Derek in part one of ACS revision takes us through tightness testing for revision for the ACS gas assessment. In these videos he aims to teach us the process by just getting on with it.
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.
Well done, please don't worry much about the people complaining, this is about Gas and its a dangerous thing. Please take your time and explain properly for our safety 🙏
Thanks Derek I am currently training to be a Gas engineer through Access Training and this is so helpful and actually better than the webinars I attend. feels easier to follow because its such a short period of time.
Nice video Derek. Well explained 👍🏻. The timing on which I watched this video was pretty good. ACS revision! By the way, I don’t think you waffle at all mate. Keep up the good work. Loving it. Asian Jon. Training.
thanks again legend. you're really helping out the new engineers do things the right way. we need more people like you who are genuinely helpful and not just talking nonsense just to sell products! Many thanks!
Nice one Derick seems strange you not waffling. Like the new 10 min format and glad you got rid of the background music, much clearer without it. Thanks Rick Kirk
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
Great video. Short and to the point. The nightmare question..... what classifies as an existing installation, not new. Always a question I get asked. Honestly, I don’t know the definitive answer. 🤷🏻
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 ?
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
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 RU-vidrs house you will see how important it is if you find the drop on the carcass.
@@philipcooper4136 connected is it was gas going to it isolated means you have turned the gas supply off at the service valve and of course disconnected means removed from the gas supply
So are you saying if there is appliances connected , we are allowed drop , then what about if there is appliances connected but I turn off the appliances gas valve and there is drop on the pipe work but no smell but still same old installation?
Hi , doing my Acs atm But I don’t understand clear what happened if a let by test fail . What you need to do if you can’t fix it !!!?? Need to cap the ECV valve off and contact the gas emergency number ? Thanks
Let by fail is classed as AR. It’s only dangerous if you are working on the gas pipe is new boiler install. It’s our ESP problem so inform them of the problem.
