Gas Leak - 2 plumbers haven't resolved

[Bkmstr]

We have been in our house (2 story) for 2 months. Smelled gas when we moved in around gas fireplace and room.

Gas company detected gas and shut off gas. Plumber came out and couldn't find a leak after conducting pressure test. Gas company came back out turned gas back on. Started to smell gas again after they left.

Company that did original install for fireplace came out. Found small leak between fireplace gas on/off valve (the key that you turn) and fireplace unit and resolved it. Within hours of them leaving smelled strong gas again.

Called second plumber who had trouble finding any leak. He replaced fireplace gas on/off valve (the key that you turn). Within hours of him leaving smelled strong gas again.

I have had the gas main turned off now for a few days, but still smell and detect gas strongly on 1st floor and get stronger the closer you get to the key shutoff. I also use handheld detector for readings. Gas furnace utility closet on second floor, does not seem to be issues there.

I'm concerned,we have been breathing this in off and on for two months, also been getting headaches.

Any thoughts/help on this issue would be greatly appreciated.

It sounds like it could be coming from elsewhere, known as migration, especially if you have had it turned off, or it’s upstream of the shut off. Can you get the gas company out again?

Yes, I think I should get them out here again. My concern was they would lock the main and make it more difficult for the plumber to rest. Not sure waht migration is, but googling it sounds like it may be a build up of gas if the pipe is run underground, which it might be since we are on a slab. Interestingly, even with the gas main off, seems to come and go. Evenings and mornings worse for smell and readings. Strong reading/smell 7:30 this morning for example. But by 10 no reading although I had windows open.

Ventilation will dilute or get rid of the smell.

Thank you for the information.

Get them to do a gas test from the meter on your pipework including the fire valve which is left open shouldn’t drop

Have you got suspended floors downstairs and is your house detached or semi?

I dont believe we have suspended floors, just slab underneath. Yes, detached single family home.

This need finding as a matter of urgency the emergency service will switch you off and disc the meter and place a warning notice on your meter was this done? Did said engineers carry out repairs and reconnect the supply ? , are you saying you can still smell gas when the gas supply is switched off ? If this is the case then it's a Cadent problem and could be a external leak? the emergency services will need to address that type of fault , a smell of gas is not acceptable and needs finding . Kop
