Gas cock instal regs

[Radioman]

Should there be a gas cock between a boiler and the Meter? If so then how near the boiler should it be?

 

[Ermintrude]

This is covered in your training. If your not trained or competent then you shouldn't be working on gas!

Why do you need to know.

 

[Dotty]

Giving the op the opportunity to reply to Ermi's question before I close the thread.

I have had a new boiler installed in the loft 8 weeks ago by local gas safe engineer. Last week I had the front yard dug out to provide off road parking. We discovered the gas supply pipe was only 40mm below surface. Called out national grid see if it was live or not. They have messed me about but that's another storyline. During safety check they ascertained that I have a gas leak in the house of 4mb in 30 secs. We turned off the hob cock but cannot find any cock on or near the new boiler. The gas safe eng that installed the boiler has not attended yet as "too busy". Nat grid have capped off the meter so I have no heat or cooking for 7 days. I am now building a case against the fitter who did the install of boiler and hob. New fitter will want to isolate the boiler so I am looking for the location of the boiler gas cock and cannot find it.
As I had no smell of gas in the house I suspect it's a faulty boiler and the gas is venting up the flue.

Edit

I am still waiting for ng to tell me why I should pay for the burying of the pipe that was too near surface in the first place.

You don't need an aecv before the boiler as there is one built into it.

Tell your gsr that if he doesn't attend within a reasonable timeframe you will be calling someone else out for which you'll be expecting him to pay AND will possibly incur the risk of his being reported to Gassafe.

Do this verbally and send him a recorded delivery letter saying the same thing. Inform him of this.

If you don't give him a reasonable chance (note the word reasonable is subjective) then you'll find it difficult for any recompense.

at least give the fitter a chance, you dont know its his faulty work, dont jump to conclusions

What boiler is it?

 

[Scott_D]

The digging/vibrations may have disturbed a joint
Someone may have stepped on the gas pipe in the loft

Look in your users manual for the new boiler and it will tell you where the gas valve is.

 

[stevetheplumber]

8 weeks is a long time for a gas leak of that size not to smell if its internal if its a boiler gas valve passing its possible it wasnt when the boiler was installed as to the service pipe only being 40 mm deep how would the fitter know that?

 

[Aquazone]

4mb in 30 secs? That would just drop the gauge out between let by stabilise and TT. Surely no fitter would leave that? I would bet it's either a disturbed joint or passing gas valve. If the latter then it would still be under manufacturers warranty.

mainly due to the fact that you want to put in parking and it needs to be a certain depth, the fact it wasnt deeper before is of no consequence now.

 

[AWheating]

as other have said the boiler will have its own gas isolation valve built into it. This is normally situated under the appliance at the connection of the gas pipework. As for the leak, its highly unlikely a competent person will miss a full drop on a tightness test.

Give the engineer the chance to attend in a resonable time.

You are changing the use of the ground outside, this means the pipe needs to be at a deeper depth for car traffic over foot traffic. Your change not the gas boards.

 

[plumben]

I found a 5mbr drop in one minute once and it turned out to be the gas valve in the boiler, only showed up sometimes as I only found it as it was my first drop test and my boss was showing me how to do it after he'd already tested

I am trying to as he is a friend of 15 years standing but he keeps putting us off. Suspect as he has been paid in full.

Worcester combi

Look in your users manual for the new boiler and it will tell you where the gas valve is.

Unlikely as the leak is house side of the meter and the meter is outside and been tested with a sniffer. I would look in the manual if I had been left it.

There was no smell of gas in the house at all. I'm prepared to pay for the new pipe but why should it take 12 weeks?!

 

[samwilko]

Worcester combi s have gas isolation on them. Anyone competent enough to tell you you have a 4mbar drop will know where to find it.

Surely he should have left you the manual and filled out the Benchmark!

 

[newcastle phill]

Boiler in loft...no smell of gas..
Any external gas pipework upto loft ???

 

[REDSAW]

if the board came out and found a drop in pressure then they would have isolated the boiler and any other appliance in turn to proove it was a faulty appliance or pipe work. a 10 min job!!
did they actually go to the boiler?
was the boiler turned off and not calling for heat/water when it was tested?

odd very odd..

The drop test was done by the National Grid engineer that capped off the meter.

 

[Radioman]

Yes I would have expected them to but National Grid do not enter the premises as it is not their remit. I isolated the hob but had no idea where the boiler cock was as no book and the installer would not pick up. As the house has had a major refurb it is just possible that a carpet fitter has nailed a pipe but I am surprised at the lack of smell.

 

[Radioman]

No all is internal and now boxed in and tiled. No smell of gas in the loft either.

 

[PhoenixServices]

Possible it could be in the boxings, especially if they are vented to outside.

 

[PhoenixServices]

And how come ng won't enter the house. Surely they should check the appliances are shut off or have to re-light them at times.

Don't know but all he said was its not his job to find a leak in the house just establish that if its not their service that's leaking or the meter then cap off the meter until a GS engineer can sort the house side out.

 

[Radioman]

BTW just been told that NG are to relocate the pipe this Thursday at no cost to me as it on the street plan as plastic but it is iron. Should have been replaced when the meter was relocated 20 years ago. Attached picture shows current situation

. Ground level dropped by 130mm
