| Comment | That's a bit of a bodge. Probably need something like [this drain connector](https://www.screwfix.com/p/mcalpine-drain-connector-black-32-40mm/3502v) instead of that bodge. And they shouldn't really be using the 90 bend directly like that.
This probably leaks if you use your sink too, so it's probably your responsibility. You could try to interest the factor, but the general rule is that if a pipe only serves one property it's their responsibility
Not hard to fix (assuming there's not a head of dirty water in the pipe - unlikely or it would come up out of your sink).
But you've got neighbours downstairs and you don't want to rain on them, so better to get someone in rather than DIY if you're not sure of your skills. |
