We are having a problem with sewer smells coming into the house. It's particularly bad in the kitchen. We are on the end of a block of four houses with shared drains. There's a pathway at the side of our house where the drains run out into the street.
We've had Thames Water round twice and Dynorod round twice. Between them they have found the drain under the manhole cover in the path to be blocked on occasion. But clearing it there are still sewerage smells in the house later on.
They also CCTV'd from the stack on our property out to the shared drain and also down the shared drain. No problems were found out to the road.
But still the smell persists on an almost biweekly basis. Any ideas what this could be?
I'm on my next phone call to Thames Water today.
