Hi - I moved into a new house recently (quite old - built in 1915). There is one bathroom and the waste from the kitchen sink, bathroom basin and bath drain into a gully outside the kitchen. The toilet waste goes into a vented waste pipe which also has dishwasher waste attached.
The set up looks like this:
The central pipe takes both guttering and bathroom waste. The left pipe is kitchen sink waste (inc washing machine) and the bottom right pipe is another gutter. The vented pipe is behind it.
I noticed there was a bit of a smell outside when the toilet is flushed. When I removed the cap to the gully, I noticed that when the toilet is flushed, water flows into the gully from a small slit on the right:
Sorry the picture isn't great - I had to flush the toilet and then run downstairs before the water finished draining to get the picture. Hopefully you can see there is water seeping through this small slit - presumably from the waste stack. My first question is, should this be happening? The small slit where the water is coming through seems like it's part of the set up, i.e. not a crack that's appeared. I know very little about outside drains so I'm not entirely sure what's normal.
If this set up is correct, what might be causing an odour?
Many thanks for any advice / suggestions offered.
