I've been haunted by an intermittent sewage smell in the kitchen ever since I moved in.
My first suspect was the waste pipe that goes from the kitchen sink into the outside drain. The drain was blocked so I thought it was the smell from the drain that was coming up the drain pipe and into the kitchen. I had the drain unblocked and it didn't quite solve the problem. The drain, even though unblocked, still smells bad at times.
I put on a cap on the washing machine waste outlet pipe, which was 'open' (no washing machine there yet); not really a proper cap, just a plastic yogurt cup upside down. That didn't help either.
I noticed the smell wasn't coming from any specific place (such as the sink or washing machine waste pipe) but concentrated in different parts of the kitchen. One time it would stay near the back door, another time it would hover above the worktop, etc.
Another suspect was the air brick, which is located next to the drain. I thought maybe the smell goes under the kitchen floor via the air brick when the wind direction is right, and enters the kitchen through the gaps in the concrete floor. So I put up a makeshift barrier made of a brick and old clothes to stop the air from the drain getting into the air brick. For a while I thought it had helped, but the smell is back again.
Any ideas of what it might be, please?
