GAS LEAK in existing 22mm copper pipe direct to boiler

[Mike Jackson]

There's no problem with running copper externally, the issue is protecting it from damage.

It's covered in B.S. 6891:2005+A2:2008 8.15.2 Above ground external pipework.

Above ground external pipework shall be protected against the risk of mechanical damage, e.g. in car ports

So any pipework run along a driveway should be protected from mechanical damage. This could be achieved using a mechanical means to protect copper but it's easier and cheaper to run low carbon steel which is inherently more resistant to damage.

And theft

If there has been a reported gas leak no drop can be left, smell or not.

thats not actually true ive been called to reported leaks where another gsr/ hob fitter had tested and found a 2 mb leak and have just confirmed its only 2 mb and the customer hasnt smelt anything so just confirmed with them its ok to leave generally you dont get called to a leak unless the owner has smelt it
but i do agree in this case it should have been capped and labeled
can the new run not be run high level to remove the mechanical/theft problem

DEALING WITH SUSPECTED GAS ESCAPES
When responding to the following situations, the gas installation shall be tightness
tested in accordance with clause 5.3.2 (existing installations). However, to
successfully pass the test, there shall be no perceptible movement of the gauge
reading and there shall be no smell of gas

yes but its excepted that within tolerance leaks are allowed on appliances with no smell or are you talking about pipework only tam?

 

[tamz]

Not after a reported leak mark including appliances

theres probably a assumption in that reg that a reported leaks come after a smell of gas,its been traced to a appliance within tolerance or not

 

[tamz]

It applys to all reported smells of gas whether reported to a private gsr guy or an esp.
Once it has been reported as an escape it is then down to you to find it or make safe.

so where does permited drop come in to the equation once ive found a drop its officially a reported leak as i would note it on paperwork therefore by your interpretation i cant then leave it

 

[kay-jay]

You can leave a permissible drop only if there is no smell of gas. If there us a smell then it becomes a reported leak.

If there is no smell only an engineer would discover it by testing...

If no smell you can leave it.
