sorry to post in aibu, but i'm really desperate. looks like our neighbours' drains have blocked and their grey water (definitely) and toilet discharge (possibly - BOAK) is running into our property and down our drain. we've only just realised as the problem was pretty well hidden, but we can now see the (papery) residue and we're really upset.
the neighbours are lovely tenants, and are desperate to get it sorted. They tell me their landlord was supposed to come round this week to sort it out, but "failed to show". does anyone have any expertise in this area? i'm minded to go utterly fucking nuclear on the landlord who has apparently been ignoring drains problems for months according to the tenants. I have toddlers running round my garden, it's a health hazard!
to make it more complicated, next door is divided into 2 flats and there are two owners, both of whom rent out the property. we're definitely getting BOTH of their bathroom discharge... we spoke to the ground floor tenants only.
