Yesterday when I came home the downstairs of our property stank of petrol. I called the gas company and they came to check there was no gas leak which there wasn't. They said it's likely someone had flushed petrol down the drains, and as the pipes run under our house the smell/petrol would be under the house.
My partner spoke to our neighbour, we are semi detached and our driveways are attached, he said he had spilt a tiny bit of petrol when cleaning out his tools but the smell is still really strong a day later.
I feel uneasy that there is potentially a load of a petrol under the property.
My mum suggested calling the fire brigade to flush the pipes out?
No idea what I should do or how long it will last.
Any ideas?
