0.5mb drop on tightness test - Should I be worried?

[EastMidsTiler]

Hi everyone,

Just looking for some advice/reassurance. My boiler had its second annual service today and the (gas safe) engineer recorded a 0.5mb drop on the tightness test. He assured my partner that this was nothing to worry about but as I wasn't home at the time I just wanted reassurance that this is okay? British Gas did the first service and it was nowhere near as comprehensive as carried out today. I suspect this result would have appeared first time around but either the test wasn't carried out or it wasn't recoreded.

As we only have the boiler and hob running on gas is there anyway this "leak" can be located? Isolate the applicances indivually? Sniffer test? Or is this harder to find than a needle in a haystack?

And lastly, is this likely to be increasing our gas bill?

I should say the engineer was in no way worried and has signed off job sheet as safe so I'm probably worrying about nothing.

Thanks,

Yes, if you want to work for yourself. It is not as simple like calling a company and getting self employed. You will need to hold a degree and that cost 12-15k

Ouch!

Seriously? I was surprised at your assertion, so did a bit if Googling. I can find no reference to support your statement. Even this does nit mention it:

So if in that situation, you had a 3mbar drop on a g4 metre, your conscience gets the better of you and you decide to investigate. You isolate the appliances and prove the pipework is sound. You then test each appliance individually and find the gas valve on the fire is passing. What then? Do you leave it or have to condem it?

Once you have gone down that route thats it. I had a gas sqfe routine inspection not long ago and I had a 0.5 drop on the job he came out to. The gas safe guy confirmed no smell of gas on existing install its a pass. If I had decided to isolate appliances I would be obliged to find it.

It depends on the job doesn’t it. In regards to a plumber you cannot run a company without having the degree.

Is it a degree in plumbing or any degree?

Strictly plumbing, gas,oil, solar, heat pumps, literally everything about plumbing and heating

Ah. So now it is a Degree, not a Masters. And only certain business'?
TBH, I am still not convinced.. This mentions what is required, and mentions plumbing. Nowhere does it mention degrees:
