Smelly Smells

[Billy Bodger]

Hi there, I recently laid laminate floor in my downstairs toilet. To do this I had to remove the toilet and the wash basin. Since I completed, there is a distinct ‘sewerage’ smell coming from the room. I have checked the toilet and I am happy that this is sealed correctly, I am more concerned about the sink.

The house is only a few years old. The waste pipe from the basin just drops into the waste pipe through a small hole in the floor. Should there be some sort of seal around the pipe when it drops through the floor to stop the smell coming into the room?

Any advice/tips would be very much appreciated.

Is there a trap on the basin?

Yes, there is a trap on the basin.

How does the basin waste pipe connect to the drains. Follow it and see.

The waste pipe just drops through the floor, it doesnt fasten into the pipe (in the ground) at all, it just drops through a whole in the floor (which is like a plastic plate). There is no seal between the pipe and the plate so I assume unwanted odours are getting in from there.

Do you have a manhole in your house?
