Hi Fabi, Do you know where the water stockcock is to the whole property? (rather than just focusing on the bath tap) Camden would be responsible for locating the former (because that’s where their responsibilities end), not the latter.

I know there was talk of setting up a TRA in your neighbourhood, but don’t know what happened; it may be that other neighbours may also have some experience if you send them a comment via this (admittedly old) website to “connect” with them: https://stsilasnorth.wordpress.com/2014/11/30/first-agm-of-st-silas-north-tra/

Other people may have more useful suggestions!

p.s. I know my stop cock for the property is underneath the kitchen sink, but I somehow suspect that every block may have their stop cocks in different places.

In some blocks, there are stacks of bathrooms and kitchens one above the other and each stack has its own vertical supply. So, there may not be a single stopcock for the flat, and Camden’s repairs service will have either to turn the water off for you, or let yur plumber know how to do it. You say you have had no help from Camden, but not from which bit of the Council. You need repairs to sort out how to help you after two plumbers.

Totally agree with you, Camden should have some plans in place, especially if you have a shared water supply. some properties have more then one supply so it’s not easy. The repairs team should be able to contact the contractors who carry out the water testing to the tank rooms. If they can turn your supply off (you will be charged) a good plumber can freeze your pipe and put in your own stop cock.
