I moved in to a private property last year and have had problems with the outside drain for as long as I can remember it is connected to the gutter and my kitchen and always seems to be blocked I know its nothing from my kitchen blocking the drain so am wondering if it may be the guttering or a third party the drain has a grate that seems to be cermented into place so it is hard to see where it is blocked it is in a communal alley so it tends to flood it out on a daily basis so I really need to sort the problem out soon so I was wondering as I am on a low income if anyone knew of any way of unblocking the drain at minimal expense
