MEDIUM PRESSURE TIGHTNESS TEST. gas tutorial for trainee gas engineers on how to carry out the test.

[@marciajones8751]

wow that was by far the best tutorial I have watched on youtube. I have an exam tomorrow and was starting to panic but after watching this I completely get it! thank you so much. Absolute lifesaver!

[@tomkatgastraining]

Good luck with your exam

[@joeblogs1236]

Thank you Derek, as always Spot on. Please keep it coming. 👍

[@nw4021]

Thanks Derek, currently watching this video as I have my ACS initial coming up. I appreciate your own method making life easier as some of the methods proposed by the BS just seem to overcomplicate things... as usual, let's get on with it!

[@jpfrench1496]

Fantastic tutor! I love how thorough your tutorials are. And how you explain in detail. Brilliant vids. Love to have a watch and refresh the the mind it’s surprising how much you forget and need a little reminder now and then

[@garlic1558]

Best explanation I've seen about the working of this animal 😅 And certainly the easiest way to test it Keep on Derek 👍

[@mohammednazir8307]

Excellent video derek

[@mj0n4id36]

Interesting. A few different tests carried out. Will be watching this one a few times to get my head around it. One thing for sure, if I was to ever do this I will be doing it your way! Good video Derek. Thanks 👍🏻 Asian Jon. Training.

[@tonyleo7529]

I always strap a valve handle (with tape) to the MIV. So that next engineer has a handle to attach. This way the customer will use ECV in emergency.

Richard Hodgson lots of my videos have tightness testing in them 👍🏻

[@richardhodgson7443]

Tomkat Gas Training okie dokie, thanks

[@motabirdi4208]

Really needed to add some equipment/ unit as the pressure valve will show more fluctuation and the regulator has to differentiate the mean value, are used to test the unit until they were fazed out- as new stands party written as they have not understood or asked older gas engineers 🙏

[@hdhanji8006]

Top vid Derek, you should offer to re-write some of the gas regs and make it as clear as your demo :)

I'm not a gas engineer but I'll have a stab at why the let-by test is done at 7 to 10 mBar rather than checking against zero. Testing at 7 to 10 mBar is to check the manometer and it's piping are in working order. If the device stays at zero it could be that the manometer is broken or there may be a split in the rubber tube so no pressure reaches the test equipment, where as getting the pressure at the manometer up to 7 to 10 mBar proves it's functioning and a drop would suggest the test equipment is not properly connected or has a fault that means it cannot be relied upon.

[@tomkatgastraining]

Good try mate but the let by test is to see if the ECV is passing not a gas leak so if it was passing it would rise the tightness test is for a leak and if you found it’s dropping then you have a leak. Gas engineers are trained to inspect their test equipment before. Also if you put the pressure to 20mbr and it rises more than 0.25mbr on a u gauge then you would still see let by.

[@aghasahib4703]

[@AnEyeScream]

Thank you, Nikola Ditsov

[@pshemax]

I do agree with you Derek, it is so much easier to leave is at 0 during let-by. Question is: Will my assessor allow this during the ACS? If no, I could state that BS6400 does allow other ways, but there is a good chance he will try to fail me for being a smart ass :D anyway. Thank you for a great video. Those videos are a real help with preparation for ACS.

[@tomkatgastraining]

Peppe_UK as an assessor when a candidate can give a reason for carrying something out different from the assessment but still achieved the same results I would say well done you are correct but there are a lot of assessors out there who will follow the assessment to the letter and want to find anything to fail candidates. But if you achieve the correct results there should be no problem. Hope that helps 😜

[@pshemax]

@@tomkatgastraining Thanks Derek :) I will hopefully be able to test that in 5 years time at your training center :D If I have passed my initial ACS in 2 weeks. Take care

Hi derek Grey area , can you briefly explain correct procedure and purpose of the additional m.i.v ? Have never truly had anyone talk about or explain it’s exact purpose Cheers again dan

[@tomkatgastraining]

It’s the same process as a normal tightness test when using the miv

[@suewarrington8155]

👍Thank you..

[@gjmheating8857]

There so much confusion over the methods of medium pressure but I've always carried it out from the MIV that way it's always under pressure upstream they say you can just bubble test ecv and regulator

[@craigmaiden9353]

Hi Derek, I'm training currently, your videos are excellent, question for you, will you do a video on standing pressure, operating pressure, inlet pressure, burner pressures please and explain what they all are, what is it that is being checked and why, and what actions can/should we take if we encounter for example if standing pressure was under 21 or over 30, i know if over 30 then call the supplier but if under could there be other reasons why the pressure is low or is it just a problem with the ECV and you have to call the supplier?

[@tomkatgastraining]

Coming soon 👍🏻

[@craigmaiden9353]

@@tomkatgastraining brilliant, quick reply, look forward to it cause i've heard a few conflicting explanation hence why I'm asking a basic question just to get some clarification.

@@tomkatgastraining Hi Derek, I watched a few more videos excellent explanations really understanding makes much more sense thanks so much - ref the comment i put on a few weeks ago, you said coming soon in your feedback, I have been looking out for a video but unless ive missed it i cant see one covering the topic I suggested to cover, have you done one or is it still in progress? Or could you give me an idea when you will get time to go through it please. Thanks in advance, Craig

Roughly how much does it cost & how long is the course to add Medium Pressure to your gas qualification

[@tomkatgastraining]

It’s not a stand alone qualification it’s in with ccn1

[@chazzlebazzle69]

@@tomkatgastraining Though smart meter installers need ccn1 and that doesn't cover medium pressure gas

[@tomkatgastraining]

[@gjmheating8857]

The bottom line is there needs to be more training it's very common where I am, also when you call sgn to look at an installation that requires attention they dont actually do anything to resolve it, I've complained about lots of things like stickers etc but the gas industry just seems to have forgotten medium pressure and left it behind in my opinion
