Okay, so I have a really poor sense of smell.
We have recently moved house and there is a smell a bit like gas in the under the sink cupboard. I'm not 100% sure it is, though. It is noticeable but not super strong.
I have tried taking apart the plumbing under the sink to see if perhaps there was something trapped in the drain pipe from the last owners - but it's clear as far as I can see.
The smell is noticeable when you open the cupboard doors but dissipates after a bit if they're left open. The gas cooker is the other side of the kitchen.
Is there anything it could be besides a leak? Would it be wasting emergency services time to ring the gas emergency line?
