Hi Derek, have my 1st re-assessment in October so am just using your videos to jog my memory, but have found them to be really straightforward, where things need to be explained it’s done simply - so as not to end up feeling blinded by science ( regs or bs….) - thank you. Also considering they are freely available to all and you ask for and respond to comments why individuals find the need to be critical or negative says more about them than you. Anyway thanks again.

Thank you So drop can not be on pipe work or meter Then if we have drop permissible System is pass but we need to actually isolate the appliances and make sure drop was on them not on pipe work or meter So In reality Tightness test does not really says if drop is on meter or appliances or pipe work Is for whole system So if meter is leaking or pipe work Then we only find out by isolating the appliances But again. Even when we do that Then we need to do tightness test stage by stage of installation by isolating the part of system and eventually use electronic gas leak detector. To really find out where the leak is Weather on pipe work or meter And that’s also proses of finding leak and if is meter then to report it and get it replaced or fix the section of pipe work which is leaking

Hi , if you are at an old installation let's say , you have a drop within tolerance , then you isolate all appliances , who's to say that an isolation valve could not be passing on one or all the appliances enough to make you think there is a drop in the installation pipework ? Some stuff I feel gets confusing ? Can you clarify how you would proceed , do we need to go that far ?

The problem with this table and the IGEM/UP/1B, there is not actually a requirement for us to prove the leak is on appliances or pipework, according to the IGEM and Gas Safe. We’ve been having this debate for years which has resulted in a meeting with IGEM a couple of months ago to clear it up. The answer is there simply is no logic behind the fact that you can have a leak on existing pipework with an appliance connected to it unfortunately. It all harks back to a time long ago when all this research on leak rates was undertaken. The new version of the UP/1B has quite rightly proposed to remove this table, but we are just waiting to see if this will stick after the ‘industry’ review?
@tomkatgastraining2 жыл бұрын
IGE/up/1b is up for revision this year if you look at the draft it says 1mbr drop for all meters. I think it’s to combat this problem
@julianhearn11292 жыл бұрын
@@tomkatgastraining yes indeed, they are proposing to go down the same route as the LPG criteria, whereby you can apply more than the 1mbar, if you are prepared to calculate the IV. Then you can apply leak rates based on IV, which makes a lot more sense to me.

Hi, great video. I just want to query the permissible drop process as this is different to what I was taught and what gas safe technical have told me. I was told it has passed a tightness test if it falls in the permissible drop criteria for that installation and further investigation is not required ie attempting to trace a leak. I was told that an isolated appliance is still a connected appliance so the permissible drop would still be allowed with appliances isolated and only if you disconnected all appliances and tested would you not be allowed a permissible drop. I'm not trying to be smart here, I'm genuinely trying to clarify in my own mind, the best way of doing it as I can see the point of both sides here. Especially if a landlord complains you have capped his tenant off and have quoted him for a very expensive repipe then another engineer says you're wrong and turns it back on. Any info appreciated
@tomkatgastraining2 жыл бұрын
The regs are quite clear it says permissible drop with appliances connected and zero drop on the carcass. If you watch my video on the gas leak we found at the KZfaqrs house you will see how important it is if you find the drop on the carcass.

If it’s dropping on the let-by you take it to 20mbrs and time for 2 minutes to see if you have a leak there is no permissible drop for let- by just permissible rise as the test is just proving it’s not passing
