so if you was to tightness test a job you haven’t worked on. During the let by test there is a drop. You then test for tightness on an e6 and it drops 1mbar over 2 minutes and pipework not all accessible and appliances not all with iso valves. Would you deem it unsafe

Appreciate the feedback. We used a full can of leak detector on all the new joints (probably about 15 in total) over and over again. And nothing. Not even a slight bubble. The engineer was happy that it was in the safe limit. But for some reason he was checking.
Would you guys walk away from that or not?
also is it possible rocol leak detector wouldn’t pick it up? is there a good gas sniffer on the market that’s reasonably priced and more reliable than ldf. Thanks
I wouldn't deem it unsafe going off that information.
I would find out how much is leaking and where from in this situation (you have made alterations).
Cutting the boiler off temporarily and testing pipework only would take less time than squirting LDF everywhere and once you have done that you will be a lot clearer on what is leaking. Then you can decide whether it is safe to leave it.
You have to put things in perspective. If this was an existing installation with appliances connected and no smell of gas on a domestic property with an E6, then I would be happy to forget it. I would still need to let by test the ECV.
If there is gas passing through that and leaking out elsewhere, you cannot carry out testing accurately.
ROCOL, is good LDF in my opinion. It will find most things where joints are concerned but it can depend on the position and size of the leak, whether you see it or not.
Sniffers are available from ten's of pounds to thousands of pounds depending on your needs.
They are well worth having.
The Engineer you are working with may well have made his/her mind up going off a vast amount of knowledge and experience for all we know. It may look like they had doubts but I wouldn't think they would leave it if there was any danger to be fair. Have you discussed this in detail with them? If you ask why they arrived at the decision they did, you may be surprised at their thought process. It might make perfect sense.
