Hi all,just thought id mention this because i had a heated debate with 2 other gas engineers about the drop allowance when doing a tightness test.Last week 1 of the engineers left a 2 millibar drop at a property and said it was fine to do so as it was a g4 meter..i said ok but could you isolate all the appliances,he said yes...then i said well if you isolate all of them and then do another tightness test and it still drops 2 millbar then your not allowed to leave it because your not allowed ANY drop on pipework OLD or NEW,he said your allowed up to 4 millibar on a g4 meter in all cases...so to back my point up i got him to ring gas safe and they told him he was wrong...just thought id mention it incase any other engineers have been doing the same thing...let me know your views and what you think....
