometer I was told in my text books and exams it’s 0.20? However for a water gauge it’s 0.25? In regards to rise? Please can someone confirm/advise?
Got number 3 and 5 wrong. Should have got 3 but I over thought about the radiator blocking the vent. I remember doing ventilation and i do remember now about them having a notice on them.
The last question is pretty misleading. The maximum pressure loss allowed on an existing installation with an E6 meter with pipe nominal bore of less than or equal to 28mm is 8 mbar and it's 4 mbar on a U6/G4 meter. Yes, it's 1 mbar on a U16/G10 meter but that wasn't specified. Also, on existing with no appliances and new installations you cannot have any perceptible movement.
@@tomkatgastraining the question literally says pressure loss and not pressure drop. Pressure loss _is_ allowed on a system as long as its not too high a rate and there is no smell of gas. Also, the 'pressure drop' you're reffering to is technically referred to as the stabilisation phase of a pressure measurement.
@@L.C.Sweeney it is not about loosing gas from a leak it’s about how much you can loose between the meter and appliance when the appliance is running. You can tell that because no pipe size or meter is mentioned in the question.
I think question no 4 is wrong as permissible perceptible movement on u gauge is 0.25 but on digital manometer where it can register movement of less then 0.25 as most of digital manometer do then permissible movement is 0.20. For question no 10 i think there is no permissible pressure loss on pipe work at all. On the gas Instalation if there is a pressure loss under the limits that is permissible only subject to these conditions, as far as no smell of gas and no leaks on pipe work.
I thought this exactly. Found it in logic book ‘Basically Tools and Equipment’ - “No perceptible movement on U-gauge is taken as 0.25mbar” “No perceptible movement on an electronic gauge is taken as 0.2mbar”
The question was somewhat incomplete, you are right, if there is pipework only then 0mbar, but with appliances connected the pipework pressure loss is 1mbar.
Sorry i put it wrong way around. I meant to say perceptible movement on water gauge 0.25mb and digital 0.20 in the video at 2:25 the answer for digital is B:) 0.25 which is wrong.. should be A:) 0.20 Also 0.025 is 3 decimal place not 2 0.25 is 2 decimal

I reckon the wording on Q10 is wrong because no loss is allowed on pipework whereas a DROP in pressure of up to 1mb is allowed for on pipework installation because of resistance factors. eg LOST pressure as in an escape but DROP as in not as much force due to resistance.
You miss understanding the question it’s not tightness testing pressure drop it’s working pressure loss between the meter and the appliances so it’s not worded wrong but thanks for your comment and watching cheers
How do you expect a gas engineer who repairs and services gas appliances in domestic properties would know off the top of their heads British standards for that particular question 5
If you don’t know that standard you shouldn’t be doing the job because you should know what standards you have to work to otherwise how do you know what to do
@@tomkatgastraining That's a bit harsh mate, there is a ton of things i can't remember, but if i need to know i look it up. Never used 35mm pipework in 44+ years.
I got 9 out of 10 and have not done my test for nearly 10years(retired). I must say though that number 10 was worded a little misleading. If you had said working pressure drop between meter and appliance. Because otherwise it could have been taken for tightness testing. Perhaps it's my dyslexia? And I am being serious.
I don’t think so it asked what is the maximum pressure drop allowed across a system which is one MBar if it was to do with drop as a leak it would have had the meter and pipe work size
Love your programmes, helped me a lot . thank you
Thanks Derek Benny
As a trainee gas engineer wanted to thank you for your helpfull videos, I've learnt lots of great tips will keep watching every day! Appreciate it 🙏
Thanks for watching cheers 👍🏻
@@tomkatgastraining you da man!
THANKS DEREK GREAT QUESTIONS, KEEP THEM COMING PLEASE AS THEY KEEP THE MIND TICKING OVER
As ever always.....a great set of informative Q andAs
You are doing a good job. By teaching and passing on your great knowledge.

Well done Derek, keeps the mind working even if the body is not, especially at my age!! 😂
Thank you Derek, fantastic way to do revision! Please keep doing more Q&A

Go by the books always brother
question 4 is 100% A.
Well sometimes experts like Derek can make mistakes, we are all humans
The question is to 2 decimal places not 1 so the answer is b not a if the question was to 1 decimal place the answer would be a then
I said 0.2
Excellent, great questions. 😁👍
Thank Derek for your great videos
Great video again Derek 👍
Excellent.
Cheers Derek, great videos 👍
Great stuff, bit gutted I got 9 tbh. Keep your vids coming Derek, probably some of the best on youtube 👍
9/10 for me ...Got me good on number 10 fella ,thanks Derek.
I got 9 out 10, got the pipe clip distance wrong, i said 1.5 but its better to be less because its more clips and stronger. Good quiz.
Thanks Derek, I answered 9 questions keep going.
Thx good information
Thanks, keep them coming 👍👍👍
I like your quizzes
Please keep them coming only got questions 5 wrong.
Amazing ...
6/10 1st try. Great vid!
Got number 3 and 5 wrong. Should have got 3 but I over thought about the radiator blocking the vent. I remember doing ventilation and i do remember now about them having a notice on them.
Damn! Got me with the trick question, didn't pay attention to the decimals 😂
Davison here (trainee) got 9/10..thanks again for the video
I dont know how anyone could even dislike this, I had you use the books for a questions! Always learning, thankyou!

But that’s not what the question is asking read the question again because it’s asking for pressure drop not pressure loss 😜
@@tomkatgastraining exactly it’s misleading. And people who ask shit question like that are what’s wrong with the gas industry.
@@S29ORY just because you don’t understand or read the question correctly doesn’t make it misleading.

its 0.2mbar movement allowed on digital manometer, 0.25 on water gauge
It’s about the decimal point how can it be 0.2 when you have 2 decimal points?
I think question no 4 is wrong as permissible perceptible movement on u gauge is 0.25 but on digital manometer where it can register movement of less then 0.25 as most of digital manometer do then permissible movement is 0.20.

moon480 sorry question 4 is correct and you are allowed 0.25 Mbr movement but thanks for your comment and watching cheers 👍🏻
I think moon is correct
@@rusmatkhan6456am really sure it's 0.20 on digital and 0.25 on a water ugauge
According to the Logic book i'm learing from it's 0.25 on a water guage and 0.20 on a digital guage.
I thought this exactly. Found it in logic book
‘Basically Tools and Equipment’ -
“No perceptible movement on U-gauge is taken as 0.25mbar”
“No perceptible movement on an electronic gauge is taken as 0.2mbar”
Cheers Big D 10 out of 10
bugger! got last one wrong.. thought pressure drop on pipe work was 0...must do some revision!! thanks Derek.
Is the pressure drop from the meter to the appliance and not a leak?
The question was somewhat incomplete, you are right, if there is pipework only then 0mbar, but with appliances connected the pipework pressure loss is 1mbar.
@@406xud I agree a trainee wouldn't pick that up.
What does it mean the plume management kit must terminate in the same pressure zone?
ruclips.net/video/uSqvu3L8YvA/видео.html
Watch this video it will explain all
Question 10? Isn't that dependant on meter size, installation volume and smallest occupied space?
Nope
Do you have any commercial gas questions as well
Sorry no not at the moment
Digital doesn't mean electronic with a screen such as an analyser? Should be 0.25 mbar for a water gauge and 0.2 mbar for electronic ones.
Can we have more of these questions be brilliant
I did not get 10/10 but I did do better on this one than the previous ones. Thanks Derek 👍🏻
Asian Jon. Training.
Thought it was .2 for digital and .25 for u gauge
pete lovett it’s all about the decimal point if it says 1 decimal point it’s 0.2 but 2 decimal points it’s 0.25
Very helpfull
Safe
Just don't get why it is 0. 25 pressure drop at digital manometer?
Because it’s to 2 decimal places not 1 like you are told in training. To one decimal place it’s 0.2 but to 2 it’s 0.25
@@tomkatgastraining Thanks
Can i just ask the question about permissible rise on a digital gauge i thought it was 0.2 and water 0.25 can you clarify thanks .
It’s 0.2 to 1 decimal place and 0.25 to 2 decimal places it’s all about the decimal place
Wet helpful video
Only got 4 right and 1 don't know.
But I do drive a cab.
Perceptible movement on water gauge is 0.20mb. On DIGITAL,is 0.25mb
No mate on a water gauge it’s o.25 mbrs on a digital manometer to one decimal point it’s 0.2 and to 2 decimal points it’s 0.025 mbrs
Sorry i put it wrong way around. I meant to say perceptible movement on water gauge 0.25mb and digital 0.20
in the video at 2:25 the answer for digital is B:) 0.25 which is wrong.. should be A:) 0.20
Also 0.025 is 3 decimal place not 2
0.25 is 2 decimal

I'm starting my gas training on the 2 Jan
I only got 3 right 😔
Thanks for all the videos
question number 4 ?? shouldn't be 0.2 ?? is a digitl no manual ---
got 9 out of 10
Great effort 👍🏻
I guess Q 4 answer is 0.2 mbar?
No
questions are to easy
3/10 I’m ducked for my acs next month
You had better watch my ACS revision videos then 😜
Wow hard you think now things and you don’t haha 5 need more revision and read more books
