Hi, Great site, always managed to find the info I'm looking for without posting, until now! I live in a mid terrace and have a blockage in a downpipe which is situated between my house and my neighbours. It collects water from the main roof and from my bay window roof and my neighbours bay window roof. Its clearly a shared drain and, as the houses were built pre 1937, I was hoping it would be a section 24 drain and the responsibility of the local water company to come and unblock. However, I've been told that things have recently changed re section 24 drains but havent been able to find much online and am still waiting for the local water company to return my call, their website isn't much cop either! Does anyone have any up to date info? Thanks!
